Hi Barb9:

To elaborate on Support's answer, a cheque stub only has space for a limited number of invoices (let's say 10). So if you print a cheque that pays 11 to 20 invoices, a 2nd cheque is required. Only the final cheque can be cashed, the others are marked as "Void" on their face. Payables knows this and keeps track of the cheques numbers for audit purposes.

From your description everything appears normal except for 2 things.

1) You don't print cheques. Yet the only way Payables will assign cheque numbers as described is if cheques are printed. Do you print onto blank paper?

2) Look at the cheque specification/layout. It has a setting that controls how many invoice lines will appear on an advice. The usual number is somewhere between 10 and 13.
