How do you delete a reference to a dynamic document (referential integrity error)

Hi,

I need to delete a dynamic document referenced by another dynamic document. When I try to delete it I get a referential integrity error.

Is there a way to remove the reference to the document so that I can then delete it. I've checked the PTC knowledge base but the instructions are vague and seem to apply to Parts.

Any assistance would be grateful!

Thanks, Darquise.
