We have an Oracle Retail Sales Audit 14.1 (ReSA) application which has some pre-built operational insights reports. These are OBIEE/Oracle BI Publisher reports for Sales Auditors or Financial managers.
While validating the ReSA application one of the user comes up with a question asking "When I try to view a report from the ReSA application it shows a blank BI Publisher report and if only I change the report format to PDF or html it shows up the report data.
After doing some R&D, I found the reason - it is because of the report level property "Auto Run" marked unchecked
Auto Run - This feature will not allow the report to execute immediately when user opens the report. This will prompt the user to select parameter values before it actually runs the report
