How to apply filter on multiple columns with OR operator using DAX formula

Hi Anonymous 

You can tweak your current syntax to apply Filter Condition 1 OR Filter Condition 2:

EVALUATE
FILTER (
    SUMMARIZECOLUMNS (
        Asset[Type],
        Asset[Program],
        Asset[Category],
        Sales[Period],
        Sales[Quantity]
    ),
    OR (
        Asset[Program] = "Primary Assets",
        Asset[Category] IN { "ASM", "NSN", "TPG", "STB" }
    )
)

One potential performance issue with FILTER( SUMMARIZECOLUMNS(...)) is that SUMMARIZECOLUMNS returns the full table (which contains some unwanted rows) which is then iterated over with FILTER.

An alternative, which may perform better, is to construct a table containing the filter condition, and provide that as an argument in SUMMARIZECOLUMNS after the Groupby columns. Something like this:

EVALUATE
VAR FilterTable =
    UNION (
        CROSSJOIN (
            TREATAS ( { "Primary Assets" }, Asset[Program] ),
            ALL ( Asset[Category] )
        ),
        CROSSJOIN (
            ALL ( Asset[Program] ),
            TREATAS ( { "ASM", "NSN", "TPG", "STB" }, Asset[Category] )
        )
    )
RETURN
    SUMMARIZECOLUMNS (
        Asset[Type],
        Asset[Program],
        Asset[Category],
        Sales[Period],
        Sales[Quantity],
        FilterTable
    )
