• What is the cause and solution for SAP error message MDG_OIF203 - Interface model name &1 is already in use; use a different name ?

  The SAP error message MDG_OIF203 indicates that the interface model name you are trying to create or modify is already in use. This typically occurs in the context of SAP Master Data Governance (MDG) when you are working with interface models for data replication or integration.
