• 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.
  
  Cause:
  
  Duplicate Name: The most common cause is that the interface model name you are trying to use already exists in the system. Each interface model must have a unique name.
  Active Model: The existing model may be active or in use, which prevents you from creating another model with the same name.
  System Configuration: There may be system configurations or settings that enforce unique naming conventions for interface models.
  
  
  Solution:
  
  
  Check Existing Models: 
  
  Go to the relevant transaction (e.g., MDGIMG or MDG_MDL) and check the list of existing interface models to see if the name you want to use is already taken.
  If it is, consider using a different name
