You enter the check lot number as a parameter for the print program RFFOUS_C or define an appropriate variant for this program. The check print program determines the next free check number and stores the assignment of payment document number to check number or of check number to payroll results (in the case of payment runs in Human Resources (HR)).

A next lot can be entered in Interval Maintenance. The print program is then able to determine which check lot is to be printed next. This means that you do not have to change the variant when a check lot is used up.

The check register file records the data resulting from the print run, and the check number status is updated automatically by the print program.
