Cube views row calculation

[STDN]

Hi All,

I need to calculate the base members and roll up to Total member as shown in the below picture I tried using GetDataCell formula but am getting error, can anyone suggest how to do that.

Please find the below snaps for your reference. Thanks in Advance.

The easiest way to accomplish (and maintain) adding/subtracting of members is to create a parent in the dimension library and set the required aggregation weight on each child.
