Can a Category member be created to calculate Budget vs. Actual for $s and for as a percentage?

Hi BPC Community,

Note: For SAP BPC 7.5 Microsoft

Can a Category member be created to calculate Budget vs. Actual for $s and for as a percentage? I'm thinking that the two new category members will be calculations based on Budget and Actual. For Budget vs. Actuals in $s = BvA$ [formula: Budget-Actual]. And as a percentage BvA% [formula: ( | (B - A) | / ((B + A)/2) ) * 100].

I know that only alphanumerics can only be used in member names. I'll make up correct names later.

Thanks! Barry
