  The SAP error message SQ027, which states "Parameters for queue & buffered," typically relates to issues with the configuration of the SAP system's queue management, particularly in the context of the SAP Application Interface Framework (AIF) or when dealing with asynchronous processing.
  Cause:
  
  
  Queue Configuration Issues: The error often arises when there are problems with the configuration of the queues in the SAP system. This could be due to missing or incorrect parameters for the queue that is supposed to handle buffered messages.
