  The SAP error message AQV191, which states "An additional field with this name already exists," typically occurs in the context of data modeling or configuration within SAP systems, particularly when working with data sources, InfoObjects, or similar components in SAP BW (Business Warehouse) or SAP HANA.
  Cause:
  This error usually arises when you attempt to create or add a field (such as an InfoObject or a characteristic) that has the same name as an existing field in the system. The system enforces uniqueness for field names to avoid confusion and ensure data integrity.
  Solution:
  To resolve the AQV191 error, you can take the following steps:

  Rename the New Field: 
  
  If you find that the field name you are trying to use is already taken, consider renaming your new field to something unique that does not conflict with existing names.
  
  
  
  Delete or Modify Existing Field: 
  
  If the existing field is no longer needed, you may consider deleting it or modifying its name if it is permissible within your project or system guidelines. Be cautious with this approach, as it may affect other parts of your system.
  
  
  
  Check for Transport Issues: 
  
  If you are working in a development environment and transporting objects to a production environment, ensure that there are no conflicts due to transport requests that may have introduced duplicate field names.
