How to SUMX a column created with SUMMARIZECOLUMNS

I have the following DAX statement


,'Reporting Date'[YYYYMM]
,"New Column", <some logic>

and when I run this in an SSMS query, column [New Column] is returning the values I want. Now, in Power BI I have created this measure to return the sum of this new column:

Measure for New Column =
            ,'Reporting Date'[YYYYMM]
            ,"New Column", <some logic>
        ,[New Column]

But I receive this error:

Calculation error in measure: 'Measure for New Column': SummarizeColumns() and AddMissingItemsd() may not be used in this context.


Any ideas how I can, within a measure,  sum the columns created in a SUMMARIZECOLUMNS statement?

SUMMARIZECOLUMNS is only for queries, not for measures, since this function can't be used in context transition. Secondly, SUMMARIZE is for grouping only, not for any calculations (despite the documentation saying to the contrary). To simulate SUMMARIZE with calculations, you should use the hybrid: ADDCOLUMNS/SUMMARIZE. It's the only reliable way to do what you want. If you want to know why, you can read this:


You cannot use SUMMARIZECOLUMNS as the first parameter of a SUMX.  You should use SUMMARIZE instead.  Make sure the first parameter of SUMMARIZE is the fact table connected to your dimension tables.
