Below is the formula to arrive at the total price in the single-step itself. New Column = RELATED(TimeZone[Value]) This function is not supported for use in DirectQuery mode when used in calculated columns or row-level security (RLS) rules. Instead of adding two extra columns, we can arrive at the total value in the single-column itself. The syntax for FILTER() requires that the first parameter be a table, not a column. Defining measures within a DAX query. Another way to create ad hoc calculations is to define them first using the DEFINE MEASURE command.

This can be helpful when you want to count the number of unique values in a column, or use a list of unique values for other operations. This blog post provides everything you need to know about the DAX RELATED and RELATEDTABLE functions for Power BI advanced calculations and reporting. Excel and Analysis Services require you to write the expression in the formula textbox when you select the last column on the right – “Add Column”.
