PO Receipt Transactions Not Capturing in the WIP Capture

We are on version 10.2.500.2

Every month we have a handful of PO receipts that will not get captured on the Inventory WIP capture.
Its as if one side of the GL transaction happened in 1 day and the other side on another day.

Up until now, we were able to adjust the PO receipt date to match the date the invoice was entered (Not sure why that would work), and the WIP capture will balance for the day and post.

Now we have one transaction, that we cannot get it to post no matter what day we change the PO receipt to. The receipt has been invoiced so we cannot delete the receipt and start all over.

Has anyone else experienced this? Do you know what caused it and how to fix it?

I recently had a similar problem on 2 PUR-UKN transactions. Only half would appear in INV WIP Recon report (IWR - which uses the same posting rules as Capture COS).

The IWR summary would show different totals for debits and credits.

Once we found the transaction, we reopened the PO , updated the GL acct, then re-closed the PO. Then the IWR would show both halves of the transaction and the totals would balance.
