Procedure
Delimit infotype records if you want to bring the validity end date forward, and in so doing, change the validity period.
If, for example, the working time stored for a position has changed, you can delimit the corresponding data record for the Work Schedule infotype and create a new one.
The Maintain <Object> screen appears.
The infotype screen you selected appears.
If more than one infotype record is available, choose Goto Previous record or Next record to select the data record that you want to delimit.
Note that you can no longer edit historically recorded data records.
The Maintain <Object> screen appears.
