Power BI Report Publishing Problem: Duplicate Reports and Semantic Models
Hi Gandhia
,
It seems you’re facing challenges with maintaining lineage and ensuring consistent semantic models across your Power BI environments. Let’s dive into the issue and explore solutions:
- Understanding the Behavior: When you publish a report from Power BI Desktop to different environments (dev and prod), Power BI identifies datasets based on their connections. If there are even minor discrepancies, it treats them as separate entities. This behavior explains why you’re seeing new semantic models and reports instead of replacing existing ones.
- Potential Causes:
- Connection Differences: Even if the data source structure is identical, variations in server names, database names, or authentication methods can lead to separate models.
- Publishing Process: Ensure you’re publishing from the correct PBIX file and that dataset connections match between dev and prod.
- Resolution Steps: To address this issue and maintain consistent lineage:
- Standardize Connections: Verify that connection details (server names, credentials) are identical across environments. Adjust them manually in the Power BI Service if needed.
- Check Gateway Settings: If using an on-premises data gateway, ensure consistent configuration across environments.
- Re-publish Carefully: Republish the report, ensuring the PBIX file used for both dev and prod reflects the correct connections.
- Remove Unused Models: In the Power BI Service, delete any redundant semantic models to avoid confusion. Navigate to the Datasets section and remove duplicates.
- Consult Documentation: Microsoft’s documentation provides best practices for deploying Power BI reports. Review it for additional insights.
- Best Practices:
- Version Control: Use Git or other source control to manage changes and maintain consistency.
- Thorough Testing: Before deployment, rigorously test in dev to catch any discrepancies.
By following these steps and adhering to best practices, you’ll resolve the issue of duplicated semantic models and reports in your Power BI environments. 🚀

Thank you for your comprehensive response, I greatly appreciate it!! However, I didn't get help from that, at least not something concrete that would help me fix the problem. What differences can there be in the data source? How can I find out the details of the previous data source, such as authentication methods?
By the way, I noticed that Power BI has for some reason created a new semantic model, as it has assigned me as the owner of the semantic model (my colleague still owns the original semantic model). Does this help at all? What other additional information could I provide?
How can I proceed or how can I fix this issue?

Already a pretty old topic, but I ran into the very same issue today.
For me, this was caused by using folders.
In Power BI options and Settings, under Preview Features, ensure that you have the 'Enhance publish dialogs' and the 'Publish dialogs support folder selection' checkboxes checked. Then, on publish, make sure you publish to the same folder as the original report was in. Power BI will then detect that there is already a report with that name and will ask you if you want to overwrite that report.
