When i'm trying apply docs
I believe that means the record is missing from the APPYM table. (You can verify this by going to Vendor Activity and seeing if you can find the payment on the Payments tab.)
I've had to look at a similar record and add this payment record manually to the table. (More details about the missing payment record can be found in the Payment Entry screen and there will be a matching record in the BKTRAND too.)
Contact your business partner for assistance. Or Musick International can repair. (Or message me and I can help.)
Backup first!!
Thanks so much
