I have created a new alv report for sale order statement.The problem is which can be seen in all plants

irespective of the user.Suppose our company has 5 palnt

Plant 1100 to 1500

The problem is suppose a user he has only rights in a prticular plant but he can see all the palnt sale order details

How can we authorize this particular alv report based on the plants
