Hi

I have a formula below that works, where its not affected by [Cust Group] selection.

I now want to add to this formula that will also not be affected by [Module] selection.

How do i add this to the formaula.

sum({<[Cust Group] => } if(MonthIndex >= ( vMaxMonthIndex -1)  and Branch='Johannesburg' ,

[Order Quantity Backordered]*

[Component Qty],0))
