How to identify if a value exists in rows based on conditions in the same table

[danny_dmv]

Hello experts,

I got stuck with this project and can't seem to find a possible solution without creating another table. Basically, I have products in 12M that I need to see if they already exist in the previous years (<>12M). This is what I come up with. Obviously it is not working. Can anyone please take a look and point me to the right direction? Much appreciated!

Result = VAR pp = Table[Product] IN ALLSELECTED(FILTER(Table, Table[Time]<>"12M"), Table[Product]) RETURN

IF([Time] = "12M", IF(pp, "Existing", "New"), "")

Hi @danny_dmv ,

According to your description, here's my solution.

Create a calculated column.

Result =
IF (
    'Table'[Time] = "12M",
    IF (
        COUNTROWS (
            FILTER (
                'Table',
                'Table'[Product] = EARLIER ( 'Table'[Product] )
                    && 'Table'[Time] <> "12M"
            )
        ) > 0,
        "Existing",
        "New"
    )
)

Or if you prefer a measure.

Measure =
IF (
    MAX ( 'Table'[Time] ) = "12M",
    IF (
        COUNTROWS (
            FILTER (
                ALL ( 'Table' ),
                'Table'[Product] = MAX ( 'Table'[Product] )
                    && 'Table'[Time] <> "12M"
            )
        ) > 0,
        "Existing",
        "New"
    )
)

Get the correct result.

I attach my sample below for your reference.
