• What is the cause and solution for SAP error message ECH_PLA_CUSTOM001 - Class &1 does not implement interface &2 ?

  The SAP error message ECH_PLA_CUSTOM001 indicates that a specific class does not implement a required interface. This error typically arises in the context of custom development in SAP, particularly when working with ABAP classes and interfaces.
  Cause:
  
  
  Missing Implementation: The class specified in the error message does not implement the interface that it is supposed to. This could be due to:
  
  The class was created without implementing the required interface.
  The interface was changed or updated, and the class was not updated accordingly.
  There might be a typo in the class or interface name.
  
  
  
  Incorrect Configuration: The configuration or settings in the system may point to a class that is not correctly set up to implement the required interface.
  
  
  Development Errors: If the class was developed by a developer, there might have been an oversight in the implementation of the interface.
  
  
  Solution:
  
  
  Check Class Implementation:
  
  Go to the ABAP Workbench (Transaction SE80 or SE24).
  Open the class mentioned in the error message.
  Check if the class implements the specified interface. If not, you need to implement the interface methods in the class.
  
  
  
  Implement Missing Methods:
  
  If the class does not implement the required methods from the interface, you need to add those methods to the class. Ensure that the method signatures match those defined in the interface.
  
  
  
  Review Changes:
  
  If the interface was recently changed, review the changes and ensure that all classes implementing the interface are updated accordingly.
  
  
  
  Check Configuration:
  
  If the error is related to a configuration setting, verify that the correct class is assigned to the relevant configuration and that it implements the necessary interface.
  
  
  
  Testing:
  
  After making the necessary changes, test the functionality to ensure that the error is resolved.
  
  
  
  Related Information:
  
  Transaction Codes: Use SE80 (Object Navigator) or SE24 (Class Builder) to navigate and modify classes and interfaces.
  Documentation: Review the documentation for the specific interface to understand the methods that need to be implemented.
  Debugging: If the error persists, consider using the debugger to trace where the error occurs in the code execution.
  
  Conclusion:
  The error message ECH_PLA_CUSTOM001 indicates a mismatch between a class and its required interface. By ensuring that the class correctly implements the interface and its methods, you can resolve this issue. Always ensure to test thoroughly after making changes to confirm that the issue is resolved.
