• What is the cause and solution for SAP error message /SAPAPO/SOR402 - SIMULATION MODE. No Changes Made ?

  The SAP error message /SAPAPO/SOR402 SIMULATION MODE. No Changes Made typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when working with the Supply Network Planning (SNP) or Production Planning and Detailed Scheduling (PP/DS) modules. This message indicates that the system is currently in simulation mode, and as a result, no changes are being applied to the planning data.
  Cause:
  
  Simulation Mode: The system is set to simulation mode, which is intended for testing and analysis purposes. In this mode, any changes or adjustments made during the planning run are not saved to the database.
  Planning Run Settings: The settings for the planning run may have been configured to run in simulation mode intentionally, either by the user or as part of a standard operating procedure.
  User Authorization: The user may not have the necessary authorizations to execute changes in the planning run, leading to the system defaulting to simulation mode.
  
  Solution:
  
  
  Check Planning Run Settings: Review the settings of the planning run to ensure that it is not set to simulation mode. If you want to make actual changes, you need to run the planning process in "live" mode.
  
  Navigate to the planning run configuration and ensure that the "Simulation" checkbox is unchecked.
  
  
  
  Execute in Live Mode: If you are ready to apply changes, execute the planning run in live mode. This typically involves selecting the appropriate options in the planning run transaction or customizing settings.
  
  
  User Authorizations: Ensure that the user executing the planning run has the necessary authorizations to make changes. If not, contact your SAP security administrator to review and adjust the user roles and permissions.
  
  
  Review Documentation: Consult the SAP documentation or help resources for specific instructions on how to configure and execute planning runs in your version of SAP APO.
  
  
  Related Information:
