If you click on the RC button (PO Receipts) in IN-A (EVO), you get a cannot find specified file message for UDF10.SCR. The grid does show up minimized, so you can restore it to see the results.  If you close the grid and then try it again, you get an access violation error and have to go to task manager to shut down EVO.

Fully verified - error happens in either version of T7 - does not happen in T6 or BKINA

A User Defined Function was inadvertently left in the grid that went out in the post that links the PO Receiver to the AP Invoice number.  You can either go to Queries, SU-A, open the PO_HST_LINES grid and delete the last entry which is the UDF10() or I can send you the UDF10.SRC that it is looking for.  Make sure you use the dlete key on the keyboard and not the DELETE button because the DELETE button will delete the entire grid, not the specific entry.
