Employment and Salary Verification - ESS

Hello SAP Gurus,

We are in ESS BP 50.4 and NW 6.0 with patch 19. We are in SAP R/3 4.7.

Here is an issue:

When I’m trying to use “Employment and Salary Verification” page, it is giving an error “You are not one of the possible agents of the task”, even though we have made assigned agents on task TS01000076 as general task.

Please help.

Thanks
