I have gone through the DBI implementation guide and tried to create a new report.
Created a report and published it.
In the process of creating Initial Request set (in Daily Business Intelligence Administrator), could not find the report (that I have developed in Daily Business Intelligence Designer) in Generate Request set window.
To enable dashboards and reports:
1. Using the Daily Business Intelligence Administrator responsibility, navigate to
Setup : Global > Administer Content.
2. Query the dashboard or report that you want to implement.
3. Enable the Implement check box next to the dashboard or report. You can enable
several dashboards and reports at the same time.
