How does EWM determine Business Partners?

Hello Experts,

currently we are using the same number range for our vendors and customers in our ERP system. When distributing them to EWM, we add prefix C to customer and V to vendor number to avoid conflicts.

Examples:

ERP vendor no. 2774382 gets EWM business partner no. V2774382

ERP customer no. 4546528 gets EWM business partner no. C4546528

Now, we are planning to move our ERP system to S/4 HANA where customer and vendor masters have to be migrated into business partners there. Due to other connected systems, EWM nomenclature cannot be used for ERP so that we will get new BP numbers in EWM.

When cutting over to S/4 HANA, we would deactivate logic of prefixing BP numbers in EWM so that we would use the same partner number as in ERP in order to have same numbering in all our systems. EWM would get same BP data from ERP but with different numbers, so they would exist twice: Once with prefix (C or V) and once without.

Basically each customer in EWM is linked to its ERP partner via ID with ID type CRM002, vendors are using ID type CRM004.

How does EWM determine the correct BP if two BP´s exist with same ID´s?

Would we run into trouble then? If yes, how else we could solve this issue?

Kind regards,

Peter.

    Hi Peter,

    I guess, you can achieve to avoid duplicating the BPs through ' business system group' concept.

    If you maintain and assign the new business system group in EWM  system for your ERP, system considers the new BSG only for identifying the new master data.

    But, old data ( with prefixes C & V ) remains in the system and until unless do the archiving.

    for further explanation , please go through the IMG documentation in the below path.

      Hello C K Reddy,

      I am not quite sure what you mean but I think we do not have to consider product masters as we will not change material numbering for S/4 HANA.

      Kind regards,

      Peter.

    Hello Peter,

    you can use business partner ID mapping. You can find the documentation in the application help (help.sap.com/ewm) at Warehouse Structure -> EWM-Specific Master Data Settings -> Business Parner ID Mapping.

    Hi,

    "How does EWM determine the correct BP if two BP´s exist with same ID´s?"

    At first glance I would say that they are not really the same, because the "Responsible Institution", which is the logical system from which the BP comes (or which connects it to this role in that system) for surely will be another one, when you switch from ERP to S/4 HANA?

    If not, I am not even sure what would happen in the moment you CIF the BPs?
