The PORel.DueDate is only needed if the specific release has a different due date than the PO Header.
Maybe try doing it in two steps
Without specifying the PORel.DueDate
Update just the PORel.DueDate (not the Combined update, just the PORel table)
One thing that is a huge Gotcha with DMT. The LineNum you specify isn’t always honored.
If you had a PO with 7 lines, but numbered 1-4, 6-8 (line 5 was deleted for whatever reason), when DMT reads the row with line#6 it creates it as anew line and assigns it to Line 5.
Calvin, do you know if there is a way to get around so that the PO line is imported as 6-8 and skipping the 5 if it is not there? Because I am reimporting PO and Receipt, I want things to line up.
I’ve always just padded the DMT with filler lines, then went back and deleted them (usually with DMT). Do this on Releases too.
Set the PartNumber to something obvious like DMT PADDING, so if you miss one, everyone will know it’s to be ignored. If it is a Release, set the NeedBy date to a specific odd value (like your birthdate).
