Hello,
To a point - yes. First make certain you make a copy of the form in case of crossed hands and something goes amiss.
Using Form Navigator
, select the sub form to be the new main form. Drag it to the very top Forms
and release. It becomes a high level form. From there you can drag the old main form onto this new main form so it becomes a sub form.
Now the old main form still has two other forms which were sub forms and are now sub sub forms. You also need to drag these onto the new main form so you get your three sub forms back.
Now the forms are in order but you still need to verify and modify form/sub form properties. Of particular note would be master/slave links in all four. There may be other settings affected depending upon your design.
Edit:
Although using v6.3.4.2 not sure that is a problem. Here is my current test:
Start:
Make Oils
a main form - drag to Forms
:
Release button:
It is now a main form (primary if you will) and the process can continue from there.
