Measure to get previous value with same attributes

[gchn]

I have a table with multiple attribute/category columns (call them A1, A2, ...), a date column and a value column.

I've been trying for too long to get a measure that gives me the value for the previously available date, given that all attribute are the same.

Example:
date              A1  A2 .... value   new_measure
06/30/2023   a    c            1      BLANK

06/30/2023   b    d           2      BLANK

07/03/2023   a    c            3      1

07/04/2023   a    c           4      3

07/03/2023   a    d           5      BLANK

07/04/2023   a    d          6       5


How can I do it?

Nothing of the above worked. I ended up using an actually useful tool (a Python script) to do that before feeding it into Power BI. I guess it's my fault for thinking a Microsoft product would work.

HI @gchn,

Here is the dax measure formula and sample file about get the previous value based on use current date and multiple attribute field values:

formula =
VAR currDate =
    MAX ( 'Table'[date] )
VAR prevDate =
    CALCULATE (
        MAX ( 'Table'[date] ),
        FILTER ( ALLSELECTED ( 'Table' ), [date] < currDate ),
        VALUES ( 'Table'[A1] ),
        VALUES ( 'Table'[A2] )
    )
RETURN
    IF (
        prevDate <> BLANK (),
        CALCULATE (
            SUM ( 'Table'[value] ),
            FILTER ( ALLSELECTED ( 'Table' ), [date] = prevDate ),
            VALUES ( 'Table'[A1] ),
            VALUES ( 'Table'[A2] )
        )
    )

Hi @gchn 

Try using:-

new_measure =
VAR CurrentDate = MAX('YourTable'[date])
VAR PrevDate =
CALCULATE(
MAX('YourTable'[date]),
FILTER(
ALL('YourTable'),
'YourTable'[date] < CurrentDate &&
'YourTable'[A1] = EARLIER('YourTable'[A1]) &&
'YourTable'[A2] = EARLIER('YourTable'[A2]) &&
...
)
)
RETURN
IF(ISBLANK(PrevDate), BLANK(),
CALCULATE(
MAX('YourTable'[value]),
FILTER(
ALL('YourTable'),
'YourTable'[date] = PrevDate &&
'YourTable'[A1] = EARLIER('YourTable'[A1]) &&
'YourTable'[A2] = EARLIER('YourTable'[A2]) &&
...
)
)
)
Hope this will help.

Just the EARLIER function doesnt' work, can you be more specific?
