PowerPivot DAX formula to sum on dimension attribute

Question

I am trying to do some calculations in a PowerPivot cube that contains data from a time registration system.
I have a table called "Registered Hours" that is connected to a table called "Resource" that again is connected to a table called "Department". I'm trying to build a calculation in the "Registered Hours" table that sums up per Department. The purpose is to compare a resource values against the sum of the entire department.
I've tried implementing the calculation using ALLEXCEPT (from this SO: How to SUM a Column based on another column in DAX Powerpivot ):

CALCULATE([Registered Days];  ALLEXCEPT(Resource;'Department'[Department Name]))

This does work, as long as I have the "Department Name" in my pivot table. If I build a pivot table that only has the "Resource Name" (from "Resource" table) on rows this calculation returns the same for all rows. If I add "Department Name" to rows, the calculation works as intended.

Answer 1

I suggest creating a calculated field (measure) instead of a calculated column.

It is import to understand the context. If you are not adding a column or row to your pivot table, it will not include it in the context and the calculation for TOTAL will not take that information into account. So, if you want to see the total hours per department and resource, both resource and department must be in the pivot table and both columns should be in the ALL EXCEPT function.
