• What is the cause and solution for SAP error message CACSDESIGNUI204 - The selected object already exists ?

  The SAP error message CACSDESIGNUI204: The selected object already exists typically occurs in the context of SAP Cloud Application Studio or SAP Business Application Studio when you are trying to create or define an object (like a business object, UI element, or other components) that already exists in the system.
  Cause:
  
  Duplicate Object Creation: You are attempting to create an object (e.g., a business object, UI component, etc.) that has the same name or identifier as an existing object in the system.
  Namespace Conflicts: If you are working in a shared environment or using a common namespace, there might be conflicts with objects created by other developers.
  Incorrect Object Reference: Sometimes, the error can occur if the system is referencing an object that was deleted or is in a different state.
  
  Solution:
  
  
  Check Existing Objects: Before creating a new object, check the existing objects in the system to ensure that the object you want to create does not already exist. You can do this by searching in the relevant repository or using the search functionality in the development environment.
  
  
  Rename the Object: If you find that the object already exists, consider renaming your new object to avoid the conflict.
  
  
  Use Unique Identifiers: When creating new objects, use unique identifiers or naming conventions to minimize the risk of duplication.
  
  
  Review Namespace: If you are working in a shared environment, ensure that you are using the correct namespace and that there are no conflicts with other developers' objects.
