C4C - How to maintain object identifier mapping

[63abapdeveloper]

Hi,

we have many failed incoming messages in C4C. 

We get a number from sap mdg. If no number exists in the business partner, it will be entered. if there is already one number, it will not be overwritten.

Failure: Id Mapping for local object already exists. 

Service Interface ist BusinessPartnerReplicationIn. 

I find this in the documentation:

The web-service interface Maintain Object Identifier Mapping In enables you to connect external applications to your SAP On-Demand system and to maintain (create, update, or delete) object-identifier mappings between object identifiers in a remote business system, such as an SAP ERP or a SAP CRM suite system and object identifiers in the SAP On-Demand system.

How think here is only create and delete enabled. How can I change this. I want to enable update.

Thanks
