How to add another security role to another table using a virtual column?

[Tiger1]

Can I build a security role like this:

Where [Customer_Name] is a virtual column?

If not, how can I accomplish this?

Yes and it seems you have already implemented it.  Are you having issues?

When I try to change to a virtual column - where I circled above - it gives me an error.

Oh ok,  I hope you figure it out!

Anyone have any suggestions?
