We had a bank transaction post through our 3rd party reconciliation plugin, (Easy e-Bank Rec) with 2 lines, but one of them has a null account number. i think the issue of how this happened lies with the vendor, but i'm not sure how to fix it. We aren't able to do anything to that posted voucher (correct, etc)
I think deleting the entry in SQL and creating a new/correct one may cause other issues since that bank rec entry will have no GL counterpart.
It seems like updating that particular distribution line in the SQL table with the right ACTINDX value is probably the best solution? but aside from running reconcile in GP, i'm not sure if anything else needs to be done.
