  Causes:
  
  Missing Function Module: The function module specified in the error message does not exist in the system. This could be due to a missing transport or an incomplete installation.
  Incorrect Naming: The function module name may be misspelled or incorrectly referenced in the code.
  Authorization Issues: The user may not have the necessary authorizations to access the function module.
  System Configuration: The system may not be properly configured, or there may be inconsistencies in the system environment.
  Transport Issues: If the function module was recently transported from another system, the transport may not have been successful.
  
  Solutions:
  
  
  Check Function Module Existence:
  
  Use transaction code SE37 (Function Builder) to check if the function module exists in the system. If it does not exist, you may need to create it or transport it from another system.
