I want the Amount Due to show in a column in the Sales Order list.

Combined with the Payment Terms column, our warehouse can decide if the order is able to be dispatched (if credit terms are Immediate Payment, and there is an amount owing, they won't dispatch).

The field I want to display is Amount Due (amount_residual) and is found under Journal Entry (account.move). The type is Monetary. What are the steps to add a new column to reference this field?

Alternatively, Payment Status (payment_state) plus Due Date (invoice_due_date).
