You may identify that sub systems require modifications and need to be added to a change source. Sub-systems are used to group configuration slots that make up a functional system of an assembly; they do not correspond to physical components.
To edit an existing sub system, assign a change source to the affected sub system, and in the Affected Sub Systems tab, edit information as required.
Note: You can add images to the subsystem with or without a change source. The image is directly applied on ATCM and is not published to Maintenix.
