Hi @YukinobuUchida ,
From this article, you can see there is a limitation:
- This feature won't work with reports and the built-in downloadable samples originally created in the Power BI service, unless the report was created through the quick create experience.
- Reports created in the Power BI service must be saved before they can be downloaded.
- If your administrator has turned off the ability to download data, this feature won't be visible in the Power BI service.
- Datasets with incremental refresh can't be downloaded to a PBIX file.
- Datasets enabled for large models and the reports created from these datasets can't be downloaded to a PBIX file.
- Downloading a PBIX file after deployment isn't supported as part of the deployment pipeline (ALM).
- Usage metric reports can't be downloaded to a PBIX file.
- Datasets modified by using the XMLA endpoint can't be downloaded to a PBIX file.
- If you create a Power BI report based on a dataset in one workspace and publish to a different workspace, you and your users won't be able to download it. The download feature is not supported in this scenario.
- You can only download the original report. You can't download a copy of a report.
Based on the above posts, you can also refer to this similar thread:
