• What is the cause and solution for SAP error message WA660 - Check function module & not found ?

  The SAP error message WA660 Check function module & not found typically indicates that the system is trying to call a function module whose name is either incorrect, missing, or not available in the current system/client.
  
  Cause:
  
  The function module name referenced in the program or configuration is incorrect or does not exist.
  The function module might be custom-developed and not transported to the current system.
  There could be a typo or missing entry in the configuration or code where the function module is called.
  The function module might belong to a specific add-on or component that is not installed or activated in the system.
  Sometimes, the function module name is dynamically determined, and the logic to determine it is failing or returning an empty or wrong name.
  
  
  Solution:
  
  
  Identify the Function Module Name:
  
  The error message usually shows the function module name after the "&" symbol. Check the exact name that is missing.
  If the name is not visible, check the short dump (transaction ST22) or the program code where the function module is called.
  
  
  
  Check Function Module Existence:
  
  Use transaction SE37 to check if the function module exists in the system.
  If it does not exist, verify if it should be a standard SAP function module or a custom one.
  
  
  
  Correct the Function Module Name:
  
  If the name is wrong, correct it in the program or configuration.
  If the function module name is dynamically determined, debug the program to find out why the name is incorrect or missing.
  
  
  
  Transport or Create the Function Module:
  
  If the function module is custom and missing, transport it from the development system or create it if necessary.
  
  
  
  Check System Components and Add-ons:
  
  Verify if the required SAP components or add-ons that provide the function module are installed and active.
  
  
  
  Check Authorizations:
  
  Sometimes, missing authorizations can cause the system to behave as if the function module is missing. Ensure the user has the necessary authorizations.
