Course Group
Course groups serve to classify course types that share the same characteristics or deal with related subject matter such as Language Courses or Data Processing Courses.
A course group can contain subordinate course groups, such as English Courses or Microsoft Word Courses, which typically contain multiple course types. Thus, you can create a hierarchical structure of course groups.
The hierarchical structure, starting with course groups and working down, makes your course offering accessible and easy to navigate from the user's point of view, and easier to create from your point of view. The course groups occupy the highest level of this hierarchy.
You could decide to start with the course group Data Processing Courses, for instance. From here, you would work your way down to the individual course types and courses.
Course groups can also be selected as subject areas in the search for courses in the Learning Portal of the SAP Learning Solution.
Using course groups to structure your course offering improves system performance in the dynamic menus. To further improve performance, you can define a virtual business event group as the top node of your event hierarchy. You do so in Customizing for Training Management under Basic Settings ® Dialog Control ® Technical Settings ® Dynamic Menus in the entry SEMIN LROOT.
You create course groups in Customizing for Training Management under Course Preparation ® Training Provider ® Create Course Group or in the master data catalog. You can store the following information for course groups:
· Validity period of the course group

For clarity's sake, we recommend you to define 01/01 of the respective year as the validity start date.
· Long and short name
· Description of contents
The description you store here is used also for the course brochure if this course group is included in the brochure.
· Relationships to other course groups (belongs to) and to course types (incorporates).
· Indicator that the course group can be selected as a subject area in the search for courses in the Learning Portal of the SAP Learning Solution. See also Course Group Info (Infotype 1063).
The first two attributes are mandatory; all others are optional.
Course groups together with course types, courses, and the relationships that exist between them form a hierarchical structure. You generally maintain these relationships when you create a new object.
In the hierarchy, course groups occupy the top level. You can make the hierarchy as deep as you want by combining multiple course groups into one higher level group.

It is not mandatory to use course groups at all. If you decide not to use them, your course types are classified as unassigned course types and the resulting hierarchy is flatter.
In addition, any course types you create but do not assign to a course group are listed as unassigned course types.
Creating relationships between course groups and course types considerably improves system performance.
