Count of metric based on match in 2 tables and no match in 3rd table

[Tob_P]

Above is a screenshot of a file available at https://drive.google.com/file/d/1mc5nLhZwJAIrlg_P1fL5XwkzAmQloGqh/view?usp=sharing

I have my Sales Header, Sales Line and Log tables and I'm looking to create a measure whereby I get a match between the CQ number in the Sales Header and Line tables but not in the Log table. So in the example above, the measure would return 2 as CQ000033 is not listed in the Log table.

Can someone help with how I can go about achieving this please?

Hi @Tob_P ,

First of all, many thanks to @AndyEagleton  for your very quick and effective replies.

Based on my testing, please try the following methods as workaround:

1.Create the simple table.

2.Create the new measure to get a match between three table.

Measure = 
VAR SalesHeaderCQ = DISTINCT('Sales Header'[No])
VAR SalesLineCQ = DISTINCT('Sales Line'[No])
VAR LogCQ = DISTINCT('Log'[No])
VAR IntersectCQ = INTERSECT(SalesHeaderCQ, SalesLineCQ)
VAR ResultCQ = INTERSECT(LogCQ, IntersectCQ)
RETURN COUNTROWS(ResultCQ)

3.Drag the measure into the card visual. The result is shown below.

Thank you both for your replies and suggestions - went with the variable option and it worked a treat!

Thanks again.

Somthing like this might work:

COUNTROWS( EXCEPT ( INTERSECT( VALUES(Header[CQ]), VALUES(Lines[CQ]) ), VALUES(Log[CQ]) ) )
