Using measure to check if even one value is true, then all of that value is true

[vhsn]

Category	Measure1
A	N
A	Y
A	N
A	N
B	N
B	N
B	N
C	N
C	N
C	N
C	Y
D	N
D	N

I'd like to use a measure to check: if even one category has Y, then all of that category is true, else false

For A = True, B = False, C = True, D = False

Thank you for the help

I would suggest something like this:

Instead of creating a measure to evaluate the first Y/N, create a conditional column (either on Power Query or as a calculated column) and call it "Yes/No?" Then:

Category Result =

VAR count_result = CALCULATE(COUNT('Table'[Yes/No?]), 'Table'[Yes/No?] = "Y")

RETURN

IF(count_result >= 1, "True", "False")

Then, create a table visual and add Category column and created measure.

The first measure is to exclude data that is in the currently selected slicer. I think I need that to be a measure to work properly? Unless.. is there a way to make the first measure also account for the category...?

Here is the extended sample:

Category	Month	Measure1
A	May	N
A	June	Y
A	July	N
A	August	N
B	January	N
B	March	N
B	April	N
C	February	N
C	March	N
C	May	N
C	June	Y
D	March	N
D	April	N

My current measure:

Exclude Month =

IF(

    MAX(table[Month]) IN ALLSELECTED(sample[Month]) && COUNTROWS(ALLSELECTED(sample[Month])) <> COUNTROWS(ALL(sample[Month])),

    "Y","N")

Let me suggest you a different approach then. Write a new measure called Exclude Month_Numerical : IF( MAX(table[Month]) IN ALLSELECTED(sample[Month]) && COUNTROWS(ALLSELECTED(sample[Month])) <> COUNTROWS(ALL(sample[Month])), 1,0)

Basically we are replacing Y/N with binary values that we can add.

Then, write a measure like this:

CategoryY/N = IF(SUMX('Table where "Exclude Month_Numerical" is hosted, [Exclude Month_Numerical]) >= 1, "True", "False")

This way we'll be adding up the results of the measures in each row, since we only deal with 0s and 1s works as if we were counting.

Let me know if it works.

That works! Thank you!
