ACCUMULATED_DAYS is an optional 18-character numeric field that shows all eligible time (in days) ever processed for the employee.  ‘Accum. Days’ are based on the data in the Eligible Element field of the Wage Step Rules [ISRS] form. As pay components are normally in hours this field is populated by determining the ‘Eligible Hours’ and dividing it by the standard hours per day on the group form [IDGR].
