Restrict CATS for employees in one cost center

Dear All,

I have a requirement as below:

Employees are assigned to cost center. I would like to restrict the CATS use per cost center. This means employee in one cost center should not be able to enter the timesheet for employee in other cost center.

In one administrative SAP login/ access, it should be allowed to enter tiemsheet for one cost center only.

Is this possbile? If yes, How?

Regards,

Smile
