Deleting personnel numbers in SAP HR

If you have some duplicated, personnel numbers on the system and the data is not complete.

You try to delete these and get the message "record cannot be deleted (time constraint 1)".

The fastest and simplest way to delete employees is to use program RPUDELPN.

Either that or from PA30, click to Utilities -> Delete Personnel Number.

Certain infotypes have the time constraint set so that you cannot delete them which is why it is giving you the message.

To avoid problems, use the above methods.
