In the Repair app, when you create a new Repair Order (RO), you can define a location (location_id). This location is where the product to be repaired is.

There is also a field to enter the invoicing method, where you can select none, before invoice or after invoice.

In the "Parts" tab of the new RO, when you add a part, you can define a "source location" and a "destination location" for each part.

What I want to achieve is to have the amount of the part sent to cost of sales when the invoicing method is "none".

So I created a new location that has the cost of sales set, called "Production no invoice". I need to automatically put that location in the Destination location for all parts in the "Parts" tab when the invoice method is none.

My problem is that the invoice method is in one view and the destination location is in the list view.

Any ideas?
