On the “Custom fields” tab, you can configure the output of custom fields in several blocks: “Find or create a customer”, “Billing details”.
Replace fields with customer order fields. This parameter allows you to save the values of custom fields in the user profile. When creating a new order, the values of custom fields will be loaded from the user ‘s profile.
For example, I specified the custom field “Gender”.
When creating an order, I selected the client and specified the value of the “Gender” – Female field and clicked the “Create order” button.
Now, go to the user profile. The value of custom field was saved.
Now I will create a new order and specify the user “Mary Bint”. The value of the custom field was loaded from the user profile to the new order.
