Basic Syntax for Analytical Expressions

Add Tables and Columns Reference

When creating analytical expressions, you add a reference to the tables and columns on which you want to perform the calculations. The basic format to add a column reference in an expression is to enclose the table name within single quotes, followed by the name of the column in square brackets. For example,

'FactOnlineSales'[SalesAmount]

Define Functions

Analytical expressions support a varied range of inbuilt functions. These functions can be used for performing complex calculations such as aggregation functions, date and time functions, filter functions, and so on. A function consists of a name and argument(s). The name of the function must be followed by a parenthesis in which the parameters are passed.

SUMX(ALL('FactOnlineSales'), 'FactOnlineSales'[SalesAmount])
