Azhar,
Please tell me which option should i make "Forbidden" here?
The business operation that you do not want to allow, RMPO and RMVR, that should suffice the example that you have provided. But you can test with all three RMPH, RMPO and RMRU. In my earlier response I mistakenly added RMNS, apologies.
Please also note, it is not advisable to change the BS22 settings as they represent the standard business transaction sequences. They also get refreshed with system upgrade. You can also use user status functionality available in BS02. You could get enough details and examples of user status BS02 in the forum. You can further try this functionality.
Best Regards,
Rajen
