Field based authorization in Query SQ01

Hi SAP Gurus

I have made a query via SQ01 . Now i have assigned two users to execute the query but both these users are from different companies and able to execute the query for another company also which is not correct .

What i want to do is to restrict company code in accordance to user id of the respective person .

We do not have an abapper currently ? Can anyone help me with this ?
