Use item-item relationships to signify a dependency or connection between an item and other items. Items can be related to one another by system-defined or user-defined relationships. The system-defined relationships are determined by your process model and cannot be changed.
System-defined item-item relationships are:
Made Of. An item is made of those item revisions from which it was created by a build process.
Made Into. An item is made into those item revisions that are built from it.
Created From. An item is created from those earlier item revision(s) from which it made by merging or editing.
User-defined relationships can also be defined to identify relationships that are specific to your organization or product.
For two items to be related to each other:
The item types must be allowed to be in a valid relationship. This relationship is a parent-child one.
The child item must be open and the parent item must be held or open.
Example: A Common Item-Item Relationship
At Program Utilities Inc., executable programs, such as their flagship product Process Utility, are usually built from a number of object files, such as Setup, task1, task2, and Finish. The system-defined relationship Made Of is used to relate these types of items.
