WXP661 - Overview

• 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.

  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
