In a change source, you may identify that sub systems require modifications. 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: When using IFS Cloud ATCM to modify a configuration hierarchy, you must not use IFS Maintenix to modify it as well, as this will cause data corruption errors.
