• What is the cause and solution for SAP error message MQ428 - Package &1 was already started; only display possible ?

  The SAP error message MQ428 indicates that a package (in this case, identified by &1) has already been started and is currently in a state where it cannot be started again. This typically occurs in the context of transport management within SAP, where packages are used to group changes for transport between different systems.
  
  Cause:
  
  Package Already Started: The most common cause of this error is that the transport package has already been initiated or is in the process of being transported. SAP does not allow the same package to be started multiple times simultaneously.
  Locking Mechanism: SAP uses a locking mechanism to prevent concurrent modifications or actions on the same transport package, which can lead to inconsistencies.
  User Permissions: Sometimes, the user may not have the necessary permissions to start the package again, leading to this error.
  
  
  Solution:
  
  Check Package Status: Use transaction code SE09 or SE10 to check the status of the transport package.
