Hi Deepak
In SU01 - does the profiles tab contain the corresponding generated profile for the role that you did user compare for?
For tables - you can look at the AGR_USERS (for role - ensure the assignments are within validity date); USR04 will have an entry for the user with all profiles assigned; AGR_1016 will give your role to profile mapping; USRBF* is the user buffer; UST04/UST12 will give more profile and user information.
What does it look like for one user when you go into SU56 - if you expand out their authorisations for the object do you see the values? What value do you have for auth/new_buffering (assume 4)?
Is this for a small group of users or for all users? If a small number, do the users have a large number of roles assigned? Is there a chance you have user buffer overflow from too many profiles assigned?
