• What is the cause and solution for SAP error message MPE_AHF_CUST002 - Using an empty executer class deactivates the AHF. See long text ?

  The SAP error message MPE_AHF_CUST002 indicates that an empty executor class has been defined for the Advanced Hierarchy Framework (AHF), which leads to the deactivation of the AHF functionality. This error typically arises when the system expects a valid executor class to be defined for processing but finds that the class is either empty or not properly implemented.
  Cause:
  
  Empty Executor Class: The primary cause of this error is that the executor class defined in the configuration is empty or does not contain the necessary methods and logic to execute the required functionality.
  Configuration Issues: There may be issues in the configuration settings where the executor class is defined, leading to the system not recognizing it as valid.
  Custom Development: If there has been custom development related to the AHF, it is possible that the custom executor class was not implemented correctly.
  
  Solution:
  
  Check Executor Class: Review the executor class that has been defined in the AHF configuration. Ensure that it is not empty and contains the necessary methods and logic to perform its intended function.
  Implement Required Methods: If the executor class is a custom implementation, make sure that all required methods are implemented correctly. This may include methods for data retrieval, processing, and any other necessary functionality.
  Configuration Review: Go through the configuration settings in the AHF to ensure that the correct executor class is assigned and that there are no typos or misconfigurations.
  Testing: After making the necessary changes, test the AHF functionality to ensure that it is working as expected and that the error message no longer appears.
  Consult Documentation: Refer to SAP documentation or notes related to the AHF and executor classes for any specific requirements or guidelines that need to be followed.
