• What is the cause and solution for SAP error message FES002 - Cannot perform frontend function in batch input mode ?

  The SAP error message FES002: Cannot perform frontend function in batch input mode typically occurs when a transaction or function that requires user interaction is attempted to be executed in batch input mode. This error indicates that the system is trying to perform a frontend function (like a GUI operation) that is not supported in the context of batch processing.
  Cause:
  
  Batch Input Mode: The error arises because the transaction is being executed in batch input mode, which does not support certain frontend functions that require user interaction, such as file uploads, GUI-based pop-ups, or other interactive elements.
  Transaction Type: Some transactions are designed to be run interactively and cannot be executed in a batch mode.
  Script or Program: If you are using a script or a program that tries to perform frontend operations (like reading from the clipboard, opening a file dialog, etc.) while in batch input mode, this error will occur.
  
  Solution:
  
  Check Transaction Compatibility: Ensure that the transaction you are trying to run is compatible with batch input mode. If it requires user interaction, consider using a different method to achieve your goal.
  Use Background Processing: If possible, switch to a background processing method that does not require frontend interaction. This can be done using background jobs (SM36) or other appropriate methods.
  Modify the Program: If you have access to the ABAP code, modify the program to avoid frontend functions when running in batch input mode. You can check the mode using the sy-batch system variable.
  Use BAPIs or RFCs: If you are trying to perform data updates or transactions, consider using BAPIs (Business Application Programming Interfaces) or RFCs (Remote Function Calls) that are designed for such operations without requiring a frontend.
  Error Handling: Implement error handling in your batch input program to gracefully handle situations where frontend functions are called inappropriately.
