Card percentage of total sum - 2 different tables

[Anonymous]

Hi - I have 2 tables... Table A and Table B.

I want to find the percentage of the grand total from a field in Table A let's call it "Class". Class has 3 options "1, 2, or 3".

Table B has the actual dollar amounts let's call it "sum total value" that relate to table based on a common field.

I know about the calculate function, but I'm not sure how to do this formula since the data is coming from 2 tables.

I have the following so far:

Measure 1 =

DIVIDE (

SUM ( Table A  [Sum Total Value] ),

CALCULATE ( SUM ( TABLE A[Sum Total Value] ), ALLSELECTED ( TABLE B [CLASS] = '1') )

)

Hi @Anonymous ,

“I want to find the percentage of the grand total from a field in Table A let's call it "Class". Class has 3 options "1, 2, or 3".”

“Table B has the actual dollar amounts let's call it "sum total value" that relate to table based on a common field.”

I’m not sure what’s your data model.

Which column do the two tables use to connect with each other?

Is the [Sum total value] column a DAX column?

Is it like this?

I had created such a measure and add it into a card:

Percentage1 = 
DIVIDE(
    SUMX(
        FILTER(
            TableB,
            TableB[Class] = 1
        ),
        RELATED(TableA[Sum total value])
    ),
    SUM(TableA[Sum total value])
)

Or you can do like this:

Measure = 
IF(
    ISFILTERED(TableB[Class]),
    DIVIDE(
    SUM(TableA[Sum total value]),
    SUMX(
        ALLEXCEPT(
            TableB,
            TableB[Class]
        ),
        RELATED(TableA[Sum total value])
    )
    ),
    BLANK()
)

If they’re not what you want, please give me a sample data model, and tell me what visualization do you ultimately want to achieve.

If it is sloved, could you kindly accept it as a solution to close this case?

If not, please let me know.
