Hello Ralf,
generally, you can use data from these fields in context factbase, which you can then reuse in IC context.
Typical use case is that you show alert and display some CAD data or have them as condition for alert (i.e. you can show IVR choice, selected language etc.).
Another use case is that you can pre-set Service Request multilevel categorization and many others.
Regards,
Dawood.
