Calculate Variance Between Two Columns in Matrix Visual

[mcmullenrich]

I have two fact tables: f_scripts and f_rebates. Each has a quantity column showing sum of units by date (I also have them linked to a calendar table). I'm trying to create a matrix visual showing the number of units by product from f_scripts in one column and the same thing from f_rebates in the next column (I've accomplished this part). The last part is to create a column showing the delta between the two.

If it's helpful, I could try to create a dummy file to share, but the live file has a ton of sensitive info in it.

Hi @vojtechsima. Here is a snapshot of the visual as it stands now. The two columns shown come from different tables. I'd like to have a column to the right of "Purchased" showing [Purchased] - [Pharmacy]. This visual is controlled by a Month Year dropdown slicer which comes from my calendar table.

HI @mcmullenrich,

What type of aggregate that you want to apply to these grouped ranges of records? Can you please share some more detail?

Here is a sample measure formaul about average of records based on current hierarchy group.

formula =
CALCULATE (
    AVERAGE ( Table[Purchased] ),
    ALLSELECTED ( Table ),
    VALUES ( Table[Common Drag Name] ),
    VALUES ( Table[Pharmacy] )
)

Hi,
@mcmullenrich please share a dummy copyable dataset of your data.

Hi, @mcmullenrich 
If you could share some sample data or help me picture how exactly the delta should be shown (absolute, relative etc.) 
Thank you
