• What is the cause and solution for SAP error message UJ0_EXCEPTION126 - Object name &1 already exists ?

  The SAP error message UJ0_EXCEPTION126, which states "Object name &1 already exists," typically occurs in the context of SAP BusinessObjects or SAP BW (Business Warehouse) when you are trying to create or rename an object (like a query, report, or data source) with a name that is already in use.
  Cause:
  
  Duplicate Object Name: The most common cause of this error is that you are attempting to create a new object or rename an existing object to a name that is already assigned to another object in the same context (e.g., same folder, same data source).
  Namespace Conflicts: If you are working in a multi-user environment, another user may have created an object with the same name after you checked for existing names.
  System Caching: Sometimes, the system may not reflect the most current state of the objects due to caching issues.
  
  Solution:
  
  Check Existing Objects: Before creating or renaming an object, check the existing objects in the relevant folder or context to ensure that the name you want to use is not already taken.
  Rename the Object: If the name is already in use, consider using a different name that is unique within the context.
  Clear Cache: If you suspect that the issue is due to caching, try clearing the cache or refreshing the view of the objects in the system.
  Use a Naming Convention: Implement a naming convention that includes unique identifiers (like dates, user initials, etc.) to avoid conflicts in the future.
  Check for Hidden Objects: Sometimes, objects may be hidden or not immediately visible. Ensure that you have the necessary permissions to view all objects in the folder.
