• What is the cause and solution for SAP error message E0664 - & already has successor & ?

  The SAP error message E0664 typically indicates that there is an issue with the transport request in the SAP system, specifically related to the transport of objects that have already been assigned a successor. This can occur when you are trying to transport a change request that has dependencies or when the transport request is not properly sequenced.
  Cause:
  
  Successor Assignment: The error suggests that the transport request you are trying to work with already has a successor assigned to it. This means that there is another transport request that is dependent on the one you are trying to release or modify.
  Transport Sequence Issues: If the transport requests are not sequenced correctly, it can lead to conflicts and errors when trying to release or import them.
  Object Locking: Sometimes, objects may be locked by other transport requests, leading to this error.
  
  Solution:
  
  Check Transport Request: Review the transport request in question to see if it has a successor. You can do this by using transaction code SE09 or SE10 to view the transport requests and their dependencies.
  Release Successor: If there is a successor transport request, you may need to release that request first before you can proceed with the current one.
  Adjust Dependencies: If the transport requests are incorrectly sequenced, you may need to adjust the dependencies. This can involve changing the order of the requests or reassigning objects to the correct transport request.
  Consult Transport Organizer: Use the Transport Organizer to analyze the transport requests and their relationships. This tool can help you identify any issues with the transport sequence.
  Check for Locks: Ensure that there are no locks on the objects you are trying to transport. You can check for locks using transaction code SM12.
  
  Related Information:
  
  Transport Management System (TMS): Understanding how the TMS works can help you manage transport requests more effectively.
  Transport Logs: Review transport logs for any additional error messages or warnings that may provide more context about the issue.
  SAP Notes: Check SAP Notes for any known issues or patches related to transport errors. SAP frequently updates its knowledge base with solutions to common problems.
