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