• What is the cause and solution for SAP error message C0655 - Called function module & is not defined ?

  The SAP error message C0655, which states "Called function module & is not defined," typically occurs when a program or function module attempts to call another function module that does not exist in the system. This can happen for several reasons, including:
  Causes:
  
  Function Module Not Created: The function module being called has not been created or activated in the SAP system.
  Incorrect Name: There may be a typo or incorrect name in the function module call.
  Transport Issues: If the function module was recently transported from another system, it may not have been imported correctly.
  Authorization Issues: The user may not have the necessary authorizations to access the function module.
  Namespace Issues: The function module might be in a different namespace that is not accessible from the current context.
  
  Solutions:
  
  
  Check Function Module Existence:
  
  Use transaction code SE37 (Function Builder) to check if the function module exists. Enter the name of the function module and see if it is available.
  
  
  
  Correct the Name:
  
  Verify the spelling and case of the function module name in the code. Ensure that it matches exactly with the defined function module.
  
  
  
  Transport Check:
  
  If the function module was recently transported, check the transport logs to ensure it was imported successfully. You can use transaction code SE09 or SE10 to review transport requests.
  
  
  
  Authorization Check:
  
  Ensure that the user has the necessary authorizations to execute the function module. You can check this with transaction SU53 after the error occurs.
  
  
  
  Namespace Verification:
  
  If the function module is in a different namespace, ensure that the calling program has access to that namespace.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can set breakpoints in the calling program to see the exact point of failure and gather more context about the error.
