Impex import restriction through backoffice

Hi Experts,

We are facing below issue in ImpEx import through backoffice.

We have provided full access to products and categories for "testusergroup". When i am trying to import products and categories using import option from backoffice is working fine but at the same it is allowing me to import pricing, usergroup,employee etc., through backoffice even it doesn't have any access. Can anyone help me how can i restrict ImpEx import.

Thanks, Suersh G. 7013277127.
