Definition
The connection provides the technical link between the utility grid and the installations.
The connection processing function is optional. You will require it if you wish to manage the technical data for the connections (for example, length of the line).
Use
The connection is modeled as a piece of equipment with the equipment category A: Connection from the Plant Maintenance (PM) application component.

You can change the equipment category A in Customizing for Plant Maintenance and Service Management by choosing Master Data in Plant Maintenance and Service Management ®
Maintenance and service (such as initial creation of a connection, or malfunction repair) are managed using the functions of the Customer Service (CS-SO) component. In the Sales and Distribution (SD) application component, quotations are created and services are billed.
The connection is allocated to the connection object when the device is installed, or when the location of the equipment is changed in the functional location.
