Limitations when downloading a report .pbix file

• You can download a file while in either Reading view or Editing view. You must be at least a Contributor to the workspace that the report is in. If the report is based on a semantic model in another workspace, you need to be at least a Contributor to that workspace as well.
• If you create a report by using the Create button in the Power BI service, and it's based on a semantic model in another workspace, you can't download it.
• Reports created in Power BI Desktop must be published or uploaded to the Power BI service before you can download them.

• If you create a Power BI report based on a semantic model in one workspace and publish the report to a different workspace, you can download the report in live connected report mode only, if the semantic model is configured for large models or incremental refresh, or it has been modified by using the XMLA endpoint.
• Downloading a .pbix file after deployment isn't supported as part of the deployment pipeline (ALM).
• Downloading a .pbix file that's larger than 1 GB is only supported when the .pbix is in live connected report mode.
