Use
In this step, you define a time schedule for business events.
A time schedule defines the timetable of a business event that comprises a number of days, each day consisting of up to three day segments.
You can use the time schedule to create a schedule model for business event types or an actual schedule for a business event.
Procedure
On the SAP Easy Access screen, in the SAP Standard Menu choose Human Resources ® Training and Events ® Business Events ® Settings ® Current Settings ® Time Schedule. The data screen Change Time Schedule: Overview appears.
If there is no day segment to suit you, choose New Entries and enter a key for the new day segment. Assign a maximum of three time blocks (that do not overlap) to the new day segment. You do so by entering a start and end time for each one. Save your entries.
Result
You have created a time schedule for business events.

You use the same procedure to change an existing schedule.
If you want to change the individual day schedules of the time schedule, select these on the initial screen and choose Day schedules.
