• What is the cause and solution for SAP error message SWF_RUN660 - System error: Method &1->&2 not implemented ?

  The SAP error message SWF_RUN660, which states "System error: Method &1->&2 not implemented," typically occurs in the context of workflow processing. This error indicates that a method that is expected to be implemented in a class or interface is not available or has not been defined. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Missing Implementation: The method referenced in the error message (indicated by &1 and &2) is not implemented in the corresponding class or interface. This can happen if the workflow was designed to call a method that has not been coded.
  Incorrect Configuration: The workflow might be incorrectly configured, pointing to a method that does not exist or is not accessible in the current context.
  Transport Issues: If the workflow was transported from one system to another, the method might not have been included in the transport request.
  Version Mismatch: There may be a version mismatch between the workflow and the underlying classes or methods it relies on.
  
  Solution:
  
  
  Check Method Implementation:
  
  Use transaction SE80 or SE24 to navigate to the class or interface mentioned in the error message.
  Verify if the method is implemented. If not, you may need to implement it or correct the workflow to call a different method.
  
  
  
  Review Workflow Configuration:
  
  Use transaction SWDD (Workflow Builder) to review the workflow definition.
  Ensure that the method being called is correctly configured and that all necessary parameters are being passed.
  
  
  
  Transport Check:
  
  If the workflow was recently transported, check the transport logs to ensure that all necessary objects were included.
  If something is missing, you may need to transport the missing objects.
  
  
  
  Debugging:
  
  If you have access to debugging tools, you can set breakpoints in the workflow to see where the error occurs and gather more context about the failure.
