• What is the cause and solution for SAP error message /SPE/CP106 - Inbound delivery &1 is already contained in an RFC queue ?

  The SAP error message /SPE/CP106 Inbound delivery &1 is already contained in an RFC queue typically indicates that there is an issue with the processing of an inbound delivery due to it being already queued for processing in a Remote Function Call (RFC) queue. This can happen in scenarios where multiple processes or systems are trying to handle the same inbound delivery simultaneously, leading to conflicts.
  Cause:
  
  Duplicate Processing: The inbound delivery is being processed more than once, possibly due to a retry mechanism or a system error that caused the same delivery to be sent multiple times.
  RFC Queue Issues: The RFC queue may have a stuck or delayed message that is preventing the current processing of the inbound delivery.
  System Configuration: There may be configuration issues in the system that lead to improper handling of inbound deliveries.
  
  Solution:
  
  Check RFC Queue: Use transaction code SM58 to check the status of the RFC queue. Look for any entries related to the inbound delivery in question. If you find any stuck entries, you may need to process or delete them.
  Monitor Background Jobs: Check if there are any background jobs that are processing the inbound deliveries. Ensure that they are not causing conflicts.
  Review Logs: Check the application logs (transaction SLG1) for any additional error messages or warnings that could provide more context about the issue.
  Avoid Duplicate Submissions: Ensure that the inbound delivery is not being submitted multiple times from the source system. Implement checks to prevent duplicate submissions.
  System Restart: In some cases, restarting the relevant application server or the entire SAP system may help clear any temporary issues with the RFC processing.
  Consult SAP Notes: Look for any relevant SAP Notes that may address this specific error or provide patches or updates that could resolve the issue.
