How to Identify and Fix Missing Metadata in Power BI Data Products
You may see that Power BI sometimes shows metadata in one spot but not in your data product. Missing metadata can cause big problems. Users have a hard time finding the right data. They may stop trusting the data if details like descriptions or classifications are missing. Companies have seen bad data quality and weak rules when metadata is not complete. Good metadata helps you control who can see data. It keeps data safe and helps you follow the rules. Here is how Power BI stacks up against other platforms:
If you keep your metadata correct, it is easier to find data, keep it safe, and make better choices.
Key Takeaways

Connect Power BI with Microsoft Purview to scan metadata automatically. This helps you track data lineage and makes data governance better.
Identify Missing Metadata
Symptoms and Signs
You might see some signs when metadata is missing in Power BI. Sometimes, descriptions show up in Discovery view but not in Data Product view. Lineage information can be missing or not complete. This makes it hard to track where data comes from. If lineage is not complete, it takes longer to fix data problems. Not seeing all the details can make people confused. It can also make them trust reports less. If you cannot see everything, you might use old or wrong data.
Tip: Always look for missing descriptions, classifications, and lineage when you check your data products.
Tools for Detection
There are different tools to help you find missing metadata. Microsoft Purview lets you review and manage metadata in one place. Power BI Service helps you check dataset properties and refresh history. Catalog management in Purview shows metadata for assets and data products. These tools help you find missing fields or incomplete lineage before users have problems.
Manual and Automated Checks
You can use manual or automated checks to find missing metadata. Manual checks are good for development or quick reviews. You can open Power BI or Purview and look for missing fields. Manual checks help you learn about your data. They take time and might miss things in big environments.
Automated checks are better for regular and large checks. You can use scripts or APIs to scan for missing metadata on a schedule. Automation saves time and helps you find problems early. You need to set up permissions and keep tools updated. Many teams start with manual checks and switch to automation later.
Note: Common errors include credential problems, schema changes, and refresh timeouts. Use logs and alerts to find these problems fast.
Causes of Missing Metadata
Auto-Refresh Issues
Sometimes, metadata does not show up in Power BI. This can happen because auto-refresh does not work right. Microsoft Purview and Power BI need to refresh metadata often. If they do not, new descriptions or classifications will not appear. Microsoft knows this is a problem. You should refresh metadata by hand in Catalog management. Go to Data products and click Refresh on the asset details page. This will update metadata and let users see it.
Note: Errors like 'AppMetadataInaccessible' or 'TokenExpired' can stop metadata updates. Try clearing your browser cache. Sign out and sign in again. Check your dataset permissions if you see these errors.
Data Source and Credential Problems
Problems with data sources and credentials can cause missing metadata. Here are some common issues:
Credentials do not move when you import PBIX files with DirectQuery. The system removes private information. This causes missing metadata.
Gateway access fails if credentials are missing or wrong. Power BI cannot connect to your data source.
Firewalls can block Power BI service IP addresses from reaching your data source server, like Azure SQL. This causes access errors and missing metadata.
You need to update credentials using Power BI CLI with the right connection string format.
Giving firewall access to Azure IP addresses lets you update credentials and see metadata again.
Always check your credentials and network settings if metadata is missing.
Enhanced Metadata Format
Power BI uses a special metadata format called PBIR. This format saves report metadata as neat JSON files in folders. Each file keeps track of a part of your report, like pages, visuals, or bookmarks. The JSON schema at the top helps you check your metadata and use IntelliSense. This makes it easier to manage changes and work with others.
But there are some challenges. You cannot undo the upgrade to PBIR. Editing JSON files outside Power BI needs advanced skills. Wrong edits can cause errors when you open reports. Some features, like exporting to PPTX or PDF, subscriptions, mobile layouts, and Power BI Embedded, may not work yet. Microsoft plans to fix these problems in future updates.
Tip: Always check Microsoft’s known issues and community forums for the latest news on missing metadata and how to fix it.
Fixing Missing Metadata
When you see that metadata is missing in your Power BI data products, there are ways to fix it. You can use different steps to bring back and keep your metadata correct.
Manual Refresh in Catalog Management
A manual refresh in Microsoft Purview’s Catalog Management can help. This is useful if auto-refresh does not work or if new changes do not show up.
Step-by-step guide:
Go to Microsoft Purview and open Catalog Management.
Click the Data Products tab.
Look for the asset with missing metadata.
Click the asset to see its details.
Press the Refresh button to update the metadata.
Tip: Try a manual refresh if you see metadata in Discovery but not in your data product. Many people say this step brings back missing descriptions and classifications.
Remove and Re-Add Data Asset
If a manual refresh does not work, try removing the data asset and adding it again. This makes the system reload the metadata and can fix problems.
How to do it:
Take out the data asset from your data product in Catalog Management.
Wait a short time for the removal to finish.
Add the same data asset back to your data product.
Check if the metadata now shows up.
Many people find this method works well, especially when metadata will not update. It is a fast fix and does not need special skills.
Enable Enhanced Metadata
Turning on enhanced metadata in Power BI gives you more ways to control your dataset’s metadata. You can use outside tools like Tabular Editor to manage and get back metadata.
To enable and use enhanced metadata:
Make sure your Power BI workspace uses Fabric, Premium, or Premium Per User (PPU).
Get the XMLA endpoint connection string for your workspace.
Open Tabular Editor and connect to your Power BI model with the XMLA endpoint.
Turn off incremental refresh and automatic aggregations if they are on, because these can cause problems.
Make an empty PBIP file to hold your model metadata.
Find the
model.bimfile inside the.Datasetfolder of your PBIP file.Replace the
model.bimfile with the metadata you got from Tabular Editor.If you use TMDL format, match Tabular Editor’s settings to Power BI Desktop’s format. If not, use the
.bimformat.Open the changed PBIP file in Power BI Desktop. In Power Query, refresh each query by loading previews.
Save the file as PBIP or PBIX after you reload the model.
Enhanced metadata lets you make perspectives in Tabular Editor, organize tables, and choose what users see. Some features, like parameters, may not work with enhanced metadata, so check your dataset’s needs before turning it on.
Republish and Reload Metadata
Sometimes you need to republish your Power BI report or dataset to reload metadata. This helps when changes do not show up after refreshes or after you re-add assets.
Follow these steps:
Open your Power BI Desktop file.
Make any needed changes to metadata fields, like descriptions or classifications.
Save your changes.
Publish the updated report or dataset to Power BI Service.
In Purview or your catalog tool, refresh the metadata for the new asset.
If you get errors when publishing, like missing properties or file problems, do not edit PBIX files directly. Use tools like Tabular Editor or ask Microsoft support for help.
Troubleshooting API and Credential Errors
API or credential errors can stop metadata updates. Try these steps to fix common problems:
Update credentials in Power BI Service under dataset refresh settings. Click 'Edit credentials' and sign in again.
Refresh credentials if usernames or passwords have changed.
For OAuth problems, split queries for cloud and on-premises sources, then join them.
Check if your data source works and make sure Excel workbooks have data models.
Rebuild data combinations to match privacy levels if you see privacy errors.
Install 64-bit data providers on your gateway machine if needed.
Use anonymous authentication for Windows sign-in errors as a quick fix.
Use tools like Refresh history, Event logs, and Fiddler traces to look deeper.
Always check that your service principal has the right permissions when using APIs to get or update metadata. Replace placeholder values in API commands with real values to avoid sign-in problems.
