We have a few vendors that when they send the invoice via EDI (810) the line numbers are not correct. For instance on the PO the line number is 3, but in the 810 it is 003000. This then kicks out in MA540 as an error because it doesn't match. Besides contacting the vendor to have them correct this has anybody come up with a solution for this? We tried not mapping the line number by using the <TPID>_I_810_LINENUMBERS , but this still causes an issue because then the AP clerk has to enter the line numbers in. Thank you.
