Cost assignment validation in OB28
We have a validation implemented in OB28 for a cost center and G/L account.
The validation gets triggered when the Goods recipt document is Posted/saved and we get the error message correctly.
But the same does not trigger when a 'Check' is done.
The problem we are facing is when the PO is created the system allows the user to create the PO even though the cost assignment is wrong. and when the user tries to post a GR it fails due to the validation.
Is there a way to trigger the validation in OB28 during the PO creation too?
Any input on this will will be appreciated.
