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

APO_BAPI095 - Overview

• 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
