This operation removes Ignore History Markers or Ignore Timecard Markers for a list of employees. When an Ignore History Marker is removed from an employee record, all Attendance events are processed. When an Ignore Timecard Marker is removed from an employee record, the Attendance Processor no longer ignores Timecard data preceding the Ignore Timecard Marker date.
