• What is the cause and solution for SAP error message SC123 - Function module & has dynamic calls and customer functions ?

  The SAP error message SC123, which states "Function module & has dynamic calls and customer functions," typically indicates that there is an issue with a function module that is being called dynamically, and it may involve custom code or enhancements that are not behaving as expected.
  Cause:
  
  
  Dynamic Calls: The function module in question is being called dynamically, which means that the name of the function module is determined at runtime rather than being hard-coded. This can lead to issues if the function module does not exist or if there are problems with the parameters being passed.
  
  
  Customer Functions: The error may also arise from custom enhancements or modifications made to standard SAP function modules. If these custom functions are not implemented correctly or if they conflict with standard functionality, it can lead to errors.
  
  
  Missing or Incorrect Configuration: Sometimes, the function module may rely on certain configurations or settings that are missing or incorrect, leading to runtime errors.
  
  
  Authorization Issues: The user executing the function may not have the necessary authorizations to execute the function module or access certain data.
  
  
  Solution:
  
  
  Check Function Module Name: Verify that the function module being called dynamically exists and is correctly spelled. You can do this by checking in transaction SE37 (Function Builder).
  
  
  Review Custom Code: If there are custom enhancements or modifications, review the code for any errors or inconsistencies. Ensure that the custom logic is correctly implemented and does not interfere with standard functionality.
  
  
  Debugging: Use the debugger to step through the code and identify where the error occurs. This can help pinpoint the exact cause of the issue.
  
  
  Check Parameters: Ensure that the parameters being passed to the function module are correct and in the expected format. Mismatched data types or missing parameters can lead to runtime errors.
  
  
  Authorization Check: Verify that the user has the necessary authorizations to execute the function module. You can check this in transaction SU53 (Authorization Check) after the error occurs.
  
  
  Consult Documentation: Review the SAP documentation for the specific function module to understand its requirements and any dependencies it may have.
  
  
  SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address known issues with the function module or provide guidance on resolving the error.
  
  
  Testing in a Development Environment: If possible, replicate the issue in a development or test environment to troubleshoot without affecting production data.
