DAX Calculations

The DAX tab within the Measure Calculations wizard can be used to create quick predefined DAX calculations.

To create custom DAX calculations, use the Custom Calculations wizard. This wizard is also used for managing, editing and deleting calculations.

Calculation Types

The following calculations are available.

Aggregate by Category

You will need to select a column which is the 'category' For example, selecting 'City' in a Max per Category calculation would return the highest measure value for all cities (apply all filters in the grid).

For a weighted average calculation, you also need to select the value which will act as the weight. This can be a measure or an aggregate of a column.

• Average per category
• Variance per category
• Max per category
• Min per category
• Weighted average per category

Filters

These calculations require a member from a column and calculates the measure value for that particular row.

• Filtered value
• Difference from filtered value
• Percentage difference from filtered value

Time Intelligence

For time related calculations a date column (as defined in the model) must be selected. Year-over-year etc. calculations also require a number which represents the number of years (or months etc.) over which to calculate the change.

• Year to date total
• Quarter to date total
• Month to date total
• Year-over-year change
• Quarter-over-quarter change
• Month-over-month change

Totals

• Total for subcategory (filters applied)
• Total for subcategory (filters not applied)
