Manually modifying the super_administrative_area__v, thoroughfare__v, and premise__v fields does not generate Data Change Requests (DCRs). Therefore, the user cannot apply the changes made to these fields.
These three fields are only used by the Loqate address cleansing tool. It is not possible to modify them via the User Interface (UI) by default.
In order to be able to modify these fields manually, an Enhancement Request needs to be opened. The Product Management team modifies these fields to be available for manual editing. In the request, it is required to specify in which countries the fields need to be made available.
