Purpose
To check the generated IDocs, the UPS must register itself for eachobject type with one event in the IDoc outbox and one event in the IDocinbox.
The event registry is generated here.

Integration
Registering the UPS with the events means that UPS-specificmodifications can be made to the IDocs. The IDocs allow themselves tobe checked by the UPS in the distribution process.

Prerequisites
The events are stored in the UPS Customizing settings inobject type maintenance.

Output
The system displays a list of the registrations.
