DAX Formula for Calculating 'Other' Element

Problem Statement

To calculate the 'Other' element using the formula: [ \text{Other} = \text{Closing Base} - (\text{Opening Base} + \text{Activation} - \text{Deactivation}) ]

You have a dataset containing records over three years.

DAX Formula

Here is the DAX formula to calculate the 'Other' element:

Other Element = 
SUMX(
    YourTable,
    YourTable[Closing Base] - 
    (YourTable[Opening Base] + 
     YourTable[Activation] - 
     YourTable[Deactivation])
)

Explanation

1. SUMX: This function evaluates the expression for each row in a table and then sums up the resulting values.
2. YourTable: Replace YourTable with the actual name of your table in your dataset.
3. Columns: Replace YourTable[Closing Base], YourTable[Opening Base], YourTable[Activation], and YourTable[Deactivation] with the actual column names in your dataset.

Practical Example

Assume you have a table named YearlyData with the following columns:

• ClosingBase
• OpeningBase
• Activation
• Deactivation

The DAX formula will look like this:

Other Element = 
SUMX(
    YearlyData,
    YearlyData[ClosingBase] - 
    (YearlyData[OpeningBase] + 
     YearlyData[Activation] - 
     YearlyData[Deactivation])
)

Sample Data

Consider the following sample data set:

Computation

The calculations for 'Other' element for each row would be:

• For 2021: ( 120 - (100 + 30 - 10) = \text{-10} )
• For 2022: ( 125 - (120 + 20 - 15) = \text{0} )
• For 2023: ( 140 - (125 + 25 - 10) = \text{0} )

Using the DAX formula, these individual 'Other' elements will be summed up.

Conclusion

By implementing the provided DAX formula, you can efficiently calculate the 'Other' element for your dataset over multiple years. This approach ensures precise computation and can be easily adapted to varying table structures within your data model.
