You want to delete old spool requests from the database at regular intervals. You can use the background deletion to do this.
As deleting in the background affects performance, you should schedule it either during the night or at the weekend.
You require appropriate administrator authorizations.
Execute report RSPO1041 in the background (SE38).
When deleting in the background, spool data that has errors or is obsolete is also be deleted from the TemSe data store.
