• What is the cause and solution for SAP error message SAP_ACO035 - Class &1 does not implement whitelist provider interface ?

  The SAP error message SAP_ACO035 indicates that a specific class does not implement the required whitelist provider interface. This error typically arises in the context of SAP's Application Interface Framework (AIF) or when dealing with custom classes that are expected to provide certain functionalities related to whitelisting.
  Cause:
  The error occurs when:
  
  A class that is expected to implement the whitelist provider interface does not do so. This can happen if the class is incorrectly defined or if the necessary interface methods are not implemented.
  The class might be missing the required interface or the implementation of the methods defined in that interface.
  There may be a mismatch between the expected interface and the actual class being used.
  
  Solution:
  To resolve the error, you can follow these steps:
  
  
  Check Class Implementation:
  
  Verify that the class mentioned in the error message implements the required whitelist provider interface. You can do this by checking the class definition in the ABAP Workbench (SE80 or SE24).
  Ensure that all methods defined in the interface are correctly implemented in the class.
  
  
  
  Implement Missing Methods:
  
  If the class does not implement the required methods, you will need to add those implementations. Refer to the documentation of the interface to understand what methods need to be implemented.
  
  
  
  Correct Class Assignment:
  
  Ensure that the correct class is being used in the context where the error occurs. If a different class is intended to be used, update the configuration or code to reference the correct class.
  
  
  
  Check for Updates:
  
  If you are using a custom class, ensure that it is up to date with any changes in the SAP system or the interface it is supposed to implement. Sometimes, updates to SAP can change the requirements for interfaces.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation related to the specific interface and the context in which the error occurs. This can provide insights into what is expected from the class.
  
  
  
  Debugging:
  
  If the issue persists, consider debugging the code to trace where the error is being triggered. This can help identify if there are any logical errors in how the class is being used.
