Dashboard Mode - Why advanced DAX handles complex scenarios

Business Question

How can advanced DAX formulas help analyze sales data with complex conditions like filtering by product category and calculating running totals?

Sample Data

Date	Product	Category	Sales Amount
2024-01-01	Widget A	Gadgets	100
2024-01-02	Widget B	Gadgets	150
2024-01-03	Gizmo A	Widgets	200
2024-01-04	Gizmo B	Widgets	250
2024-01-05	Widget A	Gadgets	300
2024-01-06	Gizmo A	Widgets	350

Dashboard Components

• KPI Card: Total Sales
  Formula: Total Sales = SUM('Sales'[Sales Amount])
  Result: 1350
• KPI Card: Total Sales for Gadgets
  Formula: Total Sales Gadgets = CALCULATE(SUM('Sales'[Sales Amount]), 'Sales'[Category] = "Gadgets")
  Result: 550
• Measure: Running Total Sales
  Formula: Running Total = CALCULATE(SUM('Sales'[Sales Amount]), FILTER(ALL('Sales'[Date]), 'Sales'[Date] <= MAX('Sales'[Date])))
  Result example for 2024-01-04: 700
• Table Visual: Sales by Date and Category
  Shows Date, Category, and Sales Amount columns grouped by date and category.

Dashboard Layout

+----------------------+-------------------------+
| Total Sales (KPI)    | Total Sales Gadgets (KPI) |
+----------------------+-------------------------+
|                          Running Total Sales Chart          |
+-------------------------------------------------------------+
|                 Sales by Date and Category Table             |
+-------------------------------------------------------------+

Interactivity

A slicer for Category filters all components. Selecting "Gadgets" updates the KPIs and table to show only gadget sales. The running total recalculates based on the filtered dates and sales.

Self Check

If you add a filter to show only Category = Widgets, which components update and what happens?

• The Total Sales KPI updates to show 800.
• The Total Sales Gadgets KPI shows 0 because no gadgets are selected.
• The Running Total recalculates only for widget sales dates.
• The Sales by Date and Category table shows only widget rows.

Key Result

Dashboard showing total sales, category-filtered sales, running totals, and detailed sales by date and category using advanced DAX.
