PowerBI - Comparing two similar sets of data (Many to Many)
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am trying to compare to sets of data that are very similar. I have done a bridge relation and used M:M relationship on PowerBI but I am still not getting the result I want.
Here is an example of the data:
Dataset 1
Name | Service | Usage
A | 1 | 10
A | 2 | 20
B | 1 | 10
B | 2 | 10
C | 1 | 20
C | 2 | 10
Dataset 2
Name | Service | Usage
A | 1 | 40
A | 2 | 20
B | 1 | 40
B | 2 | 10
C | 1 | 40
C | 2 | 10
Desired output
Name | Service | Usage 1 | Usage 2
A | 1 | 10 | 40
A | 2 | 20 | 20
B | 1 | 10 | 40
B | 2 | 10 | 10
C | 1 | 20 | 40
C | 2 | 10 | 10
Is this possible in PowerBI?

Instead of a bridge, create 2 dimensions: one with names. and one with services, and connect them to both tables (as 1:M relations). Then you will be able to drill across easily.

One approach (as suggested in comments), is to separate the distinct Name and Service values into separate dimension tables, in the query editor:
Names:
= Table.FromList(List.Distinct(List.Combine({#"Dataset 1"[Name], #"Dataset 2"[Name]})),Splitter.SplitByNothing(),{"Name"})
Services:
= Table.FromList(List.Distinct(List.Combine({#"Dataset 1"[Service], #"Dataset 2"[Service]})),Splitter.SplitByNothing(),{"Service"})
Create the DAX measures you want:
Usage 1 = SUM ( 'Dataset 1'[Usage] )
Usage 2 = SUM ( 'Dataset 2'[Usage] )
Now create relationships between the fact tables (Dataset 1, Dataset 2) and the dimension tables (Names, Services):
Then simply layout the visual as required:

Another approach may be to combine your dataset fact tables into one table, with an added "dataset" column:
Create your "combined" table in the query editor.
Combined Table:
= Table.Combine({Table.AddColumn(#"Dataset 1", "Dataset", each "Dataset 1", type text), Table.AddColumn(#"Dataset 2", "Dataset", each "Dataset 2", type text)})
Now use this table as your single source - either with a crosstab visual:
Or by adding separate measure for each dataset:
Usage 1 = CALCULATE ( SUM('Combined Data'[Usage]), 'Combined Data'[Dataset] = "Dataset 1" )
Usage 2 = CALCULATE ( SUM('Combined Data'[Usage]), 'Combined Data'[Dataset] = "Dataset 2" )

Instead of a bridge, create 2 dimensions: one with names. and one with services, and connect them to both tables (as 1:M relations). Then you will be able to drill across easily.
