Step-by-Step Approach: Mastering Tableau Window Sum

Conquer tableau window sum with this straightforward guide:

1. Create a Calculated Field: Navigate to Analysis > Create Calculated Field.
2. Name Your Field: Assign a descriptive name that reflects the calculation's purpose.
3. Utilize the WINDOW_SUM Function: Within the formula field, type WINDOW_SUM(SUM([Your Measure Name])). Replace [Your Measure Name] with the actual measure you want to calculate the sum for.
4. Define the Window (Optional): Specify the timeframe for the running total using FIRST() and LAST() functions. For instance, WINDOW_SUM(SUM([Sales]), FIRST() - 3, LAST()) calculates the sum of sales for the current row and the preceding three rows.
5. Drag the Field to Your Visualization: Once created, drag the calculated field containing the tableau window sum to the desired area of your visualization (e.g., Rows, Columns, Marks).
