Overview of KM Services (SAP Library - Knowledge Management Security Guide)

Overview of KM Services

The Knowledge Management capabilities of the portal use numerous services. SAP distinguishes between global services and repository services. The former are used system-wide; the latter can only be used in the repositories that they have been activated in.

For more information, see Structure link Global Services and Repository Services.

Many services have other services as prerequisites, because they provide certain basic functions. The dependencies are listed in the tables below. If a service uses a service user, this is entered in the Comments column.

Global Services

Note

Since global services can be used system-wide and also by other usage type in their own scenarios, you must not deactivate them.

The following table lists the global services and displays the dependencies to other services.

Repository Services

In principle, all repository services are optional. You can activate them for each repository that you want to use the service in. If you do not want to use a service, you deactivate it in the configuration of the repository manager in question.

In the portal, choose System Administration ® System Configuration ® Knowledge Management ® Content Management ® Repository Managers to do this. Open the configuration of the repository manager in question and deactivate the service affected.

Note

When creating a repository manager, choose only those repository services that you really intend to implement (see Minimal Configuration).

The following table lists the repository services and displays the dependencies to other services.
