I have successfully deployed our custom reports to our upgraded TEST environment and they run fine within our upgraded environment. I can access our new report server and can see all my custom reports. I downloaded Report Builder and can open my reports and see structure. But when I try to run the report from within Report Builder, I get an error connecting to the shared data source:
When you open a report in Report Builder… do you see more that one shared data source listed?
If so, I’ve fixed a few of my reports that were in this state…
Data Sources → Right Click → Data Source Properties
Then verify/fix one shared datasource, and delete the other one.
Ref screen shot…
Yes, may be… have you already tried to log on to the server as an admin and edit reports?
Also with the datasource…
What happens if you click the “Test Connection” button?
Or, if you click the “Browse” button - are you able to navigate to the displayed path and select it?
