To access this dialog box from the model designer, in the formula bar above each table, click the function (fx) button. For more information about choosing functions to use in formulas, see DAX Introduction and Build a Formula.

The Insert Function dialog box is available only when you are building a formula. You can create calculations either in a calculated column, or in a PivotTable or PivotChart. Formulas that you build expressly for use in a PivotTable are also called measures. For more information, see Create a Calculated Column (SSAS Tabular) and Create and Manage Measures (SSAS Tabular).
