• What is the cause and solution for SAP error message PE648 - Function module not executable in batch ?

  The SAP error message PE648 ("Function module not executable in batch") typically occurs when a function module is called in a batch processing context (like a background job) but is not designed to be executed in that environment. This can happen for several reasons, including:
  Causes:
  
  User Interaction Required: The function module may require user interaction (e.g., dialog boxes, user input) that cannot be provided in a batch job.
  Screen I/O: The function module might be trying to perform screen I/O operations, which are not allowed in batch processing.
  Authorization Checks: Some function modules may have authorization checks that are not valid in a batch context.
  Environment Restrictions: Certain operations may be restricted in a batch environment due to system settings or configurations.
  
  Solutions:
  
  Check Function Module: Review the function module's code to determine if it is designed for batch processing. Look for any calls to screen-related functions or user interaction.
  Use Alternative Function Modules: If the function module is not suitable for batch processing, look for alternative function modules that are designed to be executed in the background.
  Modify the Logic: If you have access to the code, consider modifying the logic to remove any dependencies on user interaction or screen I/O.
  Run in Dialog Mode: If the function module must be executed in a dialog context, consider running the job in dialog mode instead of batch mode, if feasible.
  Check Authorizations: Ensure that the user executing the batch job has the necessary authorizations to run the function module.
  
  Related Information:
  
  Transaction Codes: You can use transaction codes like SE37 (Function Builder) to analyze the function module and see its attributes.
  Documentation: Check the SAP documentation for the specific function module to understand its intended use and any limitations regarding batch processing.
