How To Fix APO_BAPI095 - Another transactional simulation is currently being used

SAP Error Message - Details

• Message type: E = Error

• Message class: APO_BAPI - Message Class for APO BAPIs

• Message number: 095

• Message text: Another transactional simulation is currently being used

What causes this issue?

The system attempted to access data in a transactional simulation, or
to open a new transactional simulation. However, this was not possible
as another transactional simulation was already being used in the same
call.

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?

If you perform several calls, check whether a transactional simulation
was set or is already being used in previous calls. For example, this
could be the case if you call this function in a user exit.
If this is the case, you must change the calls so that the system only
works with one transactional simulation.

• What is the cause and solution for SAP error message APO_BAPI095 - Another transactional simulation is currently being used ?

  The SAP error message APO_BAPI095 ("Another transactional simulation is currently being used") typically occurs in the context of SAP Advanced Planning and Optimization (APO) when a user attempts to start a new simulation while another simulation is already active. This is a common issue in environments where multiple users are working with simulations concurrently.
  Cause:
  
  Active Simulation: The primary cause of this error is that a simulation session is already running. SAP APO does not allow multiple simulations to be executed simultaneously to prevent data inconsistencies and conflicts.
  Session Lock: The system may have a lock on the simulation process, which can happen if a previous simulation was not properly closed or if the user session was interrupted.
  User Permissions: In some cases, user permissions or roles may restrict the ability to start new simulations if another user is already using the simulation functionality.
  
  Solution:
  
  Check Active Simulations: Verify if there are any active simulations by checking the simulation status in the APO system. If you find an active simulation that is no longer needed, you can terminate it.
  End Current Simulation: If you are aware of an active simulation that you can end, do so. This can usually be done through the APO interface where you can find options to stop or cancel the simulation.
  Log Out and Log Back In: Sometimes, simply logging out of the SAP system and logging back in can clear session locks and allow you to start a new simulation.
  Wait for Completion: If another user is running a simulation, you may need to wait until they complete their task before you can start your own simulation.
  Contact System Administrator: If the issue persists, it may be necessary to contact your SAP system administrator. They can check for any locks in the database or session management that may be causing the issue.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes in SAP APO, such as /SAPAPO/SDP94 for simulations, to better navigate the system.
  User Roles and Authorizations: Ensure that your user role has the necessary permissions to run simulations. This can be checked with your SAP security team.
  SAP Notes: Check for any relevant SAP Notes or updates that may address known issues related to this error message. SAP frequently releases patches and updates that can resolve bugs or improve functionality.
  
  By following these steps, you should be able to resolve the error and continue with your planning tasks in SAP APO.
