• What is the cause and solution for SAP error message TN721 - No authorization to write to '&1' on the application server ?

  The SAP error message TN721 indicates that a user does not have the necessary authorization to write to a specified file or directory on the application server. This can occur in various scenarios, such as when trying to generate output files, logs, or any other data that needs to be written to the server's file system.
  Cause
  The primary causes of the TN721 error message include:
  
  Insufficient Authorizations: The user does not have the required authorizations to write to the specified file or directory.
  File System Permissions: The operating system permissions for the directory or file do not allow the SAP application server to write to it.
  Incorrect File Path: The specified path may be incorrect or the file may not exist, leading to an inability to write.
  User Role Configuration: The user role may not be properly configured to include the necessary authorizations for file operations.
  
  Solution
  To resolve the TN721 error, you can take the following steps:
  
  
  Check User Authorizations:
  
  Use transaction code SU53 immediately after the error occurs to check the authorization check that failed.
  Ensure that the user has the necessary authorizations for the relevant object (e.g., S_DATASET for file access).
  
  
  
  Review and Adjust Authorizations:
  
  If the user lacks the necessary authorizations, you may need to adjust their roles or profiles. This can be done using transaction code PFCG to modify the user roles and add the required authorizations.
  
  
  
  Check File System Permissions:
  
  Log in to the application server and check the file system permissions for the directory or file in question. Ensure that the user under which the SAP application server is running has write permissions.
  You can use commands like ls -l (on Unix/Linux) to check permissions and chmod to modify them if necessary.
