Hi db042190,
In Reporting Services, the shared data source is a set of data source connection properties, it does not contain query information used to retrieve data. Besides, it’s not supported to download the shared data source from report manager.
Reference:
Create, Modify, and Delete Shared Data Sources (SSRS)
If you have any question, please feel free to ask.
