We have developed custom program to print checks on pre-printed stationery. The pre-printed stationery(1st section is payment advice and second section is check) has check numbers on it and we have maintained the same check lot numbers in SAP which gets printed as well for internal control purposes. If the number of invoices run in multiple pages for a single vendor, then SAP would still generate just one check number. However the if the pre-printed stationery runs in multiple pages for the same vendor then multiple checks get used. This scenario is causing inconsistencies between the check numbers in SAP Vs check numbers in pre-printed stationery.
Requirement: If the number of invoices increase by more than 10 (This is the number of invoices that can be incorporated in 1 page) then a seperate check number should be generated in SAP.
