问题
I am trying to deploy a SSRS report to a 2016 server which uses a an API as it's data source. The URL for the API is generated dynamically via an expression which builds the query string based on a couple of report parameters.
In the past, using report manager I could set which account the API is called under.
Note that in the above screenshot the Connection string is still expression based.
However if I attempt the same thing in 2016 the connection string is wiped out.
Surely the connection string and the credentials should be independent, why has this changed in 2016 or is it a bug?
回答1:
I had a similar issue in ReportServer 2017; however if you click the button 'Revert to Default' (visible in the above screenshot) the Expression based connection string will magically reappear!
Nice feature - if you find it ;-)
