• Message class: WD - Workflow definition

• Message number: 293

• Message text: No exception 'Processing obsolete' was modeled for step '&'

What causes this issue?

At step &v1&, the exception <ZH>processing obsolete</> was not modeled.
Therefore step &v1& cannot be modeled as type <ZH>process control</>,
which makes step &v1& obsolete.

• What is the cause and solution for SAP error message WD293 - No exception 'Processing obsolete' was modeled for step '&' ?

  The SAP Web Dynpro error message:
  WD293 No exception 'Processing obsolete' was modeled for step '&'
  
  Cause
  This error occurs during the execution of a Web Dynpro application when the framework encounters a processing step that has become obsolete or invalid, but the application has not defined an exception handler for this specific situation.
  In Web Dynpro, processing steps (like actions, methods, or phases) can throw exceptions. The framework expects that for certain exceptions, the developer has modeled exception handling logic (e.g., in the component controller or the window). If the exception "Processing obsolete" is raised but no exception handler is defined for it in the current step, the framework throws this error.
  The placeholder & in the message is replaced by the name of the step where the exception occurred.
  Typical scenarios causing this:
  
  The user navigated away or the UI element was refreshed, making the current processing step invalid.
  The application logic or UI state changed asynchronously, invalidating the current processing context.
  A backend call or action was canceled or became obsolete due to user interaction or system state changes.
  The Web Dynpro component or view lifecycle is out of sync with the user interaction.
  
  
  Solution
  
  
  Model Exception Handling for 'Processing obsolete'
  
  In the Web Dynpro component or view where the step is defined, explicitly model an exception handler for the exception Processing obsolete.
  This can be done in the Web Dynpro development environment (SE80 or Eclipse-based Web Dynpro tools):
  
  Open the component/view controller.
  Go to the Exception Handling tab.
  Add a handler for the exception Processing obsolete.
  Define the handling logic, which might be to ignore the exception, refresh the UI, or show a message to the user.
  
  
  
  
  
  Check and Adjust UI Flow
  
  Review the UI flow and user interaction to avoid situations where processing steps become obsolete.
  For example, disable buttons or inputs while processing is ongoing.
  Avoid long-running synchronous calls that might be canceled or invalidated by user actions.
  
  
  
  Synchronize Backend and Frontend
  
  Ensure that backend calls and frontend UI states are synchronized.
  Use proper state management to avoid obsolete processing steps.
  
  
  
  Update Web Dynpro Framework / Patches
  
  Sometimes, this error can be caused by bugs in the Web Dynpro framework.
  Check SAP Notes for your SAP NetWeaver version for any relevant patches or fixes.
