How does EWM determine Business Partners?

2530 Views

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.
