• What is the cause and solution for SAP error message WA655 - Receiver function module & not identified as RFC-compatible ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WA655 Receiver function module & not identified as RFC-compatible
  
  Cause:
  This error occurs when an attempt is made to call a function module remotely (using RFC - Remote Function Call), but the target function module is not defined as RFC-compatible. In SAP, for a function module to be called remotely, it must be explicitly marked as RFC-enabled.
  Common reasons include:
  
  The function module is a normal (local) function module, not an RFC function module.
  The function module is missing the "Remote-Enabled Module" attribute.
  The function module is incorrectly called via RFC interface.
  The function module is not released for remote calls.
  
  
  Explanation:
  
  RFC-compatible function modules are those that can be called from other SAP systems or external programs via RFC.
  To be RFC-compatible, the function module must be created or changed with the "Remote-Enabled Module" attribute in transaction SE37.
  If you try to call a function module remotely that is not RFC-enabled, SAP raises this error.
  
  
  Solution:
  
  
  Check the function module attributes:
  
  Go to transaction SE37.
  Enter the function module name.
  Click on Change.
  Check if the function module is marked as Remote-Enabled Module.
  If not, change the function module to be remote-enabled and save it.
  
  
  
  If you do not have authorization or cannot change the function module:
  
  Contact the developer or responsible team to create an RFC-enabled wrapper function module that internally calls the original function module.
  Use this RFC-enabled wrapper for remote calls.
  
  
  
  Verify the calling program:
  
  Ensure that the calling program or interface is calling the correct RFC-enabled function module.
  Sometimes, a typo or wrong function module name causes this error.
  
  
  
  Transport and activation:
  
  After changing the function module to be remote-enabled, ensure it is activated and transported properly to the target system.
  
  
  
  
  Additional Information:
  
  Transaction SE37: Function Builder, used to create and maintain function modules.
  Remote-Enabled Module: A function module attribute that allows the function module to be called remotely via RFC.
  RFC (Remote Function Call): SAP's protocol for communication between SAP systems or between SAP and external systems.
  Error WA655: This is a runtime error (short dump) indicating the function module is not RFC-compatible.
