Replenishment Planning WVM1

Dear all

We would like to use replenishment Planning (transaction code WVM1) within an S/4 HANA system. We have the same customer number opened for several sales area. The customer is open for several sales area because we have different companies on the same system.

Example:
Customer 2028170 opened for sales area 3010/10/00 = Company I and sales area 3910/10/00 = Company II.

When we use transaction code WVM1 there is an error message "EWT 219 No qunique sales area found for goods recipient 2028170". Unfortunately there is no selection field in the selection screen, where I can enter the desired sales area to use. Is this a restriction within replenishment planning that there is no possibility to use SAP standard within the fact that a customer is opened for more than one sales area? Does anybody already have this situation as well?

I already checked SAP OSS and did not find anything regarding this situation.

Best regards,

Franziska
