Summing groups of rows together? DAX formula using PowerPivot?

Question

I am trying to sum up multiple rows in a PowerPivot model but have them grouped:

For instance if there are 20 total rows, Project A, B, C, D, E, F (5 projects - 4 entries per each project.

Is it possible to add up but group them? So for instance: If: Project 1 5 hours Project 1 5 hours Project 1 6 Hours Project 1 3 hours Project 1 5 hours Project 2 5 hours Project 2 5 hours etc.

Is it possible to use DAX (Maybe Summarize?) to add them up but group it so the result would return as: Project 1 = 24 hours (which is all of them added up 5+5+6+3+5) and Project 2 = 10 hours (which is both project 2's added up, 5+5)

and so on and so forth?

I was looking at the =SUMMARIZE and followed the syntax but it would always give me an error/not work how I wanted it to.

Answer 1

Can you please clarify why you need to do this via a DAX calculation? If you added a simple =SUM() calculation and then added Project to your PivotTable, then the context of each of those calculations would automatically result in the answers that you're looking for. Here's an example:

Sample Table

• Table Columns
  • Project
  • Hours

SAMPLE DATA IN TABLE

Project 1,5
Project 1,5
Project 1,6
Project 2,5
Project 2,5
Project 1,3
Project 1,5

Calculated Field : TotalHours:=Sum([Hours])

PivotTable :

Values: TotalHours
Rows: Project (You could also choose a specific project as a filter)

Results :

Project 1: 24
Project 2: 10

In this example, because the context of each cell in which the TotalHours calculated field is used is limited to a single Project, you don't need to do anything special to group them to get the results you're hoping for.

Of course - this is all a moot point if you're trying to use these calculations as an intermediate step...
