• What is the cause and solution for SAP error message FL136 - No enhancement currently possible for RFC and update modules ?

  The SAP error message FL136: No enhancement currently possible for RFC and update modules typically occurs when you attempt to enhance a function module that is either an RFC (Remote Function Call) or an update function module. This error indicates that the system does not allow enhancements for these types of function modules due to their specific nature and the potential impact on system performance and integrity.
  Cause:
  
  Function Module Type: The function module you are trying to enhance is defined as an RFC or update function module. SAP restricts enhancements on these types to maintain system stability and performance.
  Enhancement Framework: The enhancement framework in SAP has certain limitations, and RFC/update function modules are not designed to be enhanced in the same way as standard function modules.
  SAP Version: Depending on the version of SAP you are using, there may be specific restrictions on enhancements for certain function modules.
  
  Solution:
  
  
  Alternative Approaches:
  
  Use BAdIs: Instead of enhancing the function module directly, check if there are Business Add-Ins (BAdIs) available that allow you to implement your custom logic without modifying the standard function module.
  User Exits: Look for user exits that may provide the necessary hooks for your custom logic.
  Custom Function Module: If you need to implement specific logic, consider creating a custom function module that wraps around the standard RFC or update function module.
  
  
  
  Review Documentation: Check the SAP documentation for the specific function module to see if there are recommended enhancement points or alternative methods to achieve your requirements.
  
  
  SAP Notes: Search for relevant SAP Notes that may provide additional guidance or updates regarding enhancements for the specific function module you are working with.
  
  
  Consult SAP Support: If you are unable to find a suitable alternative, consider reaching out to SAP Support for assistance or clarification on the best practices for your specific scenario.
