Team absence report in RTC 3.0.1

Dear Support,

When I use the Team_Absences.rptdesign template (in order to have a global RTC report) from the following page

https://jazz.net/wiki/pub/Main/ReportsCentral/Team_Absences.rptdesign

and when I run the report, I get the following error message:

"Missing Required Parameter: Contributor".

Do you know why? Is it a problem of RTC version? Any other idea?

Thanks for your helpful help,

Regards,

Mikal Donini.
