Sap ABAP Faqs,Interview Questions
What is an ABAP data dictionary?-
ABAP 4 data dictionary describes the logical structures of the objects used in application development and shows how they are mapped to the underlying relational database in tables/views.
What are domains and data element?-
Domains:Domain is the central object for describing the technical characteristics of an attribute of an business objects. It describes the value range of the field. Data Element: It is used to describe the semantic definition of the table fields like description the field. Data element describes how a field can be displayed to end-user.
What is foreign key relationship?
- A relationship which can be defined between tables and must be explicitly defined at field level. Foreign keys are used to ensure the consistency of data. Data entered should be checked against existing data to ensure that there are now contradiction. While defining foreign key relationship cardinality has to be specified. Cardinality mentions how many dependent records or how referenced records are possible.
Describe data classes.- Master data: It is the data which is seldomly changed. Transaction data: It is the data which is often changed. Organization data: It is a customizing data which is entered in the system when the system is configured and is then rarely changed. System data:It is the data which R/3 system needs for itself.
What are indexes?-
Indexes are described as a copy of a database table reduced to specific fields. This data exists in sorted form. This sorting form ease fast access to the field of the tables. In order that other fields are also read, a pointer to the associated record of the actual table are included in the index. Yhe indexes are activated along with the table and are created automatically with it in the database.
Difference between transparent tables and pooled tables.- Transparent tables: Transparent tables in the dictionary has a one-to-one relation with the table in database. Its structure corresponds to single database field. Table in the database has the same name as in the dictionary. Transparent table holds application data. Pooled tables. Pooled tables in the dictionary has a many-to-one relation with the table in database. Table in the database has the different name as in the dictionary. Pooled table are stored in table pool at the database level.

ABAP/4 Query can generate the following 3 simple reports: Basic List: It is the simple reports. Statistics: Reports with statistical functions like Average, Percentages. Ranked Lists: For analytical reports. - For creating a ABAP/4 Query, programmer has to create user group and a functional group. Functional group can be created using with or without logical database table. Finally, assign user group to functional group. Finally, create a query on the functional group generated.
What is BDC programming?- Transferring of large/external/legacy data into SAP system using Batch Input programming. Batch input is a automatic procedure referred to as BDC(Batch Data Communications).The central component of the transfer is a queue file which receives the data vie a batch input programs and groups associated data into “sessions”.
What are the functional modules used in sequence in BDC?- These are the 3 functional modules which are used in a sequence to perform a data transfer successfully using BDC programming: BDC_OPEN_GROUP - Parameters like Name of the client, sessions and user name are specified in this functional modules. BDC_INSERT - It is used to insert the data for one transaction into a session. BDC_CLOSE_GROUP - This is used to close the batch input session.
What are internal tables?- Internal tables are a standard data type object which exists only during the runtime of the program. They are used to perform table calculations on subsets of database tables and for re-organising the contents of database tables according to users need.
What is ITS? What are the merits of ITS?- ITS is a Internet Transaction Server. ITS forms an interface between HTTP server and R/3 system, which converts screen provided data by the R/3 system into HTML documents and vice-versa. Merits of ITS: A complete web transaction can be developed and tested in R/3 system. All transaction components, including those used by the ITS outside the R/3 system at runtime, can be stored in the R/3 system. The advantage of automatic language processing in the R/3 system can be utilized to language-dependent HTML documents at runtime.
What is DynPro?- DynPro is a Dynamic Programming which is a combination of screen and the associated flow logic Screen is also called as DynPro.
What are screen painter and menu painter?- Screen painter: Screen painter is a tool to design and maintain screen and its elements. It allows user to create GUI screens for the transactions. Attributes, layout, filed attributes and flow logic are the elements of Screen painter. Menu painter: Menu painter is a tool to design the interface components. Status, menu bars, menu lists, F-key settings, functions and titles are the components of Menu painters. Screen painter and menu painter both are the graphical interface of an ABAP/4 applications.

Layout sets. - Layout set consists of the following components: Windows and pages, Paragraph formats, Character formats. Creating forms in the R/3 system. Every layout set consists of Header, paragraph, and character string. ABAP/4 program.
What is ALV programming in ABAP? When is this grid used in ABAP?- ALV is Application List viewer. Sap provides a set of ALV (ABAP LIST VIEWER) function modules which can be put into use to embellish the output of a report. This set of ALV functions is used to enhance the readability and functionality of any report output. Cases arise in sap when the output of a report contains columns extending more than 255 characters in length. In such cases, this set of ALV functions can help choose selected columns and arrange the different columns from a report output and also save different variants for report display. This is a very efficient tool for dynamically sorting and arranging the columns from a report output. The report output can contain up to 90 columns in the display with the wide array of display options.
What are the events in ABAP/4 language?- Initialization, At selection-screen, Start-of-selection, end-of-selection, top-of-page, end-of-page, At line-selection, At user-command, At PF, Get, At New, At LAST, AT END, AT FIRST.
What is CTS and what do you know about it?- The Change and Transport System (CTS) is a tool that helps you to organize development projects in the ABAP Workbench and in Customizing, and then transport the changes between the SAP Systems and clients in your system landscape. This documentation provides you with an overview of how to manage changes with the CTS and essential information on setting up your system and client landscape and deciding on a transport strategy. Read and follow this documentation when planning your development project.
What are logical databases? What are the advantages/ dis-advantages of logical databases?- To read data from a database tables we use logical database. A logical database provides read-only access to a group of related tables to an ABAP/4 program. Advantages: i)check functions which check that user input is complete, correct,and plausible. ii)Meaningful data selection. iii)central authorization checks for database accesses. iv)good read access performance while retaining the hierarchical data view determined by the application logic. dis advantages: i)If you donot specify a logical database in the program attributes,the GET events never occur. ii)There is no ENDGET command,so the code block associated with an event ends with the next event statement (such as another GET or an END-OF-SELECTION).
What is a batch input session?- BATCH INPUT SESSION is an intermediate step between internal table and database table. Data along with the action is stored in session ie data for screen fields, to which screen it is passed, program name behind it, and how next screen is processed.
How to upload data using CATT ?- These are the steps to be followed to Upload data through CATT: Creation of the CATT test case & recording the sample data input. Download of the source file template. Modification of the source file. Upload of the data from the source file.
What is Smart Forms?- Smart Forms allows you to create forms using a graphical design tool with robust functionality, color, and more. Additionally, all new forms developed at SAP will be created with the new Smart Form solution.
How can I make a differentiation between dependent and independent data?- Client dependent or independent transfer requirements include client specific or cross client objects in the change requests. Workbench objects like SAPscripts are client specific, some entries in customizing are client independent. If you display the object list for one change request, and then for each object the object attributes, you will find the flag client specific. If one object in the task list has this flag on, then that transport will be client dependent.
What is the difference between macro and subroutine?- Macros can only be used in the program the are defined in and only after the definition are expanded at compilation / generation. Subroutines (FORM) can be called from both the program the are defined in and other programs . A MACRO is more or less an abbreviation for some lines of code that are used more than once or twice. A FORM is a local subroutine (which can be called external). A FUNCTION is (more or less) a subroutine that is called external. Since debugging a MACRO is not really possible, prevent the use of them (I’ve never used them, but seen them in action). If the subroutine is used only local (called internal) use a FORM. If the subroutine is called external (used by more than one program) use a FUNCTION.
What is an ABAP data dictionary?-
ABAP 4 data dictionary describes the logical structures of the objects used in application development and shows how they are mapped to the underlying relational database in tables/views.
What are domains and data element?-
Domains:Domain is the central object for describing the technical characteristics of an attribute of an business objects. It describes the value range of the field.

SAP ABAP Tutorials :Architecture and Design
We have discussed regarding SAP Navigation in the first lesson.Here we are going to discuss regarding system architecture an design.
SAP SYSTEM KERNAL :
In SAP terminology, a service means a service provided by a software component and this component can consist of a process or a group of processes and is then called a server for that service.
Software components that use this service are called clients. At the same time, clients can also be servers for specific services.
A server often also means a computer (host) on which software components that provide specific software.
The fundamental services in a business application system are presentation services, application services, and database services.
In a one-tier R/3 System configuration, all processing tasks are performed on one server, as in classic mainframe processing.
Two-tier R/3 System configurations are usually implemented using special presentation servers that are responsible solely for formatting the graphical user interface. Many R/3 System users use Windows PCs for example as presentation servers. An alternative two-tier configuration (not shown) is to install powerful desktop systems and to use these for presentation and applications also (two-tier client/server).
This type of configuration is particularly useful for processing-intensive applications (such as simulations) or for software developers, but due to the additional administration requirements is usually used for test purposes only.
In a three-tier configuration, separate servers are used for each tier. Using data from the database server, several different application servers can operate at the same time. To ensure that the load on individual servers is as even as possible and to achieve optimal performance, you can use special application servers for individual application areas such as distribution or financial accounting (logon and load balancing).
User screen input is received by the SAP presentation program SAP GUI, converted into its own format, and then sent to the dispatcher. The processing requests are then saved by the dispatcher in request queues and processed according to “first in / first out”.
The dispatcher distributes (dispatches) the requests one after the other to the available work processes. Data is actually processed in the work process. The user that sent the request through the SAP GUI is usually not assigned the same work process, because there is no fixed assignment of work processes to users.
Once the data has been processed, the processing result from the work process is sent through the dispatcher back to the SAP GUI. The SAP GUI interprets this data and generates the output screen for the user with the help of the operating system on the frontend computer.
During initialization of the R/3 System, the dispatcher executes the following actions, among others:
it reads the system profile parameters, starts work processes, and logs onto the message server (this service will be explained later).
Within ABAP, SAP OPEN SQL is used to access application data in the database, independent of the corresponding RDBMS. The R/3 database interface converts the open SQL statements from the ABAP statements into the corresponding database statements. This means that application programs written in ABAP are database-independent. Native SQL commands can be used in ABAP.
When interpreting open SQL statements, the R/3 database interface checks the syntax of these statements and automatically ensures the local SAP buffers in the shared memory of the application server are utilized optimally. Data frequently required by the applications is stored in these buffers so that the system does not have to access the database server to read this data.
The operating system views the R/3 runtime system as a group of parallel, cooperating processes. On each application server these processes include the dispatcher as well as work processes; the number of work processes depends on the available resources. Work processes may be installed for dialog processing, update, dialog free background processing and spooling.
The lock mechanisms in today’s relational database systems are usually not able to handle business data objects (such as customer orders) that affect several database tables. To coordinate several applications simultaneously accessing the same business object, the SAP System provides its own lock management, controlled by the enqueue work process.
In order for the system to execute lock requests, you must first define a lock object in the ABAP Dictionary. The lock object contains tables whose entries are to be locked. A lock object consists of a primary table. You can also define additional secondary tables using foreign key relationships (the name of a user-defined lock object must begin with "EY" or "EZ").
You can specify the lock mode ("S”: shared lock or "E”: exclusive lock) for a lock object. An exclusive lock (mode "E") can only be set if no other user has set a lock (“E” or “S”) on the data record. The same user can request additional "E" or "S" locks within a program call sequence (call chain).
If a lock object is activated, the system generates an ENQUEUE and a DEQUEUE function module.These function modules are called ENQUEUE_ and DEQUEUE_ and are used in ABAP code to lock and unlock data.
The asynchronous updating usually used in an SAP - LUW allows the system to temporarily collect changes made by users and then, at the end of the dialog phase (in the second part of the SAP - LUW), make the necessary changes to the database in a separate update work process. To ensure data consistency, the resulting database change (which includes every “dialog step change”) is executed in only one final DB - LUW.
Background work processes are designed for periodic tasks such as reorganization or the automatic transfer of data from an external system to the R/3 System.
Background processing is scheduled in the form of jobs. Each job consists of one or more steps (ABAP reports, external programs, or other operating system calls), that are processed sequentially.
You can also set priorities (from "C" to "A") so that certain jobs are prioritized.
Job processing is not generally triggered immediately (immediate start). Instead you specify a start date and time when you schedule the job. It may also be necessary to start jobs periodically, for example, system control jobs repeated on a fixed cycle. Using the program SAPEVT, you can trigger a job start at the operating system level.
The background scheduler is responsible for automatically triggering the job at the specified time.
The background scheduler is an ABAP program that regularly looks in the scheduling table for jobs to be executed and then ensures that they are executed (RDISP/BTCTIME, default 60 s).
Spooling refers to the buffered transfer of data to output devices such as printers, fax devices, and so on. In distributed systems, networked administration is necessary for this output.
The R/3 System spool mechanism can supply print requests to printers and external spoolers both within a local network as well as across wide-area networks (WANs). The spool mechanism works with the local spool system on each server.
Spool requests are generated in dialog mode or during background processing and are then set in the spool database with details about the printer and the print format. The data itself is stored in the TemSe (TEMporary SEquential object) database.
When data is to be printed, a print request is generated for a spool request. This print request is processed by a spool work process.
The operating system spool takes over queue management and ensures that the required data is passed to the output device.
An instance is an administrative unit that combines R/3 System components providing one or more services. The services provided by an instance are started or stopped together. You use a common instance profile to set parameters for all the components of an instance.
A central R/3 System consists of a single instance providing all the necessary R/3 System services.
Each instance has its own SAP buffer areas.
The message server provides the application servers with a central message service for internal communication (for example, trigger update, request and remove locks, trigger background requests).
The dispatchers for the individual application servers communicate through the message server, which is installed once in each R/3 System (it is configured in the R/3 System profile files).
Presentation servers can also log on to an application server through the message server. This means that you can use the message server performance database for automatic load distribution (logon load balancing).
SAP SYSTEM KERNAL :
In SAP terminology, a service means a service provided by a software component and this component can consist of a process or a group of processes and is then called a server for that service.
Software components that use this service are called clients. At the same time, clients can also be servers for specific services.

To ensure that the load on individual servers is as even as possible and to achieve optimal performance, you can use special application servers for individual application areas such as distribution or financial accounting (logon and load balancing).
The central process in the R/3 application layer is the dispatcher. Together with the operating system, the dispatcher controls the resources for the R/3 applications. The main tasks of the dispatcher include distributing transaction load to the work processes, connecting to the presentation layer, and organizing communication.
User screen input is received by the SAP presentation program SAP GUI, converted into its own format, and then sent to the dispatcher. The processing requests are then saved by the dispatcher in request queues and processed according to “first in / first out”.
The dispatcher distributes (dispatches) the requests one after the other to the available work processes. Data is actually processed in the work process.

Data frequently required by the applications is stored in these buffers so that the system does not have to access the database server to read this data.
In particular, all technical data such as ABAP programs, screens, and ABAP Dictionary information, as well as some business process parameters usually remain unchanged in a running system, making them ideal buffering candidates. The same applies to certain business application data, which is accessed as read-only.
The operating system views the R/3 runtime system as a group of parallel, cooperating processes. On each application server these processes include the dispatcher as well as work processes; the number of work processes depends on the available resources. Work processes may be installed for dialog processing, update, dialog free background processing and spooling.

If a lock object is activated, the system generates an ENQUEUE and a DEQUEUE function module.These function modules are called ENQUEUE_ and DEQUEUE_ and are used in ABAP code to lock and unlock data.
The start of an SAP transaction is also the start of an SAP - LUW. SAP - LUWs are completed either by a "COMMIT WORK" in the ABAP code, or by the completion of the corresponding asynchronous update (second part of the SAP - LUW). As explained previously, each dialog step in an SAP - LUW is processed by one work process, as is the case for the DB - LUW. Each database change is executed in its own DB-LUW.
The asynchronous updating usually used in an SAP - LUW allows the system to temporarily collect changes made by users and then, at the end of the dialog phase (in the second part of the SAP - LUW), make the necessary changes to the database in a separate update work process. To ensure data consistency, the resulting database change (which includes every “dialog step change”) is executed in only one final DB - LUW.
Background work processes are designed for periodic tasks such as reorganization or the automatic transfer of data from an external system to the R/3 System.
Background processing is scheduled in the form of jobs. Each job consists of one or more steps (ABAP reports, external programs, or other operating system calls), that are processed sequentially.
You can also set priorities (from "C" to "A") so that certain jobs are prioritized.
Job processing is not generally triggered immediately (immediate start). Instead you specify a start date and time when you schedule the job. It may also be necessary to start jobs periodically, for example, system control jobs repeated on a fixed cycle. Using the program SAPEVT, you can trigger a job start at the operating system level.
The background scheduler is responsible for automatically triggering the job at the specified time.
The background scheduler is an ABAP program that regularly looks in the scheduling table for jobs to be executed and then ensures that they are executed (RDISP/BTCTIME, default 60 s).
Spooling refers to the buffered transfer of data to output devices such as printers, fax devices, and so on. In distributed systems, networked administration is necessary for this output.
The R/3 System spool mechanism can supply print requests to printers and external spoolers both within a local network as well as across wide-area networks (WANs). The spool mechanism works with the local spool system on each server.
Spool requests are generated in dialog mode or during background processing and are then set in the spool database with details about the printer and the print format. The data itself is stored in the TemSe (TEMporary SEquential object) database.
When data is to be printed, a print request is generated for a spool request. This print request is processed by a spool work process.
Once the spool work process has formatted the data for output, it returns the print request to the operating system spool system.
The operating system spool takes over queue management and ensures that the required data is passed to the output device.
An instance is an administrative unit that combines R/3 System components providing one or more services. The services provided by an instance are started or stopped together. You use a common instance profile to set parameters for all the components of an instance.
A central R/3 System consists of a single instance providing all the necessary R/3 System services.
Each instance has its own SAP buffer areas.
The message server provides the application servers with a central message service for internal communication (for example, trigger update, request and remove locks, trigger background requests).
The dispatchers for the individual application servers communicate through the message server, which is installed once in each R/3 System (it is configured in the R/3 System profile files).
Presentation servers can also log on to an application server through the message server. This means that you can use the message server performance database for automatic load distribution (logon load balancing).
SAP ABAP Tutorials : Navigation
The SAP R/3 System is a client system. The client concept enables the joint operation, in one system, of several enterprises that are independent of each other in business terms. During each user session you can only access the data of the client selected during the logon.
A client is, in organizational terms, an independent unit in the R/3 System. Each client has its own data environment and therefore its own master data and transaction data, assigned user master records and charts of accounts, and specific customizing parameters.
A user master record linked to the relevant client must be created for users to be able to log on to the system.To protect access, a password is required for logon.The password is hidden as you type (you only see asterisks).SAP systems are available in several languages. Use the Language input field to select the logon language for each session.
Multiple logons are always logged in the system beginning with Release 4.6. This is for security as well as licensing reasons. A warning message appears if the same user attempts to log on twice or more. This message offers three options:
Continue with current logon and end any other logons in the system
Continue with current logon without ending any other logons in the system (logged in system)
Terminate current logon and the screen shot is as shown .
Menu bar: The menus shown here depend on which application you are working in. These menus contain cascading menu options.
Standard toolbar: The icons in the system function bar are available on all R/3 screens. Any icons that you cannot use on a particular screen are dimmed. If you leave the cursor on an icon for a moment, a small flag will appear with the name (or function) of that icon. You will also see the corresponding function key. The application toolbar shows you which functions are available in the current application.
Title bar: The title bar displays your current position and activity in the system.
Check boxes: Checkboxes allow you to select several options simultaneously within a group.
Radio buttons: Radio buttons allow you to select one option only.
Status bar: The status bar displays information on the current system status, for example, warning and error messages.
A tab provides a clearer overview of several information screens.
Options: You can set your font size, list colors, and so on here.
SAP Easy Access is the standard entry screen displayed after logon. Using the menu path Extras® Set start transaction you can select a transaction of your choice to be the default entry screen after logon.
You navigate through the system using a compact tree structure that you can adapt to your own specific requirements. Use the menu path Extras® Settings to change your view of the tree structure. You can use this to display technical names (transaction codes).
Enter a transaction code in the command field:
A transaction code (T-Code) is assigned to each function in R/3 (not each screen).
You can access the assigned transaction code from any screen in the R/3 System.
You can find the transaction code for the function you are working in under the Status option of the System menu.
For example, to display Accounts receivable master data, enter “/n” and the appropriate
transaction code (in this case “/nfd03”).
combination to make the cursor move from one (input) field group to the next. Use TAB to move between fields within a group.
Use F1 for help on fields, menus, functions and messages.
F1 help also provides technical information on the relevant field. This includes, for example, the parameter ID, which you can use to assign values to the field for your user.
Use F4 for information on what values you can enter. You can also access F4 help for a selected field using the button immediately to the right of that field.
If input fields are marked with a small icon with a checkmark, then you can only continue in that application by entering a permitted value.
You can flag many fields in an application to make them either required entry fields or optional entry fields. You can also hide fields using transaction or screen variants or Customizing.
The R/3 System provides comprehensive online help. You can display the help from any screen in the system. You can always request help using the Help menu or using the relevant icon.

The standard SAP screen consists of following elements .
Command field: You can use the command field to go to applications directly by entering the transaction code. You can find the transaction code either in the SAP Easy Access menu tree (see next slide) or in the relevant application under System® Status.Menu bar: The menus shown here depend on which application you are working in. These menus contain cascading menu options.
