• What is the cause and solution for SAP error message IDOC_ADAPTER664 - No queue entries exist for the inbound tRFC ?

  The SAP error message IDOC_ADAPTER664, which states "No queue entries exist for the inbound tRFC," typically occurs in the context of processing IDocs (Intermediate Documents) in SAP systems. This error indicates that there are no entries in the queue for the inbound transactional Remote Function Call (tRFC) processing, which is necessary for the IDoc to be processed.
  Causes:
  
  
  No IDocs in the Queue: The most straightforward cause is that there are simply no IDocs queued for processing. This could happen if the IDocs have not been generated or if they have already been processed.
  
  
  IDoc Status: The IDocs may be in a status that does not allow them to be processed. For example, if the IDoc is in an error status, it may not be queued for processing.
  
  
  tRFC Configuration Issues: There may be configuration issues with the tRFC settings in the SAP system, preventing the IDocs from being queued correctly.
  
  
  System Performance Issues: If the system is under heavy load or if there are performance issues, it may affect the queuing and processing of IDocs.
  
  
  Network Issues: If the IDocs are being sent from another system, network issues could prevent them from being received and queued.
  
  
  Solutions:
  
  
  Check IDoc Status: Use transaction code WE02 or WE05 to check the status of the IDocs. Ensure that they are in a status that allows processing (e.g., status 30 for "ready for dispatch").
  
  
  Reprocess IDocs: If IDocs are in an error status, you may need to correct the errors and reprocess them. This can be done using transaction code BD87.
  
  
  Check tRFC Queue: Use transaction code SM58 to check the tRFC queue. Look for any entries that may indicate issues with the processing of IDocs.
  
  
  Review Configuration: Ensure that the tRFC settings are correctly configured in the SAP system. This includes checking the RFC destinations and ensuring that they are correctly set up.
  
  
  Monitor System Performance: Check the system performance and ensure that there are no bottlenecks affecting the processing of IDocs. This may involve checking system logs and performance metrics.
  
  
  Network Connectivity: If IDocs are being sent from another system, ensure that there are no network issues preventing the IDocs from being received.
