Report Builder 3.0 - Dataset Credentials Do Not Work

Question

I am using SSRS 2008 R2 and Report Builder 3.0. I set up a shared data source via the browser (http://myserver/reports/) wherein the \"credentials are stored securely in the rep

Answer 1

After much gnashing and wailing seems like Report Builder uses information in definitions in Report Server to then run queries locally by itself, and not through Reporting Services.

My mistaken belief was that when I did something like Refresh Fields when setting up a Dataset, Report Builder was going through Report Services to get the relevant output and/or metadata. This seems to not be the case.

I had defined the connection string of the shared data source as Data Source=(local);Initial Catalog=. Now, this works when you are in Reporting Services' browser interface, but Report Builder seems to read the connection string and use it for itself. Reporting Services on my local development machine does not have any of the setup on the target server running these reports, so anything I would use will fail.

Changing the connection string to Data Source=;Initial Catalog=, instead of localhost, allowed Report Builder to work properly. (RB still popped up "Enter Data Source Credentials". I used my Windows credentials, which is a valid login on the target server.)
