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.

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?

Hello Jürgen,
I assume S/4 HANA will remain the same responsible institution as ERP is migrated and not built as a second new system.
But in this case it could be a good idea to change it manually to force separation of new S/4 HANA from old ERP business partners like suggested by C K Reddy before.
Kind regards,
Peter.
Hi,
yes, of course it depends how you migrate to S/4 HANA. As described here (https://websmp207.sap-ag.de/~sapidp/012002523100011787552015E.pdf) you could indeed do a technical upgrade and in that case the institution would not necessarily change. Then I would first check what happens when you CIF your new customers and vendors.

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.

Katrin
