Hi Perrine,
Authorization profile few limitations:
1. The control parameters should exist when you create an event handler.
2. You have to assign to event handler.
Let's follow these steps:
1. Create Authorization profile parameters in IMG
2. Go to user role in SUIM
. Go to Authorization tab -> Display Authorization -> Event Management -> Event Handler Authorization -> Give Parameter name in authorization object field "X_EM_EH"
3. Assign Parameter name as "A" in Parameter Value of Length 255
Other option:
Implement in BADI /SAPTRX/BADI_EH_S-AFTER_GET_DATA_DISP what to display to users maintain custom table and logic defined.
