• What is the cause and solution for SAP error message USMD_GOV_API017 - Entity &1 with this key already exists in the object list ?

  The SAP error message USMD_GOV_API017 indicates that there is an attempt to create or update an entity in the object list, but an entity with the same key already exists. This error typically occurs in the context of SAP Master Data Governance (MDG) when working with data models and object lists.
  Cause:
  The error is caused by a duplicate entry in the object list for the entity you are trying to create or update. This can happen due to:
  
  An attempt to create a new record with a key that already exists in the database.
  A data import or replication process that is trying to insert a record that is already present.
  A programming error or misconfiguration in the data model or mapping.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check for Duplicates:
  
  Verify if the entity with the specified key already exists in the object list. You can do this by querying the database or using the relevant SAP transaction to view existing records.
  
  
  
  Modify the Key:
  
  If you are trying to create a new record, ensure that the key you are using is unique. Modify the key to avoid conflicts with existing records.
  
  
  
  Update Instead of Create:
  
  If the entity already exists and you intended to update it, ensure that you are using the correct update method instead of trying to create a new record.
  
  
  
  Data Import/Replication:
  
  If this error occurs during a data import or replication process, check the source data for duplicates and clean it up before attempting the import again.
  
  
  
  Review Custom Code:
  
  If you have custom code or enhancements in your MDG implementation, review them to ensure they are not inadvertently causing duplicate entries.
  
  
  
  Consult Documentation:
  
  Refer to SAP documentation or notes related to the specific version of MDG you are using for any known issues or additional troubleshooting steps.
