DAX Filter Context

Hi,

 

I have a measure called _TotalUnits which works great. 

 

What I want to do is to work out the sum of DepreciationMonth from another table where the _TotalUnits > 0.

 

The difficulty is the filter/row context. I want this to work at the leaf level (lowest level rather than an aggregated level.

 

I was trying somthing like:

 

_Months = 
    VAR filterIndividualItem = 
            FILTER(FleetSize,[_TotalUnits]>0)
    RETURN
     CALCULATE(
                SUM(IndividualItem[DepreciationMonth])
                ,filterIndividualItem
     )

However, this isn't working.

 

Any ideas?

 

Thanks,

Bob

Yes, your formula is probably correct. Since I couldn't see your data I wasn't sure if there was another field that should be there. 

HASONEVALUE - To answer your question, I believe the the HASONEVALUE is the true/false condition that tells it when to use which behavior, so at the row level it will use the first part because it is at the row level and therefore 'has one value'. 

 

VALUES - For the Values function, this just creates a summary table with one column for the SUMX function to use.

So I don't know why this isn't working:

Could you share some sample data or what it is doing compared to the desired outcome?

Hi,

 

So here is some data:

Where there is a Total Hire > 0 then I want the _Test to be displayed.

 

My formula is:

_Test = CALCULATE(SUM(IndividualItem[DepreciationMonth]), FILTER(FleetSize,[_TotalUnits]>0))
 
_TotalUnits: CALCULATE(SUM(FleetSize[Unit]), FILTER(ALL(YearMonth[DateValue]),YearMonth[DateValue] <= MAX(YearMonth[DateValue])))
 
Any idea why it's not working or can you suggest an alternative?
 
Thanks

IF I use this formula: 

_Test = IF([_TotalUnits]>0,SUM(IndividualItem[DepreciationMonth]),BLANK())
 
THe row level looks correct but not the total

Try creating a second measure. 

_Test Total = 
IF(
    HASONEVALUE(
        IndividualItem[DepreciationMonth]),
        [_Test],
    SUMX(
        VALUES(IndividualItem[DepreciationMonth]),
        [_Test]
    )
)

That hasn't worked:

The total is still incorrect....

Hi,

 

So I think this works (replace the months with the Business Key):

 

_Test Total =
IF(
    HASONEVALUE(
        IndividualItem[ItemID]),
        [_Test],
    SUMX(
        VALUES(IndividualItem[ItemID]),
        [_Test]
    )
)

 

What is the purpose of the HASONEVALUE and also the VALUES functions?

 

Thanks
