The SWITCH function in Power BI is a versatile DAX function used to evaluate an expression against a list of values and return corresponding results.
1. Dynamic Segmentation or Categorization
Use SWITCH to create dynamic segments or categories based on specific conditions. For example, categorizing customers based on their sales amount:
Category = SWITCH(TRUE(), Sales[Total Sales] > 50000, "High Value", Sales[Total Sales] > 20000, "Medium Value", Sales[Total Sales] > 5000, "Low Value", "Very Low Value")
2. Replacing Nested IF Statements
SWITCH is more efficient and easier to read when replacing complex nested IF statements. For instance, replacing multiple conditional checks with cleaner syntax:
Rating = SWITCH(TRUE(), Sales[Total Sales] > 100000, "A", Sales[Total Sales] > 50000, "B", Sales[Total Sales] > 10000, "C", "D")
3. Custom Sorting or Ranking
You can use SWITCH to assign custom rankings or sorting orders for different categories in reports.
Custom Rank = SWITCH(Product[Category], "Electronics", 1, "Clothing", 2, "Groceries", 3, "Furniture", 4)
4. Conditional Formatting
Use SWITCH to create calculated columns or measures that assign color values or icons based on conditions, which can later be used for conditional formatting in reports.
ColorCode = SWITCH(TRUE(), Sales[Total Sales] > 100000, "Green", Sales[Total Sales] > 50000, "Yellow", "Red")
5. Dynamic Measure Selection
SWITCH can be used in a disconnected table with slicers to allow users to switch between different measures dynamically, enhancing report interactivity.
Selected Measure = SWITCH(SELECTEDVALUE(MeasureTable[Measure]), "Total Sales", [Total Sales], "Total Profit", [Total Profit], "Total Units", [Total Units])
