Thanks all for your inputs,
The actual issue is 'during PO creation we are updating CCTR and WBS info but system is not issuing any error on CCTR+WBS combination' however when we do a MIGO with reference to the PO, system issues below error message
Creating PO with 'Account assignment category' as 'K-Cost centre' and adding CCTR and WBS in the Acc.Assignment tab
Would like to understand, if we have any setting to activate, to get the same error at the time of PO itself?
Here is the Error message from SAP
Cost center not allowed on non-statistical WBS-element posting
Message no. ZA002
Diagnosis
It is not allowed to enter cost center when posting to a non-statistical WBS-element.
System Response
The posting can not be made.
Procedure
Enter blank cost center or enter a statistical WBS-element. If the message came as a result of a goods receipt against a purchase order the account assignment on the purchase order must be changed.
Thanks in advance
