SAP B1 service layer authorization

Hello, i want to know if we set authorizations in sap b1 fat client to a user, for example i set business partners authorization to "No Authorization" to one of the users, and if i login with that user i am not able to open business partners page, however i also want this authorization to be applied in service layer queries, is it possible?

I tried but it doesn't seem to be working, i just wanted to be sure if i am not doing a wrong thing.

Thanks.
