There are many different use cases to consider where shared datasets can be an advantage. Below I have quickly listed a few advantages, but probably you can think of many more.
– Centrally managed definitions and calculations to avoid different calculations for the same metrics and different versions of the truth.
– One central load from source to Power BI dataset, which lowers the performance impact on the source system.
– Easier to kickstart the data driven analytics experience for the business users and any other self-service analytics purposes.
Sharing here doesn’t mean giving to the broader world; it’s sharing within an organization.
