The group defines the data source location, the data source type, the collection identifier, and, optionally, the user ID and password for accessing the source data. When you add a registration group, PowerExchange also creates an extraction group and application group with the same name. You can also manually add an extraction group or application group.

PowerExchange stores registration group, extraction group, and application group information on the Windows system where the groups are added. The groups are unique for that system.

When you delete a registration group, extraction group, or application group, PowerExchange deletes local group information on the PowerExchange Navigator system. PowerExchange does not delete the capture registrations, extraction maps, or applications in the deleted group. Also, when you delete an application group or extraction group that PowerExchange generated, PowerExchange does not delete the registration group that generated the creation of this application group or extraction group.

If you add another group with the same properties as a group that you deleted, the new group contains any existing capture registrations, extraction maps, or applications for the deleted group.
