Hi. I want to be able to lock payment terms in the sales order header so that the sales guys aren't able to change it when posting the invoice. We noticed that sometimes the sales are trying to give some more grace date to the customer regardless of what the actual terms are with the company. We want this field to be automatically populated from the customer data. We have locked the customer to be modified only by the finance. We want to do the same in the sales order header. Thanks in advance for the help!
