Creating and Editing Comparison Group Types 
You can use the comparison group types delivered by SAP or create and edit your own group types.
On the Comparison Group tab page, choose a group type.
In the context menu, choose Create group type.
In the Details section, data for the new group type is displayed.
Choose Edit/Display Group Type, enter a name and a description, and choose an implementing class.
Note
The assigned implementing class defines the behavior of the group type. The following implementing classes are available:
Display
Completely independent comparison instances can be grouped together, for example, all SAP-CRM related comparison instances, independent of the business object.
Sequence
You can model the distribution of a business object from one system across many systems, for example, business partners from system A to system B to system C, and so on.
Prerequisites:
All comparison instances have the same mapping and key fields.
Source type and connection data of the target system in a comparison instance (for example, system A to system B) correspond to the data in the subsequent comparison instance (system B to system C).
Distribution
Using this group type, you can model the distribution of a business object from one system to many target systems, for example, business partners from system A to system B, system A to system C, system A to system D, and so on.
Prerequisites:
All comparison instances have the same source system and source type.
The mapping and key fields are identical.
