Matrix totaling of a measure

[judddonnelly]

I have the following measure that has some strange sub and grand total results:

Xcap = if(Capability[xNetOil] > (Capability[xCapability] * 0.8), (Capability[xNetOil]), if(Capability[xCapability] > 0 , Capability[xCapability], Capability[NetFcstOil]))

xCapability =

VAR Cap24 =

VAR __startDate = CALCULATE( MIN(Capability[CALENDAR_DATE] ), DATEADD( Capability[CALENDAR_DATE], -45, DAY ) )

VAR __endDate = CALCULATE( MAX(Capability[CALENDAR_DATE]), DATEADD( Capability[CALENDAR_DATE], -1, DAY ) )

RETURN

CALCULATE(SUM( Capability[Net Oil] ), DATESBETWEEN( Capability[CALENDAR_DATE], __startDate, __endDate ), Capability[Hours On] = 24 ) / CALCULATE(COUNT( Capability[CALENDAR_DATE] ), DATESBETWEEN( Capability[CALENDAR_DATE], __startDate, __endDate ), Capability[Hours On] = 24 ) *.98

return

sumx(values(Capability),cap24)

xNetOil = (sum(Capability[Net Oil]) )*.98

All other data elements are columns from the dataset.

This looks like a measure totals problem. Very common. See my post about it here: https://community.powerbi.com/t5/DAX-Commands-and-Tips/Dealing-with-Measure-Totals/td-p/63376

This worked but not sure why.

xCap Total =

IF (

HASONEVALUE ( 'Capability'[well_name] ),

[Xcap],

SUMX ( ALLSELECTED ( 'Capability'[well_name] ), [Xcap] )

)
