Daily DAX : Day 436 ENDOFMONTH

Power BI DAX Function: ENDOFMONTH

Description

The ENDOFMONTH function is a time intelligence function in DAX (Data Analysis Expressions) used in Power BI. It returns a table containing a single column and single row with the last date of the month in the current filter context, based on the provided dates.

Syntax

ENDOFMONTH()

Parameters:

  • : A column reference containing dates, or a table expression returning a single column of dates.

Return Value: A single-column table with one row containing the end-of-month date.

Example

Assuming you have a Date table marked as a date table:

Month End Sales = CALCULATE(
    SUM(Sales[Amount]),
    ENDOFMONTH('Date'[Date])
)

This measure calculates the total sales as of the last day of the month in the current context (e.g., for monthly reports, it aggregates sales up to month-end).

Use Cases

  • Month-end reporting: Calculate metrics like closing balances, inventory levels, or total sales at the end of each month.
  • Time intelligence calculations: Often used inside CALCULATE to modify filters for period-end snapshots (e.g., account balances that are only meaningful at month-end).
  • Comparing period-end values: Useful for year-over-year or month-over-month comparisons of end-of-period figures.
  • Semi-additive measures: Ideal for measures that should not be summed across days, but evaluated only at period ends.

Note: ENDOFMONTH is preferred over EOMONTH(..., 0) in time intelligence scenarios because it returns a table filter suitable for CALCULATE. It requires a proper date table for accurate results across contexts.

Daily DAX : Day 131 SELECTEDMEASURE

 The SELECTEDMEASURE function in Power BI's DAX (Data Analysis Expressions) language is a powerful tool used primarily within calculation groups to dynamically reference the measure currently being evaluated in a report. It’s part of the calculation group feature introduced to streamline complex reporting scenarios and improve maintainability by reducing the need to duplicate measure logic. What is SELECTEDMEASURE? SELECTEDMEASURE is a DAX function that returns a reference to the measure that is currently active or "selected" in the context of a calculation group. It doesn’t take any arguments and is typically used in the expression of a calculation item within a calculation group. This allows you to write generic logic that can dynamically apply to whichever measure is being evaluated in a visual, without hardcoding specific measure names. Syntax SELECTEDMEASURE()     Returns: A reference to the measure currently being evaluated in the report context. Use Case SELECTEDME...

Daily DAX : Day 446 INFO.CSDLMETADATA

Power BI DAX Function: INFO.CSDLMETADATA INFO.CSDLMETADATA` is a specialized DAX function introduced as part of a broader set of "INFO" functions (like `INFO.TABLES` or `INFO.MEASURES`) used for **model introspection**. It allows you to programmatically access the underlying structure of your Power BI semantic model. What does it do? The function returns a table with a single column containing the Conceptual Schema Definition Language (CSDL)  metadata of your model in XML format . In plain English, it exports a highly technical "blueprint" of your entire data model—including tables, columns, relationships, and measures—as a structured XML string. It is essentially the DAX equivalent of the `DISCOVER_CSDL_METADATA` Dynamic Management View (DMV) used in Analysis Services. --- Syntax and Output The syntax is straightforward as it requires no arguments: ```dax EVALUATE INFO.CSDLMETADATA() ``` Return Value : A table with one column and one row. Content : A long string ...

Daily DAX : Day 453 ENDOFWEEK

Power BI DAX Function: ENDOFWEEK Description The ENDOFWEEK function is a Time Intelligence function in DAX (Data Analysis Expressions) used in Power BI. It returns the date that represents the end of the week containing a specified date (typically Saturday, as weeks are considered to start on Sunday by default in DAX time intelligence). Syntax ENDOFWEEK( [, ]) : A column reference (usually from a Date table) or a date expression. Required. : Optional. Specifies the week-ending convention. Default is Saturday if omitted. Examples 1. Basic usage (default: week ends on Saturday): End of Week = ENDOFWEEK('Date'[Date]) For a date like January 8, 2026 (Thursday), this would return January 10, 2026 (Saturday). 2. In a measure for cumulative sales up to end of week: Total Sales to End of Week = CALCULATE( SUM(Sales[Amount]), DATESBETWEEN('Date'[Date], ST...
