  Solution:
  To resolve this error, consider the following steps:
  
  
  Check File Mode: Ensure that the file is opened in the correct mode. If you are trying to write to a file, it should be opened in write mode (e.g., OPEN DATASET ... FOR OUTPUT).

  File Permissions: Check the file system permissions for the file you are trying to access. Ensure that the user under which the SAP system is running has the necessary permissions to write to the file.
  
  
  File Path: Verify that the file path is correct and accessible. Ensure that the directory exists and is writable.
  
  
  Error Handling: Implement error handling in your ABAP code to catch and log any issues that arise during file operations. This can help in diagnosing the problem more effectively.
  
  
  Test with Different Modes: If you are unsure about the correct mode, you can test the file operation with different modes to see if the error persists.
  
  
  Related Information:
