Cancelling Approved Records 
Cancelling Approved Records
Use
If you notice that some of your approved data contains errors, you can cancel the records with errors. To ensure that you can still track cancelled records in future, the system does not delete them. Instead it creates a cancellation document that contains the reference to and invalidates the original record.
If your profile settings determine that approved records may not be changed, you also cannot cancel them once they have been approved.
If you change the cell content of an approved record, you are effectively cancelling the original record. The system creates a new record to reflect the changes.
Whilst a record has processing status 10 (In process), you can overwrite its cell content in the time sheet as often as required without cancelling the record.
If your data does not undergo an approval procedure, you can cancel it as soon as it has been released.
