• What is the cause and solution for SAP error message C$710 - Function &: No export parameter & ?

  The SAP error message C$710, which states "Function &: No export parameter &," typically occurs when a function module is called without the required export parameters being defined or passed correctly. This can happen in various scenarios, such as when a custom function module is invoked, or when there is a mismatch between the calling program and the function module's definition.
  Cause:
  
  Missing Export Parameter: The function module being called expects certain export parameters that are not being provided in the call.
  Incorrect Function Module Signature: The function module may have been changed (e.g., parameters added or removed) after the calling program was written, leading to a mismatch.
  Typographical Errors: There may be a typo in the function module name or in the parameter names being passed.
  Authorization Issues: Sometimes, authorization issues can prevent the function module from being executed properly, leading to misleading error messages.
  
  Solution:
  
  
  Check Function Module Definition: Go to transaction SE37 (Function Builder) and check the definition of the function module being called. Ensure that all required export parameters are defined and that their names match what is being passed in the calling program.
  
  
  Update Calling Program: If the function module has been modified, update the calling program to ensure that it passes all required parameters correctly.
  
  
  Parameter Mapping: Ensure that the parameters being passed to the function module match the expected types and names. Pay attention to the order and data types of the parameters.
  
  
  Debugging: Use the debugger to step through the code where the function module is called. This can help identify if the parameters are being populated correctly before the call.
  
  
  Check for Authorization Issues: Ensure that the user executing the program has the necessary authorizations to call the function module.
  
  
  Consult Documentation: If the function module is part of a standard SAP package, consult the SAP documentation or notes for any changes or requirements related to that function module.
  
  
  Related Information:
  
  Transaction Codes: SE37 (Function Builder), SE80 (Object Navigator), SE11 (Data Dictionary).
  SAP Notes: Check for any relevant SAP Notes that might address known issues with the specific function module.
  Function Module Documentation: Review the documentation associated with the function module for any specific requirements or examples of usage.
  
  By following these steps, you should be able to identify the cause of the error and implement a solution to resolve it.
