Daily DAX : Day 422 INFO.DATASOURCES

INFO.DATASOURCES DAX Function

Category: Information Function (Power BI specific)

Syntax

INFO.DATASOURCES ( )

Description

Returns a table containing metadata about all data sources used in the current Power BI model. This function is only available in Power BI (not in Excel Power Pivot or SSAS Tabular).

Returned Table Columns

Column Name Description
ConnectionString The full connection string used to connect to the data source
Url URL of the data sources (e.g., web, SharePoint, OData)
Server Server name for database connections
Database Database name (if applicable)
Type Type of data source (e.g., Sql, OData, Web, Folder, etc.)
PrivacyLevel Privacy level: None, Public, Organizational, Private

Common Use Cases

  • Auditing and documentation – Automatically list all data sources in a report
  • Dynamic data lineage reports – Build a report that shows where data comes from
  • Security & compliance – Identify reports using Private or Organizational data sources
  • Governance dashboards – Monitor which servers/databases are being used across reports

Example: Create a Data Sources Report Page

Add a new table visual and use this measure (or calculated table):

Current Data Sources = INFO.DATASOURCES()

This will display all data sources the current report connects to.

Important Notes

  • Only works in Power BI Desktop and Power BI Service
  • Requires the model to be in Import or DirectQuery mode
  • Does not return data sources used only in Power Query (M) if they are not part of the data model
  • Useful when combined with INFO.QUERIES() and INFO.MODEL() for full model documentation

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...
