This page describes the limitations of the Stages BIRT Designer compared to the Standard BIRT Designer.
Drill Down
Drill Down functionality from BIRT through separate reports is not supported by Stages.
Notice: The root cause is that the Report design files (*.rptdesign) are stored in the process database and there is no URL to address them.
Report Parameter Formats
Report Parameter formats are not supported.
Report Libraries
Report Libraries are not supported.
Hyperlinks in Data Elements
Hyperlinks on data elements are not supported.
Note: A hyperlink can also be generated by a dynamic text element. The content-type must be set to HTL and a real href HTML element must be formatted.
