Here are the potential causes, solutions, and related information for this error:
  Causes:
  
  File System Permissions: The user under which the SAP system is running may not have the necessary permissions to access the EPS/out directory.
  Directory Does Not Exist: The EPS/out directory may not exist on the file system.

  Solutions:
  
  
  Check Permissions:

  You can use operating system commands (like ls -l on Unix/Linux) to check permissions and chmod to modify them if necessary.
