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 global BOM and the same Business Data project.
Note: Bi-directional composition relationships, and uni-directional association or aggregation relationships, are not supported.
Validation errors are displayed if you try to define an invalid relationship between two classes.
