Connecting 2 ecc systems with 1 APO system

Hi,

In our scenario we have 2 ECC systems to be linked to 1 APO system. I need suggestions on following points?

1   For this we have to define separate Business system groups for each of the ECC Systems. Can we assign the APO Logical system to any of the Business system groups or some specific logic need to be practiced? What should be the criteria for doing this?

2  If we are planning to do some developments in the CIF, what special precautions need to be taken in this scenario?

regards,

Mohit

    Mohit,

    For question 1: You need to ensure the master data in both ECC systems is different and there is no overlap.  You need to assign a unique logical system to each ECC system and BSG in APO since APO will need to send the relevant info back to the correct system where the master data resides.This includes SM59 connection information and all queue configuration.

    For question 2: You'd have to be more specific about what developments you are doing in the CIF. If the CIF code resides in ECC, you probably would not need to be concerned with the other Logical System. If it is in APO, that would apply.

    There are also considerations regarding FI/CO updates and other things as this is a complex undertaking.

    Regards,

    • Hi Mohit,

      As long as there is no conflict, you can assign all 3 systems to one BSG.

      For example, you have different SKUs but represented by same number or same SKU and number in both the systems, then it is required to go for 2 different BSG with APO assigned to one of the BSGs.

      BSG1 - APO, ECC1

      BSG2 - ECC2

      Otherwise, if you have different master data in the two systems, then go for one BSG.

      BSG1 - APO, ECC1, ECC2

      Thanks,

    Hi Mohit,

    For your point #1, I would like to quote the SAP recommendation.

    If you create master data in the SCM system, we recommend that you assign this system to the same BSG as that used for the logical systems that contain the master data server. Only then can preliminary maintenance of the master data be carried out in the SCM system.

    With respect to point #2, ensure that you have unique representation of data especially the number ranges of different objects and maintain the mapping information appropriately. Please check the following link for details on mapping

    http://help.sap.com/saphelp_SCM700_ehp02/helpdata/en/7d/d977377fae0261e10000009b38f842/frameset.htm

    Under mapping, you can see 2 subsections on user exits and mapping information.

    I hope you may get some more valuable information from the community.

    Thanks,

    Rajesh
