Copying Function Call Field to Other Entity

I have two entities with similar fields (covering address). One entity has function call field, which concatenates address fields into one string. Is there a way to copy/move this field to the other entity?

It is currently not possible to copy formula fields from one entity to another (because of the field references). But in case your scenario is to have similar entities with the same formula(s), then much better approach would be to:

  1. Define an inheritable virtual entity (Inheritable = True)
  2. Define all the common database fields there
  3. Define the formula fields there too
  4. Inherit from this entity in both target entities

This way you do not have to copy but instead you reuse the common data model.
