• What is the cause and solution for SAP error message WE023 - Create function module for editor functions etc. ?

  Certainly! Here's a detailed explanation regarding the SAP error message WE023:
  
  SAP Error Message: WE023
  Message Text:
  
  Create function module for editor functions etc.
  
  Cause
  The error message WE023 typically occurs when you are working with IDoc processing in SAP and the system expects a function module to be created or assigned for certain editor functions related to IDoc processing, but it is missing or not properly maintained.
  More specifically:
  
  When you try to process or edit IDocs using the IDoc editor or related tools, SAP requires certain function modules to handle editor functions (like display, change, or processing of IDocs).
  If these function modules are not created, assigned, or maintained in the system, the system throws the WE023 error.
  This can happen if the system is not fully configured for IDoc processing or if custom function modules are expected but not yet implemented.
  
  
  Solution
  To resolve the WE023 error, follow these steps:
  
  
  Check the Function Module Assignment:
  
  Go to transaction WE41 (for outbound process codes) or WE42 (for inbound process codes).
  Verify if the function modules for the relevant process codes are correctly assigned.
  If the function module is missing, create or assign the appropriate function module.
  
  
  
  Create the Required Function Module:
  
  If the function module does not exist, you need to create it.
  The function module should follow the interface and standards expected by SAP for IDoc processing.
  Usually, these function modules are of type IDOC_INBOUND_ASYNCHRONOUS or similar, depending on the processing scenario.
  
  
  
  Use Standard SAP Function Modules:
  
  If you are unsure about the function module to use, check SAP standard function modules for IDoc processing.
  For example, standard function modules like IDOC_INPUT_<message_type> are used for inbound processing.
  
  
  
  Maintain the Editor Functions:
  
  If the error relates to editor functions (like display or change), ensure that the function modules for these editor functions are created and assigned.
  You can check the customizing for IDoc editor functions in transaction WE20 or related customizing paths.
  
  
  
  Check SAP Notes and Documentation:
  
  Sometimes, specific SAP Notes provide corrections or instructions for this error.
  Search the SAP Support Portal for notes related to WE023.

  Proper assignment and creation of these function modules are critical for smooth IDoc processing.
  
  
  
  Common Scenarios:
  
  Custom IDoc message types requiring custom function modules.
  Missing or incorrectly assigned function modules after system upgrade or transport.
