Hi everybody,
I resolved this case using a Script View.
I had to create 3 Calculation Views:
A: Calculation View Graphical his source is a Analytical View
B: Calculation View Script
C: Calculation View Graphical for realize the Join
First, I created the Calculation View A, where I have the Sales.
After that, create the SQL Script for obtains the aggregated Result from the Sales, for example, to Material Group level. This one is the Result Sales of Calculation View B.
And finally I created other Calculation View Graphical for to make a Join by Material Group between the a Calculation View A and Calculation View B. Into agreggation node I made the column calculated (Sales/Result Sales)*100
Regards!
