Check to be sure DMS of payment applier program is in sync with the program for any new changes. Also be sure the proper key values are being passed to the program.” refer to problems on the Item Type setup. Make sure Charge List and Payment Overall Priority fields are populated. Make sure that if Payment Priority flag is checked, that there is a payment priority value, too.
