Step 2: Select Table visualization and drop Product and SalesAverage in the table created and we will have the following table displaying averages of each products sales. However, when you create a measure you must always specify a table where the measure definition will be stored. For example, you can specify a particular relationship to be used in a calculation. Lets create an example formula. For example, the following are all valid formulas. Information functions - These functions look at a table or column provided as an argument to another function and returns whether the value matches the expected type. After the opening parenthesis ( for the PREVIOUSQUARTER function, type Calendar[DateKey]. You specify the table that contains the column either implicitly, when you create a calculated column within a table, or explicitly, when you create a measure and specify the name of the table where the measure definition should be stored.
