DAX - SUMMARIZE V SUMMARIZECOLUMNS in DAX filter

Hi

 

I have got some DAX where I join 2 tables in a union where some manual adjustments get added to data from a different source which makes up the majority of the data.

I need to filter out the main data so that if data (based on two fields) exists in the adjustments, I want to exclude those combinations appearing in the main data.

 

I have got the DAX working as I want it, but I was interested in finding out if I can replace the SUMMARIZE (below in RED) with SUMMARIZECOLUMNS.

It doesn't seem to work when I use SUMMARIZECOLUMNS, but I don't know why.

 

Many thanks

Oliver

 

 

zz Claims Return 2 =

SUMMARIZECOLUMNS (

    'Claims Solvency 2 Return'[Claim Reference],

    'Claims Solvency 2 Return'[UMR],

    'Claims Solvency 2 Return'[Risk Code],

    FILTER (

        'Claims Solvency 2 Return',

        NOT (

             ( 'Claims Solvency 2 Return'[UMR]  , 'Claims Solvency 2 Return'[Claim Reference] )

                IN SUMMARIZE  (

                    'S2 Manual (Claims)',

Hi @OliverO ,

According to your description, I created this data and copied your operation, and got the following error:

Claims Solvency 2 Return:

S2 Manual (Claims):

v-yangliu-msft_1-1616745942497.png

Use SUMMARIZE to get results:

This error occurs when using SUMMARIZECOLUMNS:

v-yangliu-msft_3-1616745942501.png

 

This is because you cannot apply an external filter context (such as CALCULATE or CALCULATETABLE) to SUMMARIZECOLUMNS, so you cannot use it in metric expressions, making it useless in most measures.
