• What is the cause and solution for SAP error message TR_AUSL191 - Supplement change piece list is not modifiable; request of type &1 exists ?

  The SAP error message TR_AUSL191 indicates that there is an issue with modifying a supplement change piece list because a request of a certain type already exists. This typically occurs in the context of transport requests and change management in SAP systems.
  Cause:
  The error is usually caused by one of the following scenarios:
  
  Existing Transport Request: There is already an existing transport request of the specified type (e.g., workbench request, customizing request) that is preventing modifications to the piece list.
  Locking Mechanism: The system may have a locking mechanism in place that prevents changes to the piece list while another request is being processed.
  Incorrect Status: The piece list may be in a status that does not allow modifications, such as being released or already included in a transport.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Check Existing Requests:
  
  Use transaction code SE09 or SE10 to check for existing transport requests. Look for requests of the same type that might be locking the piece list.
  If you find an existing request, you may need to either wait for it to be processed or work with your team to resolve any issues with that request.
  
  
  
  Release or Delete Requests:
  
  If the existing request is no longer needed, consider releasing or deleting it if you have the necessary authorizations.
  Ensure that you have the correct permissions to make changes to transport requests.
  
  
  
  Check Lock Entries:
  
  Use transaction code SM12 to check for any lock entries that might be preventing modifications. If you find any locks that are no longer valid, you can delete them (with caution).
  
  
  
  Review Transport Management:
  
  Ensure that your transport management settings are correctly configured. Sometimes, issues can arise from misconfigurations in the transport landscape.
  
  
  
  Consult Documentation:
