• What is the cause and solution for SAP error message W0100 - RFC destination set but function module is empty ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  W0100 RFC destination set but function module is empty
  
  
  Cause:
  This warning message occurs when an RFC (Remote Function Call) destination is specified in the function call, but the function module name itself is not provided or is empty.
  In other words, the system expects a function module name to be called remotely via the RFC destination, but the function module parameter is missing or blank.
  
  When does it occur?
  
  When calling an RFC-enabled function module programmatically (e.g., via CALL FUNCTION statement) and specifying the DESTINATION parameter, but the FUNCTION parameter (function module name) is empty.
  This can happen due to programming errors, incorrect variable assignments, or missing input data.
  
  
  
  Solution:
  
  
  Check the function module name:
  
  Ensure that the function module name passed in the CALL FUNCTION statement is not empty.
  Example:CALL FUNCTION lv_function_module
    DESTINATION lv_destination
    ...
  Here, lv_function_module must contain a valid function module name.
