• What is the cause and solution for SAP error message /ISDFPS/ME_CA_MB004 - This is only a simulation run; no database changes ?

  The SAP error message /ISDFPS/ME_CA_MB004 indicates that the system is currently in a simulation mode, meaning that no actual changes will be made to the database. This is a common scenario in SAP when you are running a transaction or report that is designed to simulate the effects of an action without committing any changes to the database.
  Cause:
  
  Simulation Mode: The transaction or report you are executing is set to run in simulation mode. This is often used for testing purposes to see what would happen if the transaction were executed without actually making any changes.
  Configuration Settings: Certain configurations or parameters may be set to enforce simulation mode for specific transactions or processes.
  
  Solution:
  
  Check Transaction Settings: If you intend to perform an actual update, ensure that you are not in simulation mode. Look for any options or checkboxes in the transaction screen that indicate "Simulation" or "Test Run" and uncheck them.
  Review User Input: Make sure that you are entering the correct parameters for the transaction. Sometimes, specific input values can trigger the simulation mode.
  Consult Documentation: Refer to the SAP documentation or help files related to the specific transaction you are using to understand how to switch from simulation to actual execution.
  Authorization: Ensure that you have the necessary authorizations to perform the action you are trying to execute. Lack of proper authorization might default the system to simulation mode.
  Contact Support: If you are unsure why the system is in simulation mode or if you believe it should not be, consider reaching out to your SAP support team or consulting with an SAP expert.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with the transaction codes related to the process you are working on, as they may have specific settings for simulation.
  SAP Notes: Check SAP Notes for any known issues or updates related to the specific transaction or error message.
  Testing Environment: If you are working in a testing or development environment, it is common for certain transactions to default to simulation mode to prevent unintended changes.
  
  By following these steps, you should be able to resolve the issue and execute the transaction as intended.
