It's much more performant to only filter a single column. Now open Power BI SUMMARIZE function. SUMMARIZE (. This makes it not useful in most of the measures. This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. Remarks. How does the ISINSCOPE function (DAX) work?. A column cannot be specified more than once in the groupBy_columnName parameter. Example 11: Using Power Bi SUMMARIZECOLUMNS Function. One of the latest addition to DAX has been the ability to apply an external filter context to SUMMARIZECOLUMNS, which makes this function a perfect replacement for SUMMARIZE in DAX. It only specifies the set of columns to be subtotaled. sum of amount). The ROLLUP function is an add-on to the Summarizecolumns function.. Purpose of DAX ROLLUPADDISSUBTOTAL Function.
