About incremental changes and predecessors

A predecessor represents a sequential relationship between two processes, operations, or activities; the predecessor must complete before the second process, operation, or activity. You can use this relationship to track changes to the sequence of operations in a process or to activities in an operation. For example, you can use it to define a flow of operations or processes to be effective from a certain date or unit number. If you use a change object to add a predecessor, the change effectivity is attached to the predecessor and the predecessor becomes effective as of that change.

The following figure shows how Manufacturing Process Management displays the predecessors of a process or operation. If a + sign appears on the symbol, the predecessor was added with an incremental change; if a − sign appears on the symbol, the predecessor was removed with an incremental change.
