Dax Outer Join

Hello

 

I’m building a PBI report to look at SSRS report usage. I need a measure that returns the usage of reports created in the last six months. Two tables used in the measure

 

Catalog table --> Contains report details, attributes like  ReportID, name, createdDate etc.

ExecutionLogStorage table --> Contains report usage details, attributes like ReportID, UserId, TimeStart etc. 

 

Measure currently  is …

EVALUATE
ROW (
    "b",
        CALCULATE (
            COUNTROWS ( ExecutionLogStorage ),
            'Catalog'[CreationDate]
                >= DATE ( YEAR ( NOW () ), MONTH ( NOW () ) - 6, DAY ( NOW () ) )
        )
)

 

This only returns reports that have had usage. I need it to return all reports in the last 6 months, even if the usage is 0, I guess I need the DAX equivalent of a left outer join.

 

Any suggestion much appreciated.

Thaks in advance.

Roy

Thanks for the quick reply. 

 

I added the +0 to the measure, but it returns all reports and seems to be overwriting the filter ???

@ryand009 Maybe: 

EVALUATE
ROW (
    "b",
        CALCULATE (
            COUNTROWS ( ExecutionLogStorage ),
            'Catalog'[CreationDate]
                >= DATE ( YEAR ( NOW () ), MONTH ( NOW () ) - 6, DAY ( NOW () ) )
        ) + 0
)
