Hi again!
So, let me share what I think you can do here.
You have a custom attribute on quote and want to see the same attribute on order, right?
First solution:
- Create the attribute on quote entity and add it on form
- Create the same attribute on order entity and add it on form
- On mappings between the two entities, add the new one


What will happen is, when the order record was created from the quote record, the value of the attribute will be copied to the attribute on order. Do not forget to publish all customizations.

Order created from quote

The other solution is to add the custom attribute on the quick view form on quote entity.

And on the order form, add a new quick view form for the quote lookup



The result will be

No need to create the mapping on this solution
I hope that this information could answer your doubt.
Please let me know if you have any question.
