• What is the cause and solution for SAP error message DDIC_ADT_DDLS017 - An object with the name &1 already exists in the namespace for entities ?

  The SAP error message DDIC_ADT_DDLS017 indicates that there is an attempt to create or modify an object (like a table, view, or other database object) in the Data Dictionary (DDIC) that already exists in the specified namespace. The message typically includes a placeholder &1 that will be replaced with the name of the object that is causing the conflict.
  Cause:
  The error occurs due to one of the following reasons:
  
  Duplicate Object Name: You are trying to create an object with a name that already exists in the same namespace. This can happen if you are trying to create a new table or view with a name that is already in use.
  Namespace Conflicts: If you are working in a custom namespace, ensure that the object name does not conflict with existing objects in that namespace.
  Transport Issues: Sometimes, objects may have been transported from another system, and the object already exists in the target system.
  
  Solution:
  To resolve the error, you can take the following steps:
  
  
  Check Existing Objects:
  
  Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to search for the object name that is causing the conflict.
  Verify if the object already exists in the system.
  
  
  
  Rename the Object:
  
  If the object already exists and you need to create a new one, consider renaming your new object to a unique name that does not conflict with existing objects.
  
  
  
  Delete or Modify Existing Object:
  
  If the existing object is no longer needed, you can delete it (if you have the necessary authorizations).
  Alternatively, you can modify the existing object if that is appropriate for your use case.
  
  
  
  Check Transport Requests:
  
  If the object was recently transported, ensure that the transport did not create duplicates. You may need to check the transport logs or consult with your Basis team.
  
  
  
  Namespace Considerations:
  
  Ensure that you are using the correct namespace for your custom objects. If you are working in a global namespace, make sure that your object names are unique across all namespaces.
