DAX - How can I divide each sale with total revenue? See model

[carlenb]

Hi,

I'm trying to create a measure that will calculate divide sales by tota supplier revenue. This will give me a market share we have on that supplier for each here. See my schema below. 

I also have the following graph where I've highlighted the end resultat to add a second line for % market share for eachsupplier. I seems like such an easy measure but I'm still a learner in this. 

Any help on this would be amazing!

Hi @carlenb 

The data model is set up incorrectly

The 3 tables for supplier revenue, do they contain dates and have the same column names and format? In Power Query, I would append all these tables together into one table. I would append as new and untick the enable load on the 3 tables and load the new table into the report. Re create the relationship, but this time instead of having both directions,create a one to many from the Supplier Table to the New Table and Sales 20-22 table.

The same for the Calendar one to many to both other tables on the date columns. 

You can then create this measure to get the % Marketshare

% Marketshare =

VAR _SupRev = SUM(SupplierRevenue[Revenue])
VAR _SalesRev = SUM('Sales 2020-2022'[Total Value])

RETURN
DIVIDE(_SupRev, _SalesRev)

Convert to %

Use the Columns from the Date and Supplier tables in any visual or slicer and then the measure

Thanks
