• What is the cause and solution for SAP error message WS684 - Simulation run is not supported for this function ?

  SAP Error Message:
  WS684 - Simulation run is not supported for this function
  
  
  Cause:
  This error occurs when you attempt to execute a simulation run for a function or transaction that does not support simulation mode. In SAP, certain functions or processes are designed to be executed only in actual run mode (real posting or processing) and do not have a simulation or test run capability. Trying to run these functions in simulation mode triggers the WS684 error.
  
  Explanation:
  
  Simulation run means executing a process without making any actual changes to the database or system, often used for testing or validation.
  Some SAP functions, especially those involving complex or critical business processes, do not allow simulation because the system cannot simulate the entire process accurately or because simulation could lead to inconsistent system states.
  The error WS684 explicitly indicates that the function you are trying to simulate does not support this mode.
  
  
  
  Solution:
  
  
  Run the function in actual mode:
  Instead
