Maintain Substitutions Based on Daily Work Schedules 
Use
Use this function to record changes to an employee’s planned working time that occur at short notice, and involve a full day. These changes to planned working time might involve the following:

For example, the daily work schedules "Early shift" and "Late shift" are already defined in your enterprise. You require a substitution for the late shift on January 21, 1997. You choose an employee who, according to his or her daily work schedule, is assigned to the early shift on January 21, 1997. If you assign the late shift to this employee, the system overwrites the employee’s original planned working time for the day (early shift).
Result:

You are not limited to only the break times specified in a daily work schedule. You can also specify break times that are independent of daily work schedules.
Procedure
The Substitutions screen appears in the processing mode you have selected.

If the employee is to work according to another
Daily Work Schedule Variant, you only have to complete the Daily work schedule variant field. The system then automatically assigns the appropriate daily work schedule.
By changing the day type, you can create a substitution record for a public holiday. To do this, overwrite the entry BLANK in the Day type field with a 0 (work/paid).
Result
You have now maintained a substitution based on a daily work schedule.
