In the Kinetic Order Entry we have a Fax number field. I would like to replace this with a custom field from customer_ud and copy it to the OrderHed as it does the other customer fields when creating a sales order. I have renamed the text box in Application Studio, but what handles the copy from the actual customer to the OrderHed ?
Use a BPM for that.
Do a trace on Order entry and there should be a call something like ChangeCustomerID put a post processing BPM on that that populates the custom field with the data you’d like shown.
