BOM Relationships and BOMs

Only certain types of UML relationships are permitted when using case data. Whether or not a relationship is supported depends upon its type, direction, the source and target classes, and whether those classes are both in the same BOM and the same Business Data project.

Note: Bi-directional composition relationships, and unidirectional association or aggregation relationships, are not supported.

Validation errors are displayed if you try to define an invalid relationship between two classes.
