Filtered table as filter argument (multiple columns predicate with AND condition)

A FILTER function filtering entire table using an AND condition on multiple columns is used as a filter argument in functions such as CALCULATE, CALCULATETABLE, etc.


Because the conditions are applied with an && operator, the multiple columns predicate can be transformed into one filter argument for each column, without filtering an entire table.

In order to keep the same semantics as the original filter, apply KEEPFILTERS over each filter argument.

Recommended articles:


Remove the Customer iterator and use KEEPFILTERS around each condition to maintain the same semantics, so the filter is applied only to the Customer[Country] and Customer[Age] columns instead of filtering the entire Customer table.

Original code

    [Sales Amount],
    FILTER ( 
        Customer[Country] = "Canada" 
            && Customer[Age] >= 21

Possible optimization

    [Sales Amount],
    KEEPFILTERS ( Customer[Country] = "Canada" ),
    KEEPFILTERS ( Customer[Age] >= 21 )
