Using parent and parenttype fields

Gd day,

Guys I was wondering if I can use parent field without problems from frappe?
I have a doctypes in transportation which are representing each part of the delivery process.

Doctypes:

  1. Delivery
  2. Delivery in the hub
  3. Delivery reached destination

Why split? Since I have to store around 200 fields (requires datetimes and other info), so I came up with the idea to keep them based on the state.

Delivery is a main doc, to the rest the user gets navigated. Is it possible instead of using links from each doc to use parent field?

Not a good idea to use parent and parenttype.

They are automatically identified as child tables. If that is not what you want, add new fields!
