  • Show details Hide details
  • What causes this issue?

    You want to execute an update (COMMIT) or a ROLLBACK. However, there is
    no transactional simulation open in the current mode that could be
    updated or rolled back.

    System Response

    The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

    How to fix this error?

    The function used (BAPI) may only be called if a transactional
    simulation is to be updated or rolled back. Check your scenario to see
    in what sequence functions (BAPIs) should be called.
    Have functions (BAPIs) already been called that have opened a
    transactional simulation?
    Has the update or ROLLBACK been called several times so that no more
    transactional simulations are available?

  • What is the cause and solution for SAP error message APO_BAPI178 - No transactional simulations are open ?
    The SAP error message APO_BAPI178: No transactional simulations are open typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to perform an operation that requires an active simulation, but no such simulation is currently open.
    
    Cause: No Active Simulation: The most common cause of this error is that there are no active transactional simulations available in the system. This can happen if the user has not started a simulation or if all simulations have been closed. Session Management: The user may have inadvertently closed the simulation session or navigated away from it. Authorization Issues: In some cases, the user may not have the necessary authorizations to access or create a simulation.
    Solution: Start a New Simulation: Navigate to the relevant transaction in APO (e.g., SNP, DP) and create a new simulation. Ensure that you follow the correct steps to initiate a simulation. In the planning book or the relevant application, look
