3276652 - Deleting a license via T-Code SLICENSE and user SAP* fails with message "Only the administrator is allowed to delete licenses. ..."

The installed system license of your AS ABAP is invalid because the installation or system number has been changed. This situation usually occurs if you are using a system copy.
To install a license key with a new installation number or a new system number, you must delete the old license keys first. Since these old license keys are invalid, you can only log on with the automatic user SAP*.
However, user SAP* is not allowed to delete licenses and you face the following message:

"...
 Only the administrator is allowed
 to delete licenses.
 When the valid system license has
 expired, only the user SAP* can 
 log on to the system. In this case,
 it would be dangerous to delete
 a license.

 This is why the user SAP* is never
 allowed to delete a license.
..."

As result you cannot delete the licenses via T-Code SLICENSE.
