Is either batch number 178 or 179 not posted? Your Crystal report should not include batches that have not been posted.

Both batches have been posted successfully

What report is that? It doesn't appear to be the stock AP Aged Payables. (The fields are out of vertical alignment.)

Also, check what AP Vendors > Vendor Activity says.

Bone stock report as far as I know

I will check the activity report

If both batches are posted, and both those entries still show in the APIBH, the system somehow allowed a duplicate to be posted. You should reverse one of them (with either a DN or adjustment).

The duplicate shows up in Vendor Activity too?

If by "bone stock" you mean "customized to add the PO number field" then I believe you. :)

It only appears once in the Vendor activity screen. As I had said it was not posted in the original batch but was posted from the resulting error batch so the amounts in the system are correct, no adjustment is needed. However, I am looking into that PO# number field customization now that you have nicely pointed that out. Might be sneaking in from that

Yes, the PO number is probably the source of the duplication. Check the joins on the Crystal report. Or get the PO number via a subreport instead. Best of luck!
