Rules based on multi-level categorization

Hi all,

I want to create a rule for service requests in the rule modeler based on multilevel-categorization. According to help.sap.com this should be possible.

But in the context SERVICEREQUEST there is no attribute for multi-level categorization and therefore I can't select it when creating my rule. I have assigned my categorization schema to the application area for the rule modeler. I have checked the other context areas as well, but I don't see anything that looks like multi-level categorization.

Does anyone have experience with this ? If the attribute should be created from scratch please guide me to how it should be configured.

Best regards

Annette
