one of fi user is facing problem when he run fbl5n and go to customer account search by company code,
it gives error no value for this selection
when i use su53 there is giving some
authorization obj. s_project project managment.project authorization
authorization field ACTVT activity
authorizationfield APPl_COMP application componenet ID
authorizationfield PROJECT_ID project name
authorizationfield PROJ_CONF confidential activity flag
Put on trace for your colleague and check out what objects it is calling for him.
Once you are ready with objects, check in auth profile if those are present.
I assume that you both have same set of role menu.
one more idea, Create a test user, just give fbl5n, run it. You would know what objects it is looking for.
