Report not overwriting in workspace, creates a duplicate instead

[mp9531943781]

I'm running into a frustrating issue with a report that was originally published in our production workspace. I'm trying to update it by publishing the latest PBIX file, which I downloaded directly from that same workspace. But instead of overwriting the existing report, Power BI creates a duplicate with the same name.

The strange part is that when I publish the same file to my personal workspace, it works exactly as expected. It prompts me to overwrite the existing report and does so without any issues. But in the production workspace, it doesn't prompt at all and just creates a second copy.

The challenge is that I can't delete the original report or dataset before publishing, because both are being used as a source in other workspaces for other reports.

I've already tried using the latest versions of Power BI Desktop from May and June 2025, and I've published both from Desktop and the Service, but the behavior doesn't change.

Is there any way to fix this without deleting the original report and breaking downstream connections? Would appreciate any help or ideas.

Check for trailing spaces or other invisible characters in the pbix name.

You could run the Update Report Content In Group API to replace the context of the old report with the new one.

Or use git integration. Setup integration and sync the workspace to GitHub or ADO. Overwrite the contents of the old report with the new one. But don't overwrite the 
.platform file. Then push back to the workspace.
