• What is the cause and solution for SAP error message E0820 - Not possible to switch to change mode ?

  The SAP error message E0820, "Not possible to switch to change mode," typically occurs when a user attempts to enter change mode in a transaction or program but is unable to do so due to various reasons. Here are some common causes, potential solutions, and related information:
  Causes:
  
  Authorization Issues: The user may not have the necessary authorizations to make changes in the specific transaction or object.
  Object Locking: The object or transaction may be locked by another user or process, preventing changes.
  Transport Request Issues: If the changes are related to a transport request, there may be issues with the transport system or the request may be in a status that does not allow changes.
  System Configuration: Certain system settings or configurations may restrict change mode access.
  Development Environment: If you are in a production environment, the system may be configured to prevent changes to ensure stability.
  
  Solutions:
  
  Check Authorizations: Verify that the user has the necessary authorizations to perform changes. This can be done by checking the user's roles and authorizations in transaction SU53 or SUIM.
  Release Locks: If the object is locked, identify the user or process that has locked it. You can use transaction SM12 to check for locks and release them if necessary.
  Review Transport Requests: If the issue is related to transport requests, check the status of the transport request in transaction SE09 or SE10. Ensure that the request is not in a status that prevents changes (e.g., released).
  Check System Settings: Review the system settings and configurations to ensure that change mode is allowed for the specific transaction or object.
  Development vs. Production: If you are in a production environment, consider whether you need to make changes in a development or quality assurance environment first, and then transport them to production.
