SAP APO Interview Questions and Answers

What is Release Profile?
Release Profile is used to release timeseries data from DP to SNP/PPDS. You need to define the DP Planning Area and timeseries keyfigure the data in which is released and the SNP Category Type (typically FA) to which data is released. You may maintain a Daily Buckets Profile it will define the number of working days (working days determined based on Shipping Calendar maintained for the location master) starting on and from the From Date if released online/ interactively or that many workdays of the planning horizon when release is carried out in background. The Period Split (blank, 1 and 2) field in the SNP2 tab of location-product master determines how demand plan is released to SNP from DP (how bucketed data is disaggregated to the workdays).
What is the usage of Period Factor?
Period Factor maintained in the SNP PPM or Transportation Lane determines the Availability Date of a Receipt element within a time bucket (period). The system determines the exact availability date/time of the receipt elements within a period, by adding a time interval (that it gets by multiplying the period factor with the period length) to the start time of the period. You can enter a factor between 0 and 1, where 0 is the start of the period, 0.5 the middle, and 1 the end of the period. When calculating the availability date/time, the system takes into consideration all weekdays, meaning that it does not take into consideration any days that have been defined as non-workdays in the calendars.
Period Factor used is .71 = 7x0.71 = 4.97 or 5 days from ptimizer of weekly bucket resulting in a Friday.
If Period Factor is not maintained in PPM or Transportation Lane then the User Period Factor indicator and the Period Factor value maintained in the Lot Size tab of the location-product combination is used. If this is not maintained a default value of 0.5 is used.

SAP SCM 4.1 is the new available Supply Chain Management Solution offered by SAP. The SAP SCM 4.1 System includes SAP APO 4.1 (Advanced Planning and Optimization), SAP ICH 4.1 (Inventory Collaboration Hub) and SAP EM 4.1 (Event Management).
How about the architecture of SAP SCM 4.1?
SAP SCM 4.1 is based on the SAP Web Application Server 6.40. All SAP SCM 4.1 Architecture Components can be installed on one hardware server, as long as this server is sized for all used application components.
What does APO mean?
SAP APO stands for SAP Advanced Planning and Optimization and is the planning component within the mySAP SCM solution.
Can SAP APO be used as a stand-alone solution?
No, SAP APO always requires a backend ERP system for execution functions. In most cases, the backend system is an SAP R/3 system.
Can SAP APO and SAP R/3 be installed on the same server and use the same database?
No, SAP APO requires a separate server. The actual size of the SAP APO system may vary and depends on the data volume to be processed. You can find more details on this subject under the alias /sizing on the SAP Service Marketplace (//http:/service.sap.com).
How does SAP R/3 communicate with SAP APO?
Through the APO Core Interface (CIF) which supplies SAP APO with master and transaction data in real time. CIF is delivered through the R/3 Plug-In, which is something you have to install in your SAP R/3 system. This is the same Plug-In that you need for connecting a BW or a CRM system.
What about the exchange of data between the two systems?
With SAP APO you have a real-time integration to SAP R/3. The minute you change something in one system, it is immediately being transferred to the other and vice versa. And that goes for all data, be it a sales order, a production order or a purchase order. You do not have to perform any batch jobs for transferring data between the systems.
OK, SAP APO is a separate system. Do I have to maintain the master data twice?
No. You create and change master data exclusively in SAP R/3. If you want to work with SAP APO, you need to transfer the master data from the SAP R/3 system.
Depending on the scenario you want to use in SAP APO, you may have to enhance the transferred data with SAP APO specific settings, which are not relevant to SAP R/3.
What is an easy, cost efficient way of installing some standard SAP APO scenarios?
The answer is: SAP Best Practices for Supply Chain Management. Choose one or more of the mySAP SCM business scenarios that SAP Best Practices for SCM provide.
