• What is the cause and solution for SAP error message MQ901 - Package &1 already started. No change to package type possible ?

  The SAP error message MQ901, which states "Package &1 already started. No change to package type possible," typically occurs in the context of transport management within SAP systems. This error indicates that a transport package (or request) has already been released or started, and therefore, its type cannot be changed.
  Cause:
  
  Transport Package Status: The transport request/package has already been released or is in a status that does not allow for changes to its type (e.g., from a workbench request to a customizing request).
  Incorrect Process: Attempting to change the type of a transport request after it has been released or moved to a different system (e.g., from development to quality assurance).
  System Configuration: There may be restrictions in the system configuration that prevent changes to transport requests once they are in a certain state.
  
  Solution:
  
  Check Transport Request Status: Verify the status of the transport request/package. If it has already been released, you cannot change its type. You can check the status in the Transport Organizer (transaction SE09 or SE10).
  Create a New Transport Request: If you need a different type of transport request, create a new transport request with the desired type and move the necessary objects to this new request.
  Revert Changes (if applicable): If the transport request is still in a modifiable state (not released), you may be able to revert it to a previous state, but this is generally not recommended as it can lead to inconsistencies.
  Consult Documentation: Review SAP documentation or notes related to transport management for any specific guidelines or restrictions that may apply to your version of SAP.
  Contact SAP Support: If you are unable to resolve the issue, consider reaching out to SAP support for assistance, especially if this is impacting your development or transport processes.
