• What is the cause and solution for SAP error message CNV_DMC_SIN517 - Plant Data: &1 already exists ?

  The SAP error message CNV_DMC_SIN517 indicates that there is an attempt to create or import plant data for a plant that already exists in the system. This error typically arises during data migration or conversion processes, particularly when using the SAP Data Migration Cockpit or similar tools.
  Cause:
  The error occurs because:
  
  The plant code you are trying to create or import is already present in the SAP system.
  There may be duplicate entries in the source data that you are trying to migrate.
  The migration process is attempting to create a new plant with an identifier that conflicts with an existing one.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Plants:
  
  Verify if the plant code you are trying to import already exists in the SAP system. You can do this by navigating to the relevant transaction (e.g., OX10 for plant maintenance) and checking the list of existing plants.
  
  
  
  Review Source Data:
  
  Inspect the source data you are trying to migrate. Look for duplicate entries or incorrect plant codes that may be causing the conflict.
  
  
  
  Modify Migration Data:
  
  If duplicates are found in the source data, you may need to remove or modify these entries to ensure that each plant code is unique before attempting the migration again.
  
  
  
  Use Update Instead of Create:
  
  If the plant already exists and you need to update its data, ensure that your migration process is set to update existing records rather than create new ones.
  
  
  
  Consult Documentation:
  
  Review the documentation for the specific migration tool you are using (e.g., SAP S/4HANA Migration Cockpit) for any specific guidelines or configurations related to plant data migration.
  
  
  
  Error Logs:
