Execute a Delete Program for Work Centers (PP-BD-WKC) 
If the delete program is not automatically triggered after archiving work centers, you can delete the work centers after the completion of archiving.
To delete work centers from the database, proceed as follows:
The initial screen for archive management is then displayed.
The Archive Management dialog box appears. Execute Delete Program.
You reach a dialog box that displays all of the archiving runs that exist for archiving object PP_WKC. As a rule, this is the last archiving run that you carried out.
You see all archiving runs that have not yet been processed along with their archive files. Select the desired archive files and press Continue.
The selected work centers are then deleted in the background on the start date. When carrying out the deletion program the system generates a
Standard log.
