I'm currently using a local instance of SSRS 2016. I've noticed that when I deploy a project and access the reports via Report Manager those with shared data sets will not render, instead I am met with an error message as below.
"An error has occurred during report processing. (rsProcessingAborted) The permissions granted to user 'Sam\Samuel' are insufficient for performing this operation. (rsAccessDenied)"
I'm sure the problem has something to do with shared data sets as reports in the same project will open fine so long as the data set they're using is embedded and thus not shared.
Any advice as to why this is might be happening would be hugely appreciated.
