I have some reports built in SSRS 2008. These reports are not showing any data. Data source for these reports has correct credentials and connecting successfully.
As a background, We had an application with same reports and this copy is running fine.
We created a copy of these reports accessible under different folder and with a different data source. Everything is same except Data source pointing to a different database with same structure.
How can we debug this and figure out why data is not being fetched by this new copy of reports.
