• What is the cause and solution for SAP error message ATP_BOP_LOGIC018 - Simulation mode is active. ?

  The SAP error message ATP_BOP_LOGIC018, which states "Simulation mode is active," typically occurs in the context of Advanced Planning and Optimization (APO) or similar planning scenarios in SAP. This message indicates that the system is currently in simulation mode, which means that no actual changes will be made to the data or planning results. Instead, the system is only simulating the planning process.
  Cause:
  
  Simulation Mode Activated: The most common cause of this error is that the planning run is set to simulation mode. This is often done to test scenarios without affecting actual data.
  User Settings: The user may have inadvertently set the planning run to simulation mode in their user profile or during the planning run setup.
  System Configuration: The system may be configured to default to simulation mode for certain planning runs.
  
  Solution:
  
  Check Planning Run Settings: Review the settings of the planning run you are executing. Ensure that the option for simulation mode is disabled if you want to perform an actual planning run.
  User Profile Settings: Check your user profile settings in SAP. If simulation mode is set as a default, you may want to change it to allow for actual planning runs.
  Consult Documentation: Refer to the SAP documentation or help files related to the specific planning tool you are using (e.g., SAP APO, SAP IBP) to understand how to toggle between simulation and actual modes.
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to your SAP support team or consulting SAP Notes for any known issues or patches related to this error.
  
  Related Information:
  
  Simulation Mode: This mode is useful for testing and validating planning scenarios without impacting live data. It allows users to analyze the potential outcomes of different planning strategies.
  Planning Runs: In SAP APO, planning runs can be configured to execute various planning tasks, including demand planning, supply network planning, and production planning.
  User Authorization: Ensure that you have the necessary authorizations to change the planning run settings, as some users may have restricted access.
  
  By following these steps, you should be able to resolve the ATP_BOP_LOGIC018 error and proceed with your planning activities in SAP.
