Dax Function: CLOSINGBALANCEMONTH
Category: Time Intelligence Functions
The CLOSINGBALANCEMONTH function in Power BI evaluates a given expression at the last date of the month in the current filter context. It is part of the Time Intelligence functions in DAX, designed to simplify calculations that depend on date-related contexts.
Purpose of the Function
The primary purpose of the CLOSINGBALANCEMONTH function is to determine the closing balance or value of a measure or expression for a specific month. It ensures that the result aligns with the last date of the month based on the data model’s date table.
Type of Calculations
- Aggregates or evaluates an expression at the last date of the month.
- Performs calculations using Time Intelligence for monthly closing balances.
- Supports measures like cumulative totals, balances, and inventory levels at month’s end.
Practical Use Cases
- Financial Reporting: Determine the month’s closing balance for accounts or transactions.
- Inventory Analysis: Track inventory levels at the end of each month.
- Cumulative Metrics: Calculate metrics such as total sales or outstanding balances at the month’s close.
CLOSINGBALANCEMONTH(<expression>, <dates>, [<filter>])
| Parameter | Type | Description |
|---|---|---|
expression | Scalar | The DAX expression or measure to evaluate (e.g., sales, balance, or inventory). |
dates | Column | A column containing date values. It must be part of a properly configured date table. |
[filter] | Optional | Additional filters to apply during the calculation. |
How Does CLOSINGBALANCEMONTH Dax Function Works?
- The function determines the last date of the month within the current filter context.
- It evaluates the provided expression using this date as a reference point.
- If a filter is applied, it narrows the context before determining the closing balance.
Mathematical Principle:
The function operates by leveraging the date hierarchy and calculates the expression based on the highest-level date available in the month.
What Does It Return?
The function returns a scalar value that represents the result of the expression evaluated on the last date of the month in the current context.
When Should We Use It?
- Use the
CLOSINGBALANCEMONTHfunction when you need to report values at the month’s end. - Ideal for periodic reporting, such as monthly financial summaries, inventory closing, or sales tracking.
Examples
Basic Usage
Closing Sales = CLOSINGBALANCEMONTH(SUM(Sales[Amount]), Dates[Date])
This formula calculates the total sales at the last date of each month.
Column Usage:
Closing Inventory = CLOSINGBALANCEMONTH(SUM(Inventory[Stock]), Dates[Date])
Tracks inventory levels at the month’s end.
Advanced Usage
Closing Profit = CLOSINGBALANCEMONTH([Net Profit], Dates[Date], FILTER(Region[Country], Region[Country] = "USA"))
Evaluates the closing profit for the USA by applying an additional filter.
Tips and Tricks
- Ensure that the
datescolumn belongs to a properly formatted date table for accurate results. - Combine with other Time Intelligence functions for more complex calculations.
- Use filters to refine the context and isolate specific segments of data.
Pitfalls:
- Misconfigured date tables can lead to incorrect results.
- Non-continuous or incomplete date ranges might result in errors.
Performance Impact of CLOSINGBALANCEMONTH DAX Function:
- Optimize the date table to ensure it has continuous and complete date ranges.
- Use indexed columns for better performance when applying filters on large datasets.
