Smart SAP Assistant

• What is the cause and solution for SAP error message SWF_BND_001035 - Class '&1' does not implement the required interface '&2' ?

  The SAP error message SWF_BND_001035 indicates that a class (denoted as &1) does not implement a required interface (denoted as &2). This error typically occurs in the context of SAP Business Workflow or when dealing with Business Object (BO) definitions and their associated methods.
  Cause:
  
  Missing Interface Implementation: The class specified in the error message does not implement the interface that is expected by the workflow or business object. This can happen if the class was modified or if the interface was changed without updating the class accordingly.
  Incorrect Class Assignment: The class assigned to a workflow step or business object might not be the correct one, leading to a mismatch between the expected interface and the actual class.
  Transport Issues: If the class or interface was transported from one system to another, it might not have been transported correctly, leading to inconsistencies.
  
  Solution:
  
  
  Check Class Implementation:
  
  Go to the ABAP Workbench (transaction SE80 or SE24) and check the class &1.
  Ensure that it implements the interface &2. If it does not, you will need to implement the required methods defined in the interface.
  
  
  
  Update Class:
  
  If the class is supposed to implement the interface, add the necessary methods to the class. You can do this by editing the class in the ABAP Workbench and implementing the required methods.
  
  
  
  Verify Workflow Configuration:
  
  Check the workflow configuration to ensure that the correct class is assigned to the workflow step. You can do this in transaction SWDD (Workflow Builder).
  If the class is not the correct one, update the workflow to point to the correct class that implements the required interface.
  
  
  
  Transport Check:
  
  If the issue arose after a transport, verify that all necessary objects (classes, interfaces, etc.) were transported correctly. You may need to re-transport the missing components.
  
  
  
  Testing:
  
  After making the necessary changes, test the workflow or business object to ensure that the error is resolved.

  Documentation: Refer to SAP Help documentation for more details on implementing interfaces and working with workflows.
  
  
  Debugging: If the issue persists, consider using the debugger to trace the workflow execution and identify where the mismatch occurs.
  
  
  By following these steps, you should be able to resolve the SWF_BND_001035 error and ensure that your class correctly implements the required interface.
