Column Comparison - Workaround - Manage Relationship

Hello, I am trying to compare two columns in separate tables. Here is the story:

 

Table 1: Demand Seg - Is the master list of all parts we manufacture with.

 

Table 2: Stocking Report - Is the master list of all the parts we have suppliers stock for us.

 

I want to compare the two as a pie chart to see what items of ALL items we use, are stocked.

 

Here is the caveot I can only DirectQuery the Demand Seg, but I am importing the stocking report.

 

I simply want to have a table and a pie chart to tell me what items are stocked and what are not, but I receive this error:

 

Here are my relationships to prove it, does anyone know a workaround?

A roadblock is that I cannot adjust the below screenshot relationship between a table called PO Data and the Demand Seg, since I have to DirectQuery, I am forced in this configuration:

 

Any help is greatly appreciated.

    Hi TylerVono ,

    Please create a new calculated column:

     

    Stocking Agreement? = 
IF (
    ISBLANK (
        CALCULATE (
            COUNTROWS ( 'Demand Seg' ),
            'Demand Seg'[Item Number] = EARLIER ( 'Stocking Report'[Item Number] )
        )
    ),
    "No",
    "Yes"
)

     

    Output:

    Hello TylerVono ,

     

    The best practice is to build this model as a star schema model. then you'll have a dimension table for items that will be connected to both tables you have here and then you could easily work with both tables together viewed throught the dimension fields.

     

    check the star schema concept https://learn.microsoft.com/en-us/power-bi/guidance/star-schema
