Hi Victor thanks for the feedback and I agree with you.
Butweneed to fill the dependent dropdown of field "Cidade" based in the value of field "Estado". I made it through the Context Mapping, because it is not possible to carry out this procedure direct in the standard screen.
So, is possible apply the fill dinamically like your explanation in the post Create a dependent dropdown with context mapping but apply in the AddressInformation in the XBO of Customer ?
Remembering that these fields should be changed and writeable for each address that the customer has.
