I have discovered an item that was paid is still on my A/P aging report. I don't know why -- I've been in maintain database & the check is listed in BKAPINVT and I did change the "amt rem" to 0 for the invoice line but the item persists on the A/P report.  It does not show as an open item for AP-F or in the vendor stats.   ???

Closing a PO will do nothing to the aging.  Look at the BKAPCHKH (payment history) file - for some reason, the aging is not attaching the payment to the invoice.

Thanks -- I took another look & figured out the problem. I had changed the invoice date elsewhere & the reference # wasn't matching up.  Problem solved!
