• What is the cause and solution for SAP error message TK420 - Request/task &1 (&2) is assigned to a different client ?

  The SAP error message TK420 indicates that a request or task is assigned to a different client than the one you are currently working in. This typically occurs during transport operations, such as when you are trying to release or import a transport request that is not compatible with the current client.
  Cause:
  
  Client-Specific Transport Requests: The transport request you are trying to work with is client-specific, meaning it was created in a different client than the one you are currently logged into.
  Incorrect Client Context: You may be logged into a client that does not have access to the transport request or task you are trying to process.
  Transport Directory Issues: There may be issues with the transport directory or configuration that are causing the system to misidentify the client.
  
  Solution:
  
  Check Client: Ensure that you are logged into the correct client where the transport request was created. You can check the client number in the SAP GUI at the top right corner.
  Use the Correct Transport Request: If you are in the wrong client, switch to the correct client and try to access the transport request again.
  Transport Organizer: Use the Transport Organizer (transaction code SE09 or SE10) to check the status of the transport request and ensure it is assigned to the correct client.
  Transport Configuration: If you suspect a configuration issue, check the transport configuration settings in transaction code STMS. Ensure that the transport routes and directories are correctly set up.
  Consult Basis Team: If the issue persists, consult your SAP Basis team. They can help investigate any underlying issues with the transport system or client configuration.
