Hi, I have an opportunity table which has customer industry and opportunity industry. So I concatenate this two type industry into one table and mapping with the Oppt master table. The structure is as follow. But, when I grant the access to the user. User has three fields to limit the access that Territory/ Branch/Industry. For Territory and Branch mapping with the oppt. master table and industry mapping with the industry table. Pls see the red one. Actually, It will be a loop. But, it won't report the loop issue. Does it influence the data?
