Roles in KM EP

Hello,

I have an ask regarding roles in SAP KM.

I want to set documents with specific criterias (moduls of SAP, project phases, document type, sector, ...).

In my company there are different roles: consultant, developer, manager... Every role wants an other view. (Manager -> project phases, Developer -> moduls of SAP ...)

Is it possible, that different roles can have different structures for the documents and that they can change between the views?

I would be very appreciate if somebody can help me.

With kind regards

Susanne
