• What is the cause and solution for SAP error message /SAPAPO/OM_TS604 - Method only allowed in transactional simulation ?

  The SAP error message /SAPAPO/OM_TS604 Method only allowed in transactional simulation typically occurs in the context of SAP Advanced Planning and Optimization (APO), particularly when working with the Transportation Planning or Supply Chain Management modules. This error indicates that a certain method or function is being called in a context where it is not permitted, specifically outside of a transactional simulation.
  Cause:
  The error is usually triggered when:
  
  A method that is intended to be used only in a transactional simulation context is invoked in a different context (e.g., in a background job or a non-simulation environment).
  The system is trying to execute a planning function that requires a simulation mode, but the current session or transaction is not set up for that.
  
  Solution:
  To resolve this error, consider the following steps:
  
  
  Check the Context: Ensure that you are executing the method in the correct context. If the method is meant for transactional simulation, make sure you are in a simulation mode.
  
  
  Use Transactional Simulation: If you are trying to run a planning function or method that requires transactional simulation, switch to the appropriate mode. This can typically be done in the planning book or by using specific transaction codes that enable simulation.
  
  
  Review Custom Code: If you are using custom ABAP code or enhancements, review the code to ensure that it is not inadvertently calling the method outside of the allowed context.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific method you are trying to use. It may provide insights into the correct usage and any prerequisites.
  
  
  Check User Authorizations: Ensure that the user executing the transaction has the necessary authorizations to perform actions in transactional simulation.
  
  
  Contact SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for further assistance. They may provide patches or additional insights based on the specific version of your SAP system.
  
  
  Related Information:
  
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide updates and fixes.
  Transaction Codes: Familiarize yourself with transaction codes related to APO and transportation planning, such as /SAPAPO/TS for transportation simulation.
  APO Configuration: Review the configuration settings in your APO system to ensure that they are set up correctly for transactional simulations.
  
  By following these steps, you should be able to identify the cause of the error and implement a suitable solution.
