Hi dgwilson 

 

This happens because "Prep Data for AI" in Copilot requires tenant-level enablement + specific permissions, even if you have Copilot access in PBI Desktop.

 

Here are the 3 things to check:

1. Tenant Admin Setting
Fabric Admin Portal > Tenant settings > Copilot > "Users can use Copilot and other AI features" must be ON
Also enable: "Prep Data for AI" / "Copilot in Power BI" for your org

 

2. Report Ownership / Permissions
"Prep Data for AI" only works if you are the Owner or have "Reshare + Build" permission on the semantic model.
Since you said "not the original author", ask the owner to give you Build permission on the dataset.

 

3. License
You need Fabric Free / Pro / Premium Per User + Copilot for Fabric license assigned to you.

The error "You don't have access to Copilot" in that pane specifically means point 2. Desktop Copilot works but Model-level AI doesn't.

 

Try: Open the semantic model > Manage permissions > Add yourself with Build. Then reopen report.

Hope this helps!

    Take a look at my follow up message - where I said I tried this in the office and it worked.

    Thus the fault is a networking error of some description - though the error message doesn't provide any clues.

    Now, while I'm not the original author (they have left the business)... I have published this to a test workspace. Completed refreshes etc. So I'm the effective owner. I'm workspace Admin as well.

    Plus tenant admin - settings have not been reconfigured. And it's proof that all is OK in the office.
