WebNov 3, 2015 · You might recall from Chapter 2, “Introducing DAX,” that all the X-ending functions are iterators, that is, they iterate over a table and evaluate an expression for each row, finally aggregating the results using different algorithms. For example, look at the following DAX expression: [IncreasedSales] := SUMX ( Sales, Sales[SalesAmount] * 1.1 ) WebImplementing iterators. In DAX, iterators are functions that evaluate an expression for every row of a table and then aggregate the result. These functions are called iterators because the functions iterate over each row of a table. Within DAX, iterator functions end with an X character and include the following functions:
