  When creating or saving transport requests or objects that require file references.
  When using SAP GUI file dialogs to select files for upload or download.
  When specifying file names in custom programs or standard SAP transactions that interact with the file system.
  
  
  Solution / How to fix
  
  
  Check the file name:
  
  Ensure the file name is not empty.
  Use only valid characters (avoid special characters like * ? < > | : " / \).
  Make sure the file name length is within allowed limits (usually less than 255 characters).
  
  
  
  Verify the file path:
  
  Confirm the full path is correct and accessible.
  For uploads, ensure the file exists at the specified location.
  For downloads, ensure the target directory exists and you have write permissions.
  
  
  
  Use the SAP file dialog:
  
  Instead of typing the file name manually, use the file selection dialog to avoid typos or invalid paths.
  
  
  
  Check user permissions:
  
  Ensure the user has the necessary OS-level permissions to access the file or directory.
  
  
  
  Check for system restrictions:
  
  Some SAP systems or transactions may restrict file paths for security reasons (e.g., only allow certain directories).
  
  
  
  If using custom code:
  
  Validate the file name and path before passing it to SAP functions.
  Use standard SAP function modules like EPS_GET_DIRECTORY_LISTING or GUI_UPLOAD with proper error handling.
