• What is the cause and solution for SAP error message /SAPAPO/DEPL_MESS602 - SIMULATION MODE. No Changes Made ?

  The SAP error message /SAPAPO/DEPL_MESS602 indicates that the system is in "Simulation Mode," which means that no actual changes are being made to the data during the planning or deployment process. This is a common scenario in SAP Advanced Planning and Optimization (APO) when users want to test or simulate changes without affecting the live data.
  Cause:
  
  Simulation Mode Activated: The most common cause of this error is that the planning run or deployment is set to simulation mode. This is often done intentionally to analyze the impact of changes without committing them.
  User Settings: The user may have selected options that default to simulation mode.
  Configuration Settings: The system may be configured to run in simulation mode for certain scenarios or processes.
  
  Solution:
  
  
  Check Simulation Mode Settings: 
  
  If you want to make actual changes, ensure that the simulation mode is turned off. This can usually be done in the planning or deployment transaction by unchecking the "Simulation" option.
  
  
  
  Review User Parameters: 
  
  Check if there are user-specific settings that default to simulation mode. You can adjust these settings in the user profile or during the planning run setup.
  
  
  
  Transaction Codes: 
  
  If you are using a specific transaction code (like /SAPAPO/DP for demand planning or /SAPAPO/SDP94 for supply network planning), ensure that you are not inadvertently selecting a simulation option.
  
  
  
  Consult Documentation: 
  
  Review the relevant SAP documentation or help files for the specific transaction you are using to understand how to toggle between simulation and actual execution modes.
  
  
  
  Testing Environment: 
  
  If you are in a testing environment, confirm that the system is not set to always run in simulation mode for safety reasons.
  
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional context on simulation mode behavior.
  User Training: Ensure that users are trained on the implications of simulation mode and how to switch between simulation and actual execution.
  System Logs: Review system logs for any additional messages or warnings that might provide more context about why the system is in simulation mode.
  
  By following these steps, you should be able to resolve the /SAPAPO/DEPL_MESS602 error and proceed with your planning or deployment activities in SAP APO.
