Paginated report dataset from Power BI DAX query

Hello,

 

Is there anyone who created a datset in Paginated report using Power BI Dax query (from Performance Analyzer)?

 

Query:

// DAX Query

DEFINE

  VAR __DS0Core =

    SELECTCOLUMNS(

      KEEPFILTERS(

        FILTER(

          KEEPFILTERS(

            SUMMARIZECOLUMNS(

              'DimLocation'[Country],

              'Action'[Control],

              "CountRowsFactAction", CALCULATE(COUNTROWS('Action'))

            )

          ),

          OR(

            NOT(ISBLANK('DimLocation'[Country])),

            NOT(ISBLANK('Action'[Control]))

          )

        )

      ),

      "'DimLocation'[Country]", 'DimLocation'[Country],

      "'FactAction'[Control]", 'Action'[Control]

    )

 

  VAR __DS0PrimaryWindowed =

    TOPN(501, __DS0Core, 'DimLocation'[Country], 1, 'Action'[Control], 1)

 

EVALUATE

  __DS0PrimaryWindowed

 

ORDER BY

  'DimLocation'[Country], 'Action'[Control]

 

My question: How can I create a parameter if I use this query? How to write a DAX code included in this query to create a parameter in paginated report?

    Use the @ symbol for a parameter and make sure it's mapped in the parameters section.

     

    Here's a simplified example based on your query:

    DEFINE
    VAR CountryFilter = TREATAS ( { @Country }, 'DimLocation'[Country] )
EVALUATE
SUMMARIZECOLUMNS (
    'DimLocation'[Country],
    'Action'[Control],
    CountryFilter,
    "CountRowsFactAction", CALCULATE ( COUNTROWS ( 'Action' ) )
)
