Hi,

What about setting an exception(User Error) while deleting the record

You can add that exception by super the function def unlink(self)

Regards

def unlink(self) will be called once the record is saved but it will not work if the line is not saved.

Ex:

Vendor invoice line which is filled by onchange of PO.

If I open a vendor invoice line before saving the invoice form and it wont call a unlink function if I click remove button.

Is there any feature available like delete="false"

I tried but I don't see Remove in the popup of o2m field.
