is the method is action_update_quantity_on_hand ?
I try it but I had error
can you write the code to implement the method

feel free to update the question with the tried code and error you received

编写者

product = self.enve['product.product'].search([('id','=',product_id.id)])
product.qty_available = 100
product.action_update_quantity_on_hand ()
I have no change in this try and no error

as i suggested in answer, try simulating the same code execution of inventory adjustment with stock.quant model
