Concepts
All the contents managed in SAP KW are stored as info objects.
Using structures from a special kind of info objects, and hyperlinks, you can link info objects with each other.
Info objects with a common subject domain are collected and managed in folders.
Info objects and folders are each assigned to an area. The different areas in the SAP KW denote the purpose for which the contents are used. Generally, info objects within an area can be linked with each other using hyperlinks and structures, but info objects of different areas cannot be linked. There are exceptions, however: Info objects in the Training area can be linked to info objects in the Documentation area using hyperlinks, for example.
Info objects are stored in SAP KW in different versions, where different Contexts can be accessed. Customer-specific contents are normally created in enhancement contexts.
