Dear Jurgen,
PO quantity is 1 CS and the GR quantity is also 1 CS. There is no open quantity. Also Delivery completed indicator is also set.
Even though user tries to post once again GR, it will not allow to post further GR.
The concern from the user is about the status..
i.e., though user has done GR, but still it is showing as open, and the user is getting confused.
It is happening only with the Purchase orders of which any line item/items are marked for deletion.
If at any time, PO does not have any line item marked for deletion, then the status is fine.
I will look for field help and try to shhare
Regards
Sesha
