Why can a user modify a PO with Closed Status?
We have an issue when our user who inadvertently modified a PO that has been Closed; why can a user modify a PO that has already been closed? To make the matter worse, the PO has been received, invoiced, paid and posted into the GL from the previous month. It is happening in 11i, and I am not sure if the same thing will happen in R12, in which we are upgrading into right now.
The PO modification happened in the Shipments form, where the user tried to change the price for reason I don't know. It now requires re-approval, but since we have a Tolerance limit, it will not allow the Buyer to approve it. The solution I am testing is to perform a data fix in the PO_LINE_LOCATIONS_ALL setting the Quantity back to its original value. This somehow works with additional step in the PO Form. Will this not affect AP and GL? In the future, how can this be prevented?
