COUNT from other table

Hi pedroccamaraDBI ,

Per the description, I create some sample data and build the following relationships for them.

ContractSaller Table

Contract Table

Document Table

Then, create the following Measure.

CountDocument =

CALCULATE (

    DISTINCTCOUNT ( Document[DocumentID] ),

    TREATAS ( VALUES ( ContractSaller[ContractID] ), Document[ContractID] )

)

The result should look like this.

Also, attached the pbix file as reference.
