Essbase formula at aggregated period level

Essbase formula at aggregated period level

Content

Hello,

Is it possible to enter data at base period members(Jan,Feb etc) and calculate using a formula at aggregated period members(Q1,Q2, etc)

Account and period are dense in my database

      Jan     Feb     Mar     Q1

A1 100     200     100     400

A2     .1     .1     .2          .125 (Calculated)

A3 10       20        20     50

In the above example, A2 is an entry field for Base periods, but it should be calculated at aggregated period level.

Please suggest a way to achieve this.

Thanks
