I'm in 220.127.116.11.210 and noticed when I run this report and hard code in the prompts, it doesn't generate the PDF and gives an error that it's blank.
When I actually go through the magnifying glass and choose the actual members from the list, then the PDF will generate.
Is this by design? I looked at the report definition and noticed the prompts are set up as query so I'm wondering if anything is a query, it needs to be selected from the magnifying glass?
that's a known issues with scripts and reports. You need to select it. Maybe fixed in 220.
* issues = issue :-)
