Default values in fields in SolMan Incident Management

Hi,

I am able to specify default values in the fields Component, Long Text and Short Text in the Create Message screen in the Settings for Current Configuration box in Servicedesk Workcenter (Incident Management). When trying to do the same with the Category field, there is no selection u201CSpecify Defaultu201D in the Settings for Current Configuration box. Why isnu2019t this possible? Do I have to do this via CRM and IMG?

Regards,

Kjell
