Using EXCEPT with ALLEXCEPT and ALLSELECTED

[Farhan75]

Hi

I'm trying to use EXCEPT with ALLEXCEPT and ALLSELECTED to get the list of values in Column1 have been removed by a filter (i.e. the values not selected)

CONCATENATEX(

EXCEPT(

ALLEXCEPT('Table1,'Table1'[Column1]),

ALLSELECTED('Table1'[Column1])

)

,'Table1'[Column1],", "

)

Error = "Each table argument of 'EXCEPT' must have the same number of columns."

To get around this, I tried wrapping a SELECTCOLUMNS function around ALLEXCEPT, but I'm getting a different error

CONCATENATEX(

EXCEPT(

SELECTCOLUMNS(ALLEXCEPT('Table1,'Table1'[Column1]),"Column1",'Table1'[Column1]),

ALLSELECTED('Table1'[Column1])

)

,'Table1'[Column1],", "

)

Error = "A single value for column "Column1" in table 'Table1' cannot be determined"

Hoping somebody can help me out with this please???

Hi, 

I am doing something similar to this, the difference is that I am trying to calculate an average(frmo a different table) for all of the values not selected. This sis the calculation I am using

Trend Chart Other =

IF (

ISBLANK ( [Avg Result] ),

BLANK (),

CALCULATE (

[Avg Result],

EXCEPT (

ALL ( SurveyQuestionQ11[value], SurveyQuestionQ11[ResponseId] ),

ALLSELECTED ( SurveyQuestionQ11[value],SurveyQuestionQ11[ResponseId])

)

)

)

Avg Result is a measure from another table but has a relationship to SurveyQuestionQ11. 

The math is not calcualting correctly and I cannot figure out why.

Try this one

Measure =
CONCATENATEX (
    EXCEPT ( ALL ( Table1[Column1] ), ALLSELECTED ( Table1[Column1] ) ),
    Table1[Column1],
    ", "
)

Your measure could also work if you make these modifications

1) In ALLEXCEPT's arguments put all columns other than column1 (in red font below)
2) Instead of Table1[Column1] use only [Column1] because SelectColumns removes data lineage (in red font below)

Measure = CONCATENATEX(
EXCEPT(
SELECTCOLUMNS(ALLEXCEPT(Table1,Table1[OtherColumn2],Table1[OtherColumn3]),"Column1",Table1[Column1]),
ALLSELECTED(Table1[Column1])
),Table[Column1],", ")

Hi @Zubair_Muhammad

Thanks for your reply.

The reason I am using ALLEXCEPT with Column1 is because I only want to display the values excluded by direct filtering on this column, not by cross filtering on other columns. 

I'd already tried your first example, but unfortuantely, this also gives me values excluded by cross filtering. So does your second. Please see example PBIX below.

Many thanks for your help so far

Kind regards

Hi @Farhan75,

Sorry for the delay.

Based on your sample pbix, I found that the problem is caused by the slicer of column1 will be filered by the slicers of column 2 and column 3. 

By my tests, I have no better dax ecpression to display the value which will not be filtered by column 1, column2 and column3 at the same time.

As a workaround, you could try this measure below and turn off the interaction between the column 2 and column 3 for that measure.

MyMeasure = --show values DIRECTLY unselected excluding those removed by cross filtering
IF(
    ISFILTERED('Table1'[Column1]), -- checks if filtered
        CONCATENATEX(
            EXCEPT(
                ALL(Table1[Column1]),
                ALLSELECTED(Table1[Column1])
            )
            ,[Column1],", "
        )
    ,"All"
)

Here is your desired output.

Here is the attachment you could refer to.

If I get the better solution, I will update here.
