Hi, 

Your onchange method depends upon the operating_unit field. Since a default value is being loaded to the operating_unit, there is a change in value which will trigger the onchange method. So whenever the value in that field changes, even when the default value is loaded, it will trigger the onchange method.

may i have other way load default value first then my on change method run ? any logic

The onchange method will run if you are passing the default value. You can check whether the onchange is triggered for the first time and if yes, don't execute the remaining part.

how i know it's run first time ?

Mihran Thalhath

Try creating a new invisible field without any value. In your onchange check whether this field is empty or not. If it is empty, write some value to this field and exit. If it is not empty continue with your onchange. I mentioned this because this is easy to understand. There may be better ways to accomplish the same thing.

Cool! Please revert if you completed it!

When default method is launched, it changes the field value: false > default value. 

This operation is caught by @api.onchange. Hence, your onchange method is triggered.

There is now way to avoid this, rather than add some extra checks in your onchange. Perhaps, some check of a previous value (using self._origin).
