Has anyone ever successfully added a line in PO31 using add-ins that actually tied to the original PO number and PO line number? I have been able to add the line with all the other relevant data, but for some reason I cannot get the upload to recognize those fields. I am using: f56 PTL-ORIG-PO-NR1, f57 PTL-PRIG-PO-REL1, f58 PTL-ORIG-PO-CODE1, and f59 PTL-ORIG-PO-LN-NBR1.
