Problem: A mobile business object (MBO) with multiple relationships to a single child MBO reports an error.
You see an error similar to this in Unwired WorkSpace:
Error: The target mobile business object 'MBO_name' can not be used in relationship 'relationship_name' since it already was used in a one-to-many or one-to-one relationship as a target.
A child mobile business object (MBO) with multiple relationships, supports only one cascade relationship.
Solution: Examine all of the relationships to a single child MBO and unselect Composite for all but one.
