>0521 - Details

• The SAP error message 0521 with the text "** SIMULATION RUN ***" typically indicates that the system is currently in a simulation mode for a particular transaction or process. This means that the system is not executing the actual transaction but is instead simulating the results without making any changes to the database.
  
  Cause:
  
  Simulation Mode Activated: The user or the system has activated the simulation mode for the transaction. This is often done to test the process without affecting actual data.
  Transaction Settings: Certain transactions in SAP have options to run in simulation mode, which can be set in the transaction parameters or user settings.
  User Authorization: Sometimes, the user may not have the necessary authorizations to execute the transaction in a live mode, leading to the system defaulting to simulation.
  
  
  Solution:
  
  Check Simulation Settings: Review the transaction settings to ensure that the simulation mode is not activated unintentionally. Look for any flags or options
