SDK: Create C4C BusinessPartner from C4C Customer

Hi All,

We replicate customers from ERP to C4C via HCI. The replication is working fine. I.e. Accounts in C4C gets their own internal ID and External ID from ERP.

what we want is that when a customer is replicated from ERP,   "ID mapping for Integration" of BusinessPartner is updated with the same External ID as the ERP Customer Number.

Below scenario is works fine.

i.e. ERP: Customer 0001  =====>  C4C : Account Int ID : 1111

                                                                   Account Ext.Id: 0001

                                                                   ID Mapping for Integration ERP Accounts :  ID 1111 = Ext.ID 0001

Requirement is that

i.e. ERP: Customer 0001  =====>  C4C : Account Int ID : 1111

                                                                   Account Ext.Id: 0001

                                                                   ID Mapping for Integration ERP Accounts :  ID 1111 = Ext.ID 0001

                                                                   ID mapping for Integration BusinessPartners: ID 1111 = Ext.ID 0001

I tried extending the BO ObjectIdentifierMapping, however could not access BusinessPartner attributes. I could very well access BO Customer properties.

what should be right approach in achieving this requirement.
