One report or dataset for multiple apps

Hi,

I am facing a similar issue in a deployment I am working on. I think this can be eased by doing the following.

1) Separate the model from the report pages. let's call this model.pbix

2) Use the onedrive\sharepoint file management to publish reports to the app content workspace

3) Create a report1.pbix and use the Power BI Service as the datasource (pointing to the model in 1)

4) you can then automate the copying of report1.pbix from content workspace a to content workspace b using onedrive & flow 

I think a solution like this would work .. would need to try it out and see if content workspace's can access each others dataset on the service and make sure there are no permission type issues. 

You may have already solved your issue, anyhow hope these thoughts may help.
