It is not possible to update the service rendered date in the customer project sales orders / billing documents.
"Image/data in this KBA is from SAP internal systems, sample data, or demo systems. Any resemblance to real data is purely coincidental."
Environment
-
SAP ERP Project System (PS)
- SAP S/4HANA, cloud edition
Reproducing the Issue
-
Create Debit memo request (DMR) by editing customer project, with keeping Service date blank.
- Open the Debit memo request, service rendered date is filled and cannot be changed.
Cause
This is designed behavior.
Resolution
When you use the system automatic to create billing proposals which afterwards can be billed, the billing proposals will use the period (month) end date as relevant date.
