Message type: E = Error
Message class:  HRTIM00REC - HR Messages: Time Recording 
Message number: 012
Message text: Only records of less than one day allowed for attendance/absence type &
According to the Customizing settings, the attendance/absence &V1&
permits only partial-day records, that is, attendances/absences that do
not span an entire workday, such as a doctor's appointment.
The system recognizes partial-day attendances and absences from the fact
that the number of payroll hours is less than the number of planned
hours of the work schedule variant <ZH>applying to that day</>.
Partial-day absences (for example, with clock times) entered for a
<zh>non-working day</> are automatically evaluated as whole-day absences
since the number of planned hours for that day is zero. You therefore
cannot save the current infotype record, because in this case the number
of payroll hours is not less than the number of planned working hours of
the applicable work schedule.
Check the Customizing settings for the relevant attendance or absence
and for partial-day records to check whether the day has a work schedule
has zero planned working hours.
