Unable to unreserve PO because the distribution quantity billed exceeds distribution quantity ordere

Hello,

We have several (over 1,000) POs that we ultimately would like to finally close; however, they are in a Requires Reapproval status.  When we attempt to unreserve them so we can fix them and then approve them, we encounter the "shipment #1 distribution #1 quantity billed is greater than quantity ordered" error message.

Is there a standard way in which we can fix these POs and then finally close them, or does an SR need to be opened for each one?

Thanks,

Debby
