I created a Service PR & PO for the same with one line item. After generating the invoice, I tried to increase the PO line item quantity by 10%. But the system did not allow us to change the line item quantity. We received the error message "Materials of Requisition XXXX item 00010 alr. ordered in full" .
However when i logged into SAP using my colleagues ID, i was able to increase the PO line item quantity by 10%.
Could you please tell me whether am i facing this issue due to any missing Role or any confirguration needs to be changed?
Looking forward for your helpful answers.
Thanks in Advance.
