Bind fields in AddressInformation in Customer

Hi all,

I need to insert the fields "Cidade" and "Estado", created in the AddressInformation node in the Customer XBO, to select in each address node the different values for these fields.

These fields was created in the Address node like below:

import AP.Common.GDT;

import AP.FO.BusinessPartner.Global;

[Extension] businessobject AP.FO.BusinessPartner.Global:Customer {

        // You must activate this business object before you can access the extension fields

        // or messages in script files, forms, and screens.

             node AddressInformation {

                    [Label("Estado")] element Estado:DEVESTADOCode;

                    [Label("Cidade")] element Cidade:DEVCIDADECode;

           }

             node Common {

           }

             node CurrentEmployeeResponsible {

           }  

}

And the modeldata stay like below:

I create a "Embedded Component", but I don't know how can I create the "InPort" field to bind then in the Screen.

Anyone can tell me how can I create parameters in ModelData in EmbeddedComponent ? and what is the Outport can I use to Bind parameters in the DataModel:

Thanks
