Hi Miracle,

The model i'm trying to use is the Transfer Model - stock.picking 

Regarding your suggestion where can I add the "force_send=true" ? Could you explain a little more?

For further explanation, I want a scenario where when the person in inventory validates a receipt operation type for a warehouse, a notification should be sent to another user on the database.

If you were going to do something like this, how would you go about it?

Well, if you can throw more light to this, this depends on the model you are using. If possible you should explain further. but in your method you can add force_send=True. Regards
