Hello,
We have the following scenario of 2 ERP systems being integrated to a single APO system, the scenario details are as follows:
System Logical system Business System Group
ERP1 ERP1CLNT ERP1BSG
ERP2 ERP2CLNT ERP2BSG
APO3 APO3CLNT APO3BSG
We will looking at mapping materials from ERP1 and ERP2, this is the statement (SAP refer to Scenario 2) were Product in ERP1 = A and ERP2 = B and in APO3 = A (this is the screw and hammer statement against the Business System Group config documents).
So from my understanding we have to define a parent ERP system for the Master Data (Material Masters) this ERP system is then linked via the same Business System Group being assigned to the parent ERP system and the APO system as bellow:
System Logical system Business System Group
ERP1 ERP1CLNT ERP1BSG
ERP2 ERP2CLNT ERP2BSG
APO3 APO3CLNT ERP1BSG
I understand from reading the SAP documents that we will have to utilize the APOCF005 BAdI.
My first question is assigning the ERP1 and APO3 to the same business system group, does this mean that we will have to maintain all of the Material Masters from ERP2 system (due to the fact that ERP1 has now become our parent master data system?
The second question is that my understanding that the 2 main tables that are being checked/ validated is the /SAPAPO/MATKEY and /SAPAPO/MATMAP, so if ALL the materials are being maintained in the parent data system (ERP1) the /SAPAPO/MATKEY table would have a single entry for each external (ERP1) material number and a UID.
Would this mean that in the /SAPAPO/MATMAP table when I first integrate from ERP1 we would see 1 entry (with the BSG and logical system), if I then integrated from ERP2 I would see a second entry with the same material number and logical system but a different BSG?
External Number BSG MATID MATNR Logical System
Product A ERP1BSG APO12345 Product A ERP1CLNT
Product B ERP2BSG APO12345 Product A ERP1CLNT
Thanks in advance,
