• What is the cause and solution for SAP error message AJ820 - Real update not permitted in simulation run ?

  The SAP error message AJ820: Real update not permitted in simulation run typically occurs when a user attempts to execute a transaction or process that is intended for real data updates while the system is in simulation mode. This is a safeguard to prevent unintended changes to the database during testing or simulation scenarios.
  Cause:
  
  Simulation Mode: The transaction or process is being executed in a mode that is meant for testing or simulation, which does not allow real updates to the database.
  Configuration Settings: The system may be configured to run certain processes in simulation mode by default.
  User Authorization: The user may not have the necessary authorizations to perform real updates, leading the system to default to simulation mode.
  
  Solution:
  
  Check Transaction Mode: Ensure that you are not in simulation mode. Look for any options or flags in the transaction that indicate whether it is set to run in simulation or real mode. If you are in simulation mode, switch to real mode.
  Review Configuration: If the process is intended to run in real mode, check the configuration settings in the relevant transaction or program to ensure it is not set to simulation by default.
  User Authorizations: Verify that you have the necessary authorizations to perform the action. If not, contact your SAP security administrator to obtain the required permissions.
  Testing Environment: If you are in a testing environment and need to perform real updates, ensure that you are in the correct environment (e.g., development or quality assurance) that allows for real updates.
  
  Related Information:
  
  Transaction Codes: Depending on the context, the error may arise in various transaction codes related to financial postings, material movements, or other processes.
