QUESTION
I have this constraint:
...ANSWER
Answered 2017-Apr-21 at 03:57You have create new field nro_ctrl and you have write required=True in py file.
When you write required field in py file then it is required in Database table.
In copy method you are updating 'nro_ctrl': None. Due to that reason you are getting error in creating, because of none value is not allowing in required field.
If nro_ctrl field is required in invoice then you must give unique value in copy method of refund.
