Frequently asked Questions about mySAP SCM and SAP APO
1. Which are the components of the new mySAP SCM Solution?
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).
2. 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
3. What does APO mean?
SAP APO stands for SAP Advanced Planning and Optimization and is the planning component within the
mySAP SCM solution.
4. 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.
5. 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).
6. 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.
7. 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.
8. 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.
9. What is an easy, cost efficient way of installing some standard SAP APO scenarios?

SCM business scenarios that SAP Best Practices for SCM provide.
