Searching for DAX formula - equivalent to Excel SUMIF

问题

I am searching for a DAX formula.

Specifically:

If SOLD (1st column) = count volume (second column), if not SOLD = 0 

I need to reflect the volume of SOLD in a new column. UNSOLD Volumes should be 0.

I attach the reduced data set.

If I understand, you want to only perform aggregation when the SOLD_UNSOLD column is equal to "SOLD", otherwise return 0? If so, the following formula will do this, you'll just need to update the column names accordingly. The outer IF prevents problems resulting from further evaluation (i.e. grand totals) and it's necessary to wrap the column in the VALUES function as this will turn the column into a table of the unique values of it.

'YourTable'[CountOfSold] =
    IF (
        COUNTROWS ( VALUES ( YourTable[SOLD_UNSOLD] ) ) = 1,
        IF (
            VALUES ( YourTable[SOLD_UNSOLD] ) = "SOLD",
            COUNT ( YourTable[ColumnToAggregate] ),
            0
        ),
        0
    )

The Excel SUMIF is closest to the DAX SUMX.

I'm not positive I'm understanding what you are asking for, but I think you'd want something like this:

SOLD_VOLUME = SUMX(Table1,
                   IF(Table1[SOLD_UNSOLD] = "SOLD",
                      Table1[DAILY_VOLUME],
                      0
                   )
              )

You could also do this with a filter:

SOLD_VOLUME = SUMX(
                  FILTER(
                      Table1,
                      Table1[SOLD_UNSOLD] = "SOLD"
                  ),
                  Table1[DAILY_VOLUME]
              )
