  Cause:
  
  Missing Function Module: The function module that is supposed to handle the specified function code for the given object is not defined or does not exist in the system.
  Incorrect Configuration: The configuration for the interface or the function code may be incorrect, leading to the system not being able to locate the appropriate handler.
  Transport Issues: If the function module was recently transported from another system, it may not have been transported correctly or may be missing dependencies.
  Authorization Issues: The user may not have the necessary authorizations to access the function module.
  
  Solution:
  
  Check Function Module: Verify that the function module corresponding to the function code and object exists in the system. You can do this by using transaction SE37 (Function Builder) to search for the function module.
  Review Configuration: Check the configuration settings related to the interface or function code in transaction SPRO or the relevant customizing transaction. Ensure that the function code is correctly mapped to the appropriate function module.
