Summarization of a higher dimension in a Pivot Table with calculated dimensions and without using AGGR

[#1]

Hello experts!

I have a simple question...

In a Pivot Table I have Dimensions and Calculated Dimensions:

Yellow: Dimensions.

White: Calculated Dimensions.

Green: Expression.

The calculated dimension is the sum of the previous dimension:

DC GRUPO SUB CANAL:

AGGR(SUM(Units), CANAL, GRUPO SUB CANAL)

I need an expression that makes the sum of Units of previous dimension, in this case the sum of Units grouped by GRUPO SUB CANAL. It is possible to make a expression of previous dimension in a Pivot Table with dimensions calculated without using AGGR? Something like that: SUM(TOTAL<Dimensións, Calculated Dimensions>Units)

Thanks a lot!!!
