I am having an issue with VS2015 using SSDT to build new reports (SSRS 2016). When using a Shared Dataset and referencing that in the report, it does not work and gives a very vague error. I am connecting to a SQL 2008 R2 database for the dataset.
An error occurred during local report processing.
The definition of the report '/Dataset1' is invalid.
As soon as I change the dataset to be an embedded dataset, it works perfectly fine.
