FITV travel assistant - buttons Add and Remove Employee

Hi experts,

My client have just implemented FITV in SAP Portal and they are using FITV in Portal for employees, managers and assistants (can book travel expenses for employees).

There are some assistants that are not able to see "Add and Remove Employee" buttons. They have access to Portal specific role for assistant (and backend assistant role SAP_FI_TV_WEB_ASSISTANT) and they are able to see the employee list iview but they don't have any employee on the list and also they can't add any employee as button "Add employee" is not available.

Moreover I have tested on development system: there is a specific (test) user for assistant connected with an employee that is working fine. When I map this employee with my user I am

Do you have any idea if there is any authorization / configuration missing for my user account? or any OM relationship?

Thanks in advance.

Best Regards,

AS
