SAP Marketing Cloud
Reproducing the Issue
For example you are trying to retrieve the additional IDs of the ID Origin SAP_CRM_BUPA.

Result: any data is fetched.
Cause
There are two possible reasons:
1. The Origin ID SAP_CRM_BUPA does not have any related Additional ID.
2. The ID SAP_CRM_BUPA was imported as Additional ID and not Origin ID.
Resolution
The Get operation of the API_MKT_CONTACT_SRV returns results based on Origin IDs.
You need to import the ID SAP_ERP_BUPA as Origin ID, not Additional ID.
