Problem with SAP_ALL regeneration

Hello

I have a problem with SAP_ALL. Somebody have regenerated this profile so now I have all the new authorization object in SAP_ALL. I tried to modify the &_SAP_ALL_16 (it's the profile which contains the new authorization object in the SAP_ALL profile) in order to delete the new authorization object.

I have a message "Generated profiles can only be displayed".

Somebody can help me please ?

Thanks for your help.
