Odoo 14 @api.onchange from a field of another class

Question

Hi, I just wanna now how I could make an @api.onchange, but from a field of another class, like:

I have in account.move the field "x"
And I have a method in account.move.line, [1]  that I want to use when the field "x" from account.move changes.

I tried @api.onchange(move.x) or @api.onchange( account.move.x) [2]  but it doesen't works : /

Thanks in advance

[1] https://account.move.line,
[2] https://account.move.x)

Hi,
try this:
@api.onchange(xx_id.x)
Note: xx_id is the  Many2one field.
2 Classes are related by the Many2one field and One2many field.
Hop it is useful.
