I switched over to using a shared Power BI dataset for my firms reports. This works great and is really nice to have a central place for all my DAX code, and for consistent measure formatting across reports.
Our BI reports are now in production and I want to create a test environment using a UAT sharted Power BI data model for my existing reports. Sirui Sun mentioned to someone asking about this limitation: "Hey Lee - yes, the capability above is on our backlog - it is a crucial piece of our ALM vision."
Until this feature is avilable, does anyone know a way of hacking the PBIX file to point to the UAT Power BI dataset manually?
No, you can't directly edit the .pbix hosted on Power BI Service. You can only download a .pbix copy from your workspace for UAT to on-premise machine. Then edit it and republish it onto UAT.
Sorry, I am not following. I have the .pbix file stored locally and do all my work in Power BI Desktop. I don't see any open to change the data source once the pbix file is first connected to a power bi service dataset.
