• What is the cause and solution for SAP error message SAP_ACO032 - Function Module &1 Parameter &2 not allowed with SAP ACO ?

  The SAP error message SAP_ACO032 indicates that a specific function module parameter is not allowed when using the SAP Application Control (ACO) framework. This error typically arises when there is a mismatch between the expected parameters of a function module and the parameters that are being passed to it, particularly in the context of ACO.
  Cause:
  
  
  Invalid Parameter Usage: The function module being called has parameters that are not compatible with the ACO framework. This could be due to:
  
  The parameter being marked as optional or not intended for use with ACO.
  The parameter type not being supported by ACO.
  Incorrect configuration or implementation of the function module.
  
  
  
  Configuration Issues: There may be issues in the configuration of the ACO settings or the function module itself, leading to the error.
  
  
  Version Mismatch: If the function module has been updated or changed in a way that affects its parameters, and the ACO settings have not been updated accordingly, this error can occur.
  
  
  Solution:
  
  
  Review Function Module Parameters: Check the definition of the function module in transaction SE37 or SE80. Ensure that the parameters being passed are valid and allowed for use with ACO.
  
  
  Modify ACO Configuration: If the function module is intended to be used with ACO, ensure that the ACO configuration is set up correctly to accommodate the parameters of the function module.
  
  
  Update Code: If you are calling the function module in your ABAP code, ensure that you are only passing the parameters that are allowed. Remove or modify any parameters that are causing the error.
  
  
  Consult Documentation: Refer to the SAP documentation for ACO and the specific function module to understand the expected parameters and their usage.
  
  
  Testing: After making changes, test the function module call again to ensure that the error is resolved.
  
  
  Related Information:
  
  Transaction Codes: Use transaction codes like SE37 (Function Builder) and SE80 (Object Navigator) to analyze and modify function modules.
  SAP Notes: Check for any relevant SAP Notes that might address known issues or provide patches related to the function module or ACO.
  Debugging: If the issue persists, consider using the debugger to step through the code and identify where the parameters are being incorrectly set or passed.
  
  If you continue to experience issues, it may be beneficial to reach out to SAP support or consult with a technical expert familiar with ACO and the specific function module in question.
