Hello Martin.
Definitely the SAP note implementation solves the authority check incident. CAT_PING Function Module and AUTHORITY-CHECK statements for the OBJNAME followed with DUMMY is flawlessly working as a wildcard entry.
I was in debug mode and find out that the authority check is being executed for transaction SECATT thru ABAP program: SAPLECATT_MAIN , it makes a dynamic call to SAPLECATT_EXECUTE at include LECATT_EXECUTEI03; MODULE ecatt_execute_active_tab_get, this is the moment when CAT_PING function module is invoked. I will keep investigating the exact point because the function module is not explicitly called.
I appreciate this valuable information.
Best regards,
