How To Fix WXP661 - No class processing run in the simulation mode

SAP Error Message - Details

• Message type: E = Error

• Message class: WXP - Retail Planning

• Message number: 661

• Message text: No class processing run in the simulation mode

What causes this issue?

You simulated the creation of a promotion. When creating a real
promotion, the class system must be processed or generated. This was
not done in the simulation so that error messages are included in the
log when the promotion is actually created.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

• What is the cause and solution for SAP error message WXP661 - No class processing run in the simulation mode ?

  Certainly! Here's a detailed explanation for the SAP error message WXP661: No class processing run in the simulation mode:
  
  Error Message
  WXP661: No class processing run in the simulation mode
  
  Cause
  This message typically occurs in the context of SAP Workflow or Business Rule Framework plus (BRFplus) when you attempt to simulate or test a workflow or rule that involves class processing, but no class processing run has been executed in simulation mode.
  More specifically:
  
  The system expects a class processing run (e.g., a method or class execution) to be performed during simulation/testing.
  However, no such run has been triggered or recorded.
  This can happen if you try to simulate a workflow or rule without properly executing the class logic or if the simulation environment is not set up correctly to run the class processing.
  
  
  When does it occur?
  
  During workflow simulation in transaction SWUS or SWI1.
  During BRFplus rule simulation where class methods are involved.
  When testing or debugging workflows that use ABAP classes for processing.
  When the simulation mode is active but the class processing step is skipped or not executed.
  
  
  Solution
  
  
  Execute the class processing run in simulation mode:
  
  Ensure that during simulation/testing, the class methods or processing steps are actually executed.
  In workflow simulation, trigger the workflow step that calls the class method.
  In BRFplus, make sure the rule or expression that calls the class method is executed during simulation.
  
  
  
  Check the simulation setup:
  
  Verify that the simulation mode is correctly activated.
  Confirm that the workflow or rule is correctly configured to call the class processing logic.
  If you are using a custom class, ensure it is properly implemented and accessible in the simulation environment.
  
  
  
  Debug the simulation:
  
  Use the debugger to check if the class method is being called during simulation.
  If not, adjust the workflow or rule configuration to ensure the class processing is triggered.
  
  
  
  Check authorization and system settings:
  
  Sometimes missing authorizations or system restrictions can prevent class processing runs.
  Verify that the user has the necessary permissions to execute the class methods.
  
  
  
  Review SAP Notes and documentation:
  
  Check for any SAP Notes related to WXP661 for your specific SAP version.
  Sometimes patches or corrections are available if this is a known issue.

  SAP Workflow (SWF) and Simulation:
  
  Workflow simulation is used to test workflows without affecting live data.
  Class processing in workflows involves calling ABAP classes/methods to perform business logic.
  
  
  
  BRFplus and Class Processing:
  
  BRFplus rules can call ABAP classes for complex logic.
  Simulation mode in BRFplus allows testing rules without committing changes.
  
  
  
  Transactions:
  
  SWUS - Workflow simulation.
  SWI1 - Workflow log.
  BRFplus - Business Rule Framework plus (transaction BRF+).
  
  
  
  Debugging Tips:
  
  Set breakpoints in the class methods.
  Check workflow logs for errors or missing steps.
  Use transaction SWI2_FREQ to analyze workflow errors.
