Access problem on HR

Hello All,

I have a strange situation.

System : HR

Support package : latest

10 Users have authorization to view master record of all users with the present roles assigned their User Master Record.

1 user has the same roles assigned but not able to see records for any employee.

I have tested on the test box by creating an access similar to production for the user and there he is able to see the employee records.

Your advise will be helpful.
