Convert value from measure to a Constant Value

Hi,

 

Not sure why this happens.  

I have a variable measure that gives me the expected value, but doesn't perform as expected when plugged into the main measure.

When I hardcode the same variable value, the main measure performs as expected.

I've been reading around the powerbi community and what I need from the variable is to convert the value to a constant.  Is this possible?

 

Here is the full Measure:

//This variable needs to be converted to a constant value.

VAR Variable1 = CALCULATE( sumx(maintable, maintable[Value]), Filter(All(maintable[position]), maintable[position] = 1), maintable[intensity]=0 )

 

 

RETURN

//The VAR from above is plugged into the measure below.  When Variable1 is instead hardcoded with the same fixed/contant //value the measure works perfectly.  Is there a workaround?

//In other words, remove the context from the calculated variable values so it's seen as a constant singular value.

if(or(SUM(maintable[position]) = 0 && sum(maintable[Value]) = Variable1,

(SUM(maintable[intensity]) = 0 && sum(maintable[Value]]) = Variable1)),

Sum(maintable[Value]) +1, Sum(maintable[Value]))

 

Thank You.

    selimovd looking at the measure, it will not work because you are using only one column in ALL function and it will fail to filter Intensity column. Just my 2 cents.

    Hi  roncruiser ,

     

    Modify your variable as below:

     

    Variable1 =
SUMX (
    FILTER (
        ALL (maintable[position],maintable[intensity]),
        maintable[position] = 1
            && maintable[intensity] = 0
    ),
    maintable[Value]
)

     

     

    Best Regards,
    Kelly

      Hey parry2k ,

       

      you're absolutely right. I Didn't test the function. I found the approach with CALCULATE and SUMX unusual, so I tried a quick fix. But you're right, like this it won't return a table.

       

      Best regards

    Hey roncruiser ,

     

    in Power BI there is nothing like a fixed value for a measure. 

    A measure always has a filter context and is executed in that context. If you measure returns another value than when you integrate it into another value, then the context is different.

     

    Can you show the main measure and how you integrate it? Also, please show some data and how you analyze (table, bar chart, etc.). That makes it easier to understand what contexts are working on a measure.

     

    If you need any help please let me know.

      Hi  roncruiser ,

       

      Modify your variable as below:

       

      Variable1 =
SUMX (
    FILTER (
        ALL (maintable[position],maintable[intensity]),
        maintable[position] = 1
            && maintable[intensity] = 0
    ),
    maintable[Value]
)

       

       

      Best Regards,
      Kelly

      Hey roncruiser ,

       

      in general it's very uncommon to use SUMX within CALCULATE and also that you put some arguments in FILTER and some in the context of CALCULATE.

       

      I would do the FILTER part in the SUMX:

      Variable1 =
SUMX(
    FILTER(
        ALL( maintable[position] ),
        maintable[position] = 1 && maintable[intensity] = 0
    ),
    maintable[Value]
)

       

      Can you check if that will result in the same value?

       

      Then when you add the "Variable1" in your main measure, which of the results will be executed?

       

      If you need any help please let me know.
