Dear Power BI heroes,
I have a question regarding the EARLIER function. I have the following DAX query:
Solved! Go to Solution.

An alternative version that uses EARLIER as you initially intended:
Unieke waarde V3 =
CALCULATE (
DISTINCTCOUNT ( 'AUDIT line'[Amnt] ),
FILTER (
ALL ( 'AUDIT line' ),
CALCULATE (COUNT ( 'AUDIT line'[Amnt] ), 'AUDIT line'[Amnt] = EARLIER('AUDIT line'[Amnt] ), ALL('AUDIT line')) = 1
)
)
or the same using variables instead of EARLIER, which is recommended nowadays:
Unieke waarde V3B =
CALCULATE (
DISTINCTCOUNT ( 'AUDIT line'[Amnt] ),
FILTER (
ALL ( 'AUDIT line' ),
VAR amnt_ = 'AUDIT line'[Amnt]
RETURN
CALCULATE (COUNT ( 'AUDIT line'[Amnt] ), 'AUDIT line'[Amnt] = amnt_ , ALL('AUDIT line')) = 1
)
)

@Anonymous
or yet another, more elegant, option:
Unieke waarde V4 =
COUNTROWS(
FILTER (
ALL ( 'AUDIT line'[Amnt] ),
CALCULATE (COUNT ( 'AUDIT line'[Amnt] )) = 1
)
)
Unieke waarde V5 =
SUMX (
ALL ( 'AUDIT line'[Amnt] ),
1*(CALCULATE (COUNT ( 'AUDIT line'[Amnt] )) = 1)
)

Hi @Anonymous
If this is a measure, there is no previous/earlier row context in your code that EARLIER can refer to and thus fails.
I assume you are trying to calculate the number of values in the 'AUDIT line'[Amnt] column that appear only once in the table. If so:
Unieke waarde V2 =
CALCULATE (
DISTINCTCOUNT ( 'AUDIT line'[Amnt] ),
FILTER (
ALL ( 'AUDIT line' ),
CALCULATE (COUNT ( 'AUDIT line'[Amnt] ), ALLEXCEPT ( 'AUDIT line', 'AUDIT line'[Amnt] )) = 1
)
)

@Anonymous There's no row context for EARLIER to operate on that provides that column. You could do this instead:
VAR __Amnt = MAX('AUDIT line'[Amnt])
VAR __Result =
CALCULATE(
DISTINCTCOUNT('AUDIT line'[Amnt]),
FILTER(
ALL('AUDIT line'),
'AUDIT line'[Amnt] = __Amnt
)
