![]() Measures are used in reporting formats that support combining and filtering model data by using multiple attributes such as a Power BI report or Excel PivotTable or PivotChart. Measures are dynamic formulas where the results change depending on context. Calculated tablesĬalculated tables are computed objects, based on either a DAX query or expression, derived from all or part of other tables in the same model. Column values are only recalculated if the data is re-processed. The result for each row in the calculated column is calculated immediately and appears, for example, as 2010 Q1. For example, in a Date table, when the formula = & " Q" & is entered into the formula bar, a value for each row in the table is calculated by taking values from the Calendar Year column (in the same Date table), adding a space and the capital letter Q, and then adding the values from the Calendar Quarter column (in the same Date table). ![]() When a calculated column contains a valid DAX formula, values are calculated for each row as soon as the formula is entered. Calculated columns are not supported for models that retrieve data from a relational data source using DirectQuery mode.
