Optimize median measure in dax

I have the below median measure that I am using in my report, but when I publish to power bi service, I get this error message "Resources Exceeded This visual has exceeded the available resources. Try filtering to decrease the amount of data displayed". Resource Governing: This query uses more memory than the configured limit. The query — or calculations referenced by it — might be too memory-intensive to run. Either reach out to your Analysis Services server administrator to increase the per-query memory limit or optimize the query so it consumes less memory. More details: consumed memory 11753 MB, memory limit 10240 MB."

 

I have increase the capacity in both AAS and Power BI but still getting same error.

The measure is

CALCULATE ( MEDIANX( FILTER('rep vFact', 'rep vFact'[loanAmount] > 0), ( 'rep vFact'[loanAmount])) )

 

Please, how do I optimze this measure to be more efficient. Thanks

As a starting point you could try:

CALCULATE ( 
	MEDIAN( 'rep vFact'[loanAmount] )
	'rep vFact'[loanAmount] > 0
)

Also make sure the Loan Amount column is set to Decimal/Currency.

 

Not convinced above will work though. Will give it some more thought.

There is a limit on using MEDIAN on a table of 2 billion plus rows and suggested work around is the pattern in:
