How To Add Index In Power Bi

Adding an index in Power BI can be achieved using calculated columns or measures. Let’s look at both methods with examples:

Method 1: Using Calculated Columns

Calculated columns in Power BI are formula-based columns that are computed during the data loading process. To add an index using calculated columns:

1. Load your data into Power BI.
2. Select the table you want to add an index to.
3. Click on the “Modeling” tab in the Power BI ribbon.
4. Click on “New Column” under the “Calculations” group.
5. Enter a name for your index column, e.g., “Index”.
6. In the formula bar, enter the formula for the index. For example, if you want a simple sequential index, you can use the formula “RowNumber = RowNumber()”.
7. Press Enter to create the calculated column.

Here’s an example:

        Index = RowNumber()
    

Method 2: Using Measures

Measures in Power BI are calculations based on the aggregated data. To add an index using measures:

1. Load your data into Power BI.
2. Select the table you want to add an index to.
3. Click on the “Modeling” tab in the Power BI ribbon.
4. Click on “New Measure” under the “Calculations” group.
5. Enter a name for your index measure, e.g., “Index”.
6. In the formula bar, enter the formula for the index. For example, if you want a simple sequential index, you can use the formula “Index = COUNTROWS(‘Table’)”.
7. Press Enter to create the measure.

Here’s an example:

        Index = COUNTROWS('Table')
