@borncorp thanks! It works when Incoterm fields have default values. But I wonder why

ignoreMandatoryFields: true

won't work on that field.

jake: If I recall correctly, that parameter only works if the field was only made mandatory but the initially it is not like department, location or custom field. But if the field is mandatory to begin with like Vendor in Purchase Orders, that parameter wont bypass those.

@rustyshackles so the only way would be to supply a value for that field right? I don't know why in our account TO's incoterm's field is null even though a value has been set in the Accounting Preferences.

Yes that is correct jake
