SAP APO system is commonly integrated with SAP R/3 or ECC system to get the master data, and planning results are transferred back to the SAP ERP system. The integration between SAP APO and ECC system includes −

 

• Technical integration between systems
• Integration of master and transaction data

Technical Integration Between Systems

To integrate data between SAP R/3 or ECC system to SAP SCM system, you use a Core Interface (CIF) to enable data exchange between the systems. Core Interface provides different integration and data transfer functions.

 

• You can transfer master from SAP ECC system to the SCM system.

   

• When SAP SCM system involves APO, CIF is used to transfer planning results back to ERP.

   

• Different administration tools to manage data transfer between systems.

   

• Support for different source/target systems.

   

To transfer the data between ERP and SCM system, you need to customize CIF settings in both the systems. Customizing CIF depends on the types of source and target system.

 

Customizing CIF Settings in ERP System

To perform integration between two systems, you have to customize the settings in both the systems. Customization of settings is the target system specific or client system dependent. Following settings can be done in the system −

 

Define Logical System and Assign the Logical System to a Client

 

Transaction Code − BD54

 

 

Transaction Code − SCC4

 

 

Define Trusted RFC Connection and Assign Destination to Various Applications

 

Transaction Code − SM59

 

 

Transaction Code − CFC7

 

 

Defining the Target System and Queue Type

 

Transaction Code − CFC1

 

 

Define User Parameters

Transaction Code − CFC2

 

 

Define Filters and Select Size in CIF Settings

 

Transaction Code − CFC3

 

 

Define the Number Ranges for Parallelization

 

Transaction Code − CFC8

 

 

Integration of Master and Transaction Data

You need to transfer the master data and master data changes to the SAP APO system from the transaction system. This data is transferred via the Core Interface.

 

In the SAP APO system, you can check the master data transferred to the APO system.
