I was wondering if anyone knew of a way to prevent certain fields from updating with default/stored data when updating the Customer field on the Sales Order page under a certain condition.
My Goal: When on the Sales Order page, if a certain Order Type is selected (in this case, the order type that signifies it is a Sales Order created and sent from our website), changing the Customer Field does not update/overwrite the Financial Settings or the Shipping Settings. This is because the Financial and Shipping settings fields are populated and sent from the website, and may have more specific information than the stored Customer information.
I want to keep the loading of default data for other tabs/fields, but keep the customer-entered billing and shipping info.
