Smart SAP Assistant

• What is the cause and solution for SAP error message CFD_REGISTRY_CHECK320 - Function Module &1 must be set to invisible as not registered as BAPI ?

  The SAP error message CFD_REGISTRY_CHECK320 indicates that a function module is being used in a context where it is expected to be a BAPI (Business Application Programming Interface), but it is not registered as such. This can occur when a function module is intended to be used in a BAPI context but has not been properly configured or registered in the system.
  Cause:
  
  Function Module Not Registered as BAPI: The function module in question is not registered in the BAPI registry. BAPIs must be explicitly defined and registered to be used in certain contexts, such as in RFC calls or in the BAPI interface.
  Incorrect Usage: The function module is being called in a way that expects it to behave like a BAPI, but it does not meet the necessary criteria or configurations.
  Development Errors: There may be issues in the development of the function module itself, such as missing parameters or incorrect settings.
  
  Solution:
  
  
  Register the Function Module as a BAPI:
  
  Go to transaction BAPI in SAP.
  Use the BAPI Workbench to register the function module as a BAPI.
  Ensure that the function module meets the BAPI requirements, such as having the correct import/export parameters and following the BAPI naming conventions.
  
  
  
  Check Function Module Configuration:
  
  Review the function module in transaction SE37 to ensure it is correctly defined.
  Ensure that it has the necessary import and export parameters and that it follows the BAPI standards.
  
  
  
  Modify the Calling Program:
  
  If the function module is not intended to be a BAPI, modify the calling program to use it in a way that does not expect BAPI behavior.
  Ensure that the calling program is using the correct function module that is registered as a BAPI if that is the intended use.
  
  
  
  Consult Documentation:
  
  Review SAP documentation or notes related to BAPIs and function modules to ensure compliance with best practices.
  
  
  
  Related Information:
  
  BAPI Standards: BAPIs must follow specific standards, including naming conventions, parameter types, and error handling.
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE37 (Function Module), BAPI (BAPI Workbench), and SE80 (Object Navigator) for development and troubleshooting.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on BAPI registration and usage.
  
  By following these steps, you should be able to resolve the CFD_REGISTRY_CHECK320 error and ensure that your function module is correctly registered and used within the SAP environment.
