I have a publisher 11g (v 18.104.22.168) report with a single parameter. The report is based on a data model not a subject area. I created a dashboard put a dashboard prompt and link to the report in separate section on the same page. The dashboard prompt sets a presentation variable named the same as the parameter in the report.
The problem was when I created the dashboard prompt, it forced me to select a subject area which I did (though did not want to) and then I created both a column and variable prompts. But clicking on the
report link completely ignored the value that I thought would be passed in the presentation variable to the report.
Side note : My report uses a pdf template for its layout where I have mapped the columns names from my data model to the form fields on the pdf form. I noticed that if I create a publisher report based on a subject area, then I do not have the choice to choose a PDF as a template type for my layout. (I only see BI Publisher Template as a choice).
I see some documentation online that suggest it could be done in 10g.
