I need some help with hierarchy document templates.
I fear you may need some other product!
I created a document template and saved this to "my templates". Then I just opened a document based on this first template and saved this document as template to "my templates" to get the hierarchy.
Surely all you have here is two identical (unrelated) templates?
Next I changed the address in my first template and saved, after edit the second template I confirmed the update by my first template but nothing changed in my inherited template. What did I wrong?
I think all you did wrong is to imagine that templates derived from templates exist in a hierarchy. Unless I'm mistaken (always a possibility!) I think that templates exist only to create a particular starting point for a document. So the document created from your first template inherited its properties but no association with that (first) template. When you saved it as a template you had two identical templates with no association - so no hierarchy. You can change either of them independently but without any consequential changes.
I trust this helps.
