Return values
A table which includes combinations of values from the supplied columns, based on the grouping specified. Only rows for which at least one of the supplied expressions return a non-blank value are included in the table returned. If all expressions evaluate to BLANK for a row, that row is not included in the table returned.
Remarks
SUMMARIZECOLUMNS does not support evaluation within a context transition. This makes it not useful in most of the measures – a measure with SUMMARIZECOLUMNS can be called also by CALCULATE but not in any case of context transition, including other SUMMARIZECOLUMNS statements. Client tools like Excel and Power BI almost always generate context transitions to evaluate measures in the reports.
