Power BI Data Catalog

What is Power BI Data catalog?

Power BI Data Catalog is a central repository that stores information centrally and helps organize the metadata related to Power BI assets, such as reports, dashboards, and data sources. It allows users to explore different data sources through the data discovery process and helps them understand these sources. It is offered as a fully managed cloud service by Microsoft. It serves as a singular repository for all the users within an organization to contribute data knowledge, build communities of data repositories, and establish a data culture through a data governance structure.

Power BI Data Catalog is a crowdsourcing model that comprises annotations and metadata. Allows everyone, regardless of their role (i.e., developer, data analyst, or other consumers), to discover different data sources, understand their granularity, and consume them for their end reports or analysis.

Note: Power BI data catalog is not a built-in feature in Power BI. There are different external data catalog tools available that can easily integrate with Power BI to provide the features of the data catalog.

Key Takeaways

In the next section, we will see how you can create a Power BI catalog.

How to Create Power BI data catalog?

To create a data catalog, follow the instructions highlighted below:

  1. Select a data catalog tool such as Azure data catalog or Microsoft Purview service for integration into Power BI.

  2. Set up a connection between the data catalog and Power BI.

  3. Perform metadata scanning to scan through the Power BI assets such as reports, dashboards, data sources, and other datasets to collect the metadata definition. Ensure that before you run this scanning, your Power BI admin is set up. You can perform full scanning or incremental one.

  4. Review the collected metadata in the data catalog tool and enhance the details such as tagging, keywords, descriptions, or other details as needed.

  5. Establish the data governance rules, policies, and controls over data access. Set up data quality checks and usage monitoring for better control of the report output.

In this section, we will go through a couple of examples to understand how you can use the Power BI data catalog.

Example #1

In this example, we will see a data catalog use case in Power BI for data lineage for a financial organization. ABC Corp wants to implement data lineage to monitor data quality issues and understand the data consumption in downstream reporting to produce high-quality reports. To implement the above use cases, follow the steps outlined below:

Step 1: Use the Azure data catalog tool and connect to the Power BI reports or dashboards.

Step 2: Annotate your metadata, add tags with relevant keywords and accurate descriptions to your Power BI reports and dashboards

Step 3: Register your Power BI reports to make it discoverable and searchable.

Step 4: Set up a business glossary such as business definition, description of business rules, data stewardship, and data hierarchy, and tag your power BI reports with these business glossaries.

Step 5: Provide a user or group access to a data catalog and set permissions as per your requirements

Step 6: Run the metadata scanning to capture the data lineage and other definitions. It will make the Power BI reports and dashboards discoverable by other users.

Example #2

In this example, we will see a data catalog use case in Power BI for data governance compliance for a pharmaceutical organization. Bayer AG wants to comply with strict data governance rules and protection requirements by the regulators and monitor the data usage of different Power BI reports to avoid any sensitive information leakage. To implement the above use cases, follow the steps outlined below:

Step 1: Use the Microsoft Purview Service tool for data catalog and connect to the Power BI reports or dashboards.

Step 2: Register the data sources, classify the dataset, and tag them with the correct identifiers to locate any sensitive information

Step 3: Create a comprehensive data catalog mapping the data labels, business glossary, keywords, and data usage trackers across different users


The data catalog in Power BI provides multiple benefits, as highlighted below:

Easy data discoveryAllows users to quickly discover data sources, both internal and external, with search and filter mechanism ensuring quick navigation and reduction on the elapsed time on data searching and automated documentation.

Important Things to Note

  • As you use different data catalog tools, some of the features and offerings vary across the tools.
  • While metadata scanning helps you quickly data catalog all your metadata, it requires a set of Admin REST APIs in Power BI known as the scanner APIs to be set up and configured for integration into Power BI.
  • Some of the terms and concepts in the Data catalog may be challenging to understand and hence require extensive user training and continuous communication to ensure there is wide user adoption and data awareness.
  • Ensure that you regularly update the metadata and other data information of your Power BI assets to keep your data catalog up-to-date and usable.
  • Robust data governance policies and procedures are the need of the hour to streamline your data flow, achieve consistency, and eliminate unauthorized data access.
  • If you are using Azure data catalog, ensure that you migrate to Microsoft Purview services or other data catalog tools before August 2025 for uninterrupted experience due to non-IT support from Microsoft.
