Hi
We have a current integration solution to our APO ( SCM 4.0 )in which a legacy ERP system generates files in specific formats for master data feeds ( products, bill of materials, hierarchy etc ) . In APO, an info source has been configured to take in these files and then load these into z* infocubes. ( RSA1 setup ) . Then a std SAP program is scheduled to load the contents of the infocube into live cache.
Legacy system --> Master data Files --> InfoSource --> Custom Infocube --> SAP std program --> Live Cache
APO is being used for Demand planning and sales forecast is the output of the planning process with the foreacast being fed back to the Legacy system.
Now, the legacy system is replaced with SAP R/3 ( ECC 5.0 ) and we intend to use CIF ( core interface ) to integrate R3 with APO. I read in the SAP help documentation of CIF - that the setup of CIF - passes data back and forthe between R3 and APO in real time basis. So, with this setup,
1) Will the master data in this real time transfer go through the info cubes or go directly to the live cache of APO from R3 .
which one of these is a viable data flow using CIF
R3 -->Master data through CIF --> Infosource --> Custom Infocube -->SAP std program -->Live Cache
or
R3 -->Master data through CIF --> APO Live Cache
2) Can the data from R3 using CIF - be loaded into the custom info cube - so that the downstream process can still remain the same ? ( instead of loading directly into Live cache )
Any thoughts, pointers on the challenges that might face when replacing the existing solution with the CIF based integration are also welcome.
