Errors #
If you get the error:
The [DATESCHEMECEASED] must be today or earlier. Please check (7876)
Today referred to in the error is not today’s actual date; it is the pay run date. To correct this error, change the pay run scheduled target date to be today or later (e.g. week-end date or month-end date). Then redo the pay run.
