• What is the cause and solution for SAP error message /SAPAPO/OM_ERROR2132 - Transactional simulation not active, open first ?

  The SAP error message /SAPAPO/OM_ERROR2132 indicates that a transactional simulation is not active, and it suggests that you need to open it first before proceeding. This error typically occurs in the context of SAP Advanced Planning and Optimization (APO) when users attempt to perform certain operations that require a simulation environment to be active.
  Cause:
  The primary cause of this error is that the user is trying to execute a function or transaction that requires a simulation mode to be active, but it is not currently activated. This can happen if:
  
  The user has not started a simulation session.
  The simulation session has been closed or ended.
  There is a configuration issue in the APO system.
  
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Start a Transactional Simulation:
  
  Navigate to the relevant transaction in SAP APO where you want to perform the simulation.
  Look for an option to start a new simulation session. This is usually found in the menu or toolbar.
  Activate the simulation mode by selecting the appropriate option (e.g., "Start Simulation" or similar).
  
  
  
  Check Simulation Settings:
  
  Ensure that the simulation settings are correctly configured. This may involve checking the parameters or settings in the APO system that govern how simulations are handled.
  
  
  
  Review User Authorizations:
  
  Make sure that the user has the necessary authorizations to start and run simulations in the APO environment.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation or help files related to the specific APO module you are working with for more detailed instructions on how to initiate a simulation.
  
  
  
  Contact Support:
  
  If the issue persists after trying the above steps, consider reaching out to your SAP support team or consulting with SAP support for further assistance.
  
  
  
  Related Information:
  
  Transactional Simulation: This is a mode in SAP APO that allows users to simulate planning scenarios without affecting the actual data. It is essential for testing and validating planning strategies.
