Managing incremental changes

Incremental change management is the process of controlling changes and providing an audit history of a part's definition and configuration. An incremental change collects together a number of structure changes to a component such as addition or removal of components or changes to attachments (data). Effectivity can be applied to incremental changes to configure the associated changes. This method of change control allows several independent structure changes to be made concurrently, including the addition or removal of unrelated components. Those changes can be implemented in any sequence.

The following actions constitute a reason for creating a change in manufacturing:

Adding and removing existing processes and operations from parent processes.
Replacing a process or operation with another process or operation.
Adding, removing, or replacing relationships between a top-level process and a target product, process, and plant with other product and plant objects.
Adding, removing, or replacing items from the setup structure at the operation level. This includes consumed items, work areas, and resources.
Adding, removing, or replacing objects that are attached to a process or an operation such as datasets, forms, and other items.
Adding, removing, or replacing objects in an activity folder with other objects such as other activities, tools, and programs.

A single change can add or remove multiple objects from an item or item revision. A single object can be added to an item or item revision with different effectivities by several changes and removed with different effectivities by several other change objects.

You can also create a baseline item revision by configuring all the incremental changes.

Note

Precedence relations between operations in a manufacturing process are not supported within Part Planner.
You can create incremental change (IC) information about occurrence groups and their content (children). However, configuring the view to show or hide configured changes does not work for this information. Only incremental change information that is common with the base view (in the item structure) is filtered.
