for the integration of SAP Sales Cloud and SAP Marketing Cloud via CPI, the OData Service CUAN_BUSINESS_PARTNER_IMP_SRV is used by default.
When I create a Custom Field in SAP Marketing Cloud I have only the option to enable it for the OData-API CUAN_BUSINESS_PARTNER_IMPORT_SRV.
In the Communication Scenario SAP_COM_0017 that is used for the integration both services are listed:
When I try to call the services (e.g. via Postman) with the user that is maintained for the Inbound Communication, it works fine for the CUAN_BUSINESS_PARTNER_IMPORT_SRV.
For the CUAN_BUSINESS_PARTNER_IMP_SRV I always get a 403 - Forbidden Error. So I'm not able to see if my custom field is also enabled for that service.
1. Does anybody have an explanation for that behavior? How can I access that service?
2. How to enable a Custom Field for the OData-Service that is used for the integration? Or do we have to change the service in CPI if we would like to use custom fields?
