Here are some commonly used DAX (Data Analysis Expressions) functions in Power BI: 1. SUM() Purpose: Adds up all the values in a column. Syntax: SUM(column) Example: SUM(Sales[Revenue]) 2. AVERAGE() Purpose: Calculates the average of a column's values. Syntax: AVERAGE(column) Example: AVERAGE(Sales[Revenue]) 3. COUNT() Purpose: Counts the number of non-empty values in a column. Syntax: COUNT(column) Example: COUNT(Employees[EmployeeID]) 4. CALCULATE() Purpose: Evaluates an expression in a modified filter context. Syntax: CALCULATE(expression, [filter1], [filter2], ...) Example: CALCULATE(SUM(Sales[Revenue]), Sales[Region] = "North America") 5. IF() Purpose: Performs a logical test and returns different values depending on the outcome. Syntax: IF(condition, true_value, false_value) Example: IF(Sales[Revenue] > 5000, "High", "Low") 6. FILTER() Purpose: Returns a table that has been filtered according to certain conditions. Syntax: FILTER(table, condition) Example: FILTER(Sales, Sales[Revenue] > 10000) 7. RELATED() Purpose: Retrieves a related value from another table (useful for relationships between tables). Syntax: RELATED(column) Example: RELATED(Product[Category]) 8. ALL() Purpose: Removes all filters from a table or column. Syntax: ALL(table_or_column) Example: CALCULATE(SUM(Sales[Revenue]), ALL(Sales[Region])) 9. DISTINCT() Purpose: Returns distinct (unique) values from a column. Syntax: DISTINCT(column) Example: DISTINCT(Employees[Department]) 10. EARLIER() Purpose: Refers to an earlier row context in nested calculations. Syntax: EARLIER(column) Example: Often used in calculated columns to reference earlier rows in complex expressions. 11. LOOKUPVALUE() Purpose: Returns the value for a row where all specified conditions are met. Syntax: LOOKUPVALUE(result_column, search_column1, search_value1, [search_column2, search_value2], ...) Example: LOOKUPVALUE(Products[Price], Products[ID], Sales[ProductID]) 12. RANKX() Purpose: Returns the ranking of a value in a list. Syntax: RANKX(table, expression, [value], [order], [ties]) Example: RANKX(ALL(Sales), Sales[Revenue], DESC) #dataanalyst #datascience #talentelelearning #bhubaneswar #powerbi #CareerInData
