## Using VALUES + ALL instead of just ALL. Resolution included - Need to know WHY it works

Hi there,

I recently ran into the following issue. My team has since resolved it (included) but we don't know 'why' it is the resolution.

The ask: Calculate a Distinct Count of Values where the Primary Key  IN  a list of PK's defined by a subquery.
The strange thing is, that when we ran the subquery through DAX Studio by itself, it returned the expected results.
Thank you for taking a look!

The DAX that WORKED:

VAR _subq =

CALCULATETABLE (
VALUES(  table[field] ),
ALLtable ),
table[field2] = "Yes"
)
VAR _count = CALCULATE (
DISTINCTCOUNTtable[field] ),
table[field] IN _subq)
RETURN
_count

The DAX that DID NOT WORK:

VAR _subq =

CALCULATETABLE (
ALL(  table[field] ),
table[field2] = "Yes"
)
VAR _count = CALCULATE (
DISTINCTCOUNTtable[field] ),
table[field] IN _subq)
RETURN
_count

Hi @prill22ta ,

Using a single column argument, ALL returns all the unique values of the column.

``````CALCULATETABLE (
ALL(  table[field] ),
table[field2] = "Yes"
)``````

So this statement returns the unique value of the table[filed] column, and the following table[filed2]="Yes" does not play a filtering role for the previous statement, because the ALL function ignores all filters

Both versions are a measure.

For the first dax code, is it a measure? what filter context does it have?
