Maintain Availabilities Based on Fixed Times 
Use
Use this availability variant if an employee has availability duty for a specific interval of time.
This particular variant is intended primarily to record periods of availability that are outside the employee’s planned working time specified in the daily work schedule.
For flextime daily work schedules, the period of time outside the planned working time should also be outside the normal working time. If availability periods overlap with times stipulated in the employee’s daily work schedule, the system displays a warning, but still allows you to create the record.
On-Call Duty
On-call duty includes a special feature in the SAP Human Resources component. The times specified are not interpreted as an interval for on-call duty, but indicate the start and end times of a complete on-call record. This means that it is quick and easy to enter data on availability duty that extends over an entire weekend, for instance.

For example, an employee has on-call duty from Friday, December 8, 1997, to Monday, December 11, 1997, at 8:00 a.m. Create the following record to represent this information:

If you want to create an On-call record for a specific time interval, you can do so in one of two ways:
·
Create an availability record for each day·
Use a daily work schedule or work schedule rule that was created to reflect this type of on-call duty.For more information on Activity Allocation and Cost Assignment, see
