When an assembly from the source is moved to target, you must also plan
all the components with the assembly. You can create intermediate
structures or remove existing subassemblies, but the hierarchical
integrity of the assembly should be maintained.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
