Details
If you are having PMI dimensions with a PMI Balloons added, it is not possible to add associated objects to it afterwards
Solution
PMI annotations in a stack must have the same associated objects.
When you add PMI annotation to a stack, the annotation inherits the associated objects of the stack.
If the associated objects are unacceptable for the PMI annotation, the annotation is not allowed in the stack.
This inheritance of association is controlled by the Drafting preference, Inherit Associated Objects.
