Quote:2. If I go to add items to a Subform it allows me to do that. It does not require a key to a parent item. This allows creation of orphans.
If you are using natural linking, you are not creating orphans. No keys are needed. If you are using relational linking, you are responsible for your own bookkeeping. If you choose to match relational keys, fine. If you want to enter relational records on a form that do not necessarily appear under that parent, you can do that too.
Quote:3. If I go to a Parent form, it allows me to delete the form, creating orphans records in the sub form. Any way to create dependencies?
Same as above.
Quote:4. Adding Tabs to Subform, automatically creates new fields on ParentForm, no warning. May not be wanted.
I'm not sure what you mean by this. I'll give it a try and see if I see fields being added somewhere.
Quote:5. If multiple tabs on a form, pressing delete on one specific tab removes all tabs, not just the active one. Undo cannot undo. All work is lost.
Right-click on the tab group to add/remove individual tab pages. If you accidentally delete the tab group, exit the form without saving your changes. This will preserve your work since the last save. It is generally a good idea to save periodically as you work.
