I'm using an Oracle 11g database as the datasource.
I'm getting timeouts in BIDS whenever I try to deploy a report with union statements. I can preview the report just fine. The query runs quickly in SQL Developer. It just times out whenever I try to actually deploy it. I'm also unable to deploy it on the SSRS web interface.
I've tried increasing HTTPExecution timeout in the web config files to no avail.
Anyone else seen this before?
