  SAP Error Message:
  WS_TOOL109 Could not delete generated class &1
  
  Cause:
  This error occurs when the SAP system tries to delete a generated class (usually a runtime-generated class related to Web Dynpro or other generated objects) but fails. The failure can be due to several reasons:
  
  The generated class is currently in use or locked by another user or process.
  The class is protected or has dependencies that prevent deletion.
  Insufficient authorizations to delete the class.
  The class is part of a transport request that is locked or not released.
  System inconsistencies or database locks.
  
  
  Solution:
  To resolve the error WS_TOOL109, you can try the following steps:
  
  
  Check if the class is in use:
  
  Ensure no active sessions or users are using the generated class.
  Use transaction SE80 or SE24 to check the class status.
  If the class is locked, try to unlock it via SE03 or ask the user holding the lock to release it.
  
  
  
  Check authorizations:
  
  Verify that you have the necessary authorizations to delete or modify generated classes.
  Authorization objects related to class maintenance and Web Dynpro development might be relevant.
  
  
  
  Delete manually:
  
  Try to delete the generated class manually via SE24 or SE80.
  If the class is part of a Web Dynpro component, try regenerating or deleting the component and its generated objects.
  
  
  
  Check transport requests:
  
  If the class is part of a transport request, ensure the transport is not locked or released.
  Use transaction SE09 or SE10 to check transport status.
  
  
  
  Use report or program to clean generated classes:
  
  Sometimes SAP provides standard reports or programs to clean up generated classes or runtime objects.
  For Web Dynpro, you can use report WD_REG_CLEANUP to clean up generated runtime objects.
  
  
  
  System restart or work process reset:
  
  If the class is locked due to system locks or work process issues, a system restart or work process reset might help.
  
  
  
  Check OSS Notes:
