Help Modifying a Formula after adding RLS

[roguetrader87]

Hello

I recently added RLS security to my Power BI report which resulted in some of my visuals to no longer work. Could anyone take a look and my formula and see what I need to modify?

Latest Sales Open Orders = CALCULATE(SUM('Open Orders'[Open Order Amt]),LASTDATE('Measure'[Date]),'Open Orders'[Category] IN VALUES(Brands[Brands]), 'Open Orders'[Ship State] IN VALUES(Users[State]))

The error in question I am getting is:

Why did I not get this error before but am now?
