We just upgraded to Lawson 10 this past weekend. We are getting an error message on our MA531 report that reads: "Detail record is required for tracked inventory items; Item 9913367" We have only been getting this error message on our large EDI PO's. The smaller PO's seem to come through okay. This message in only the last line of the PO, no other lines. If we take off the line on the PO, receive the PO and run the MA531 again, we get the same error message, now on the new last line of the PO. Anyone else ever have this error message with the same conditions? Any suggestions?
