Relationship Error

Problem: Error occurrs when trying to link multiple mobile business objects (MBOs) to a single child MBO.

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.

When a child mobile business object (MBO) has multiple parent MBOs, only one composite relationship is allowed.

Solution: Examine all of the relationships to a single child MBO and unselect Composite for all but one.

Note: Relationship errors can happen for a variety of reasons. For information about relationship validation rules and development guidelines, see:
