• What is the cause and solution for SAP error message EA164 - '&' IDocs in queue '&' were sent by qRFC to destination '&' ?

  The SAP error message EA164 indicates that there are IDocs (Intermediate Documents) in the queue that have been sent by qRFC (queued Remote Function Call) to a specific destination. This message typically arises in scenarios where IDocs are being processed asynchronously, and there may be issues with the processing of these IDocs.
  Cause:
  
  
  Queue Issues: The IDocs may be stuck in the qRFC queue due to various reasons, such as:
  
  The target system is down or not reachable.
  The processing program in the target system is not running or is encountering errors.
  Network issues preventing communication between systems.
  
  
  
  Configuration Issues: There may be misconfigurations in the qRFC setup or in the IDoc processing settings.
  
  
  Resource Limitations: The target system may be experiencing resource limitations (e.g., memory, CPU) that prevent it from processing the incoming IDocs.
  
  
  Error in IDoc Processing: There may be errors in the IDocs themselves, such as missing mandatory fields or incorrect data formats.
  
  
  Solution:
  
  
  Check the qRFC Queue: Use transaction SMQ1 (for outbound queues) or SMQ2 (for inbound queues) to monitor the status of the queues. Look for any stuck or failed entries.
  
  
  Check Target System: Ensure that the target system is up and running. Check for any issues that may be affecting its ability to process IDocs.
  
  
  Review IDoc Status: Use transaction WE02 or WE05 to review the status of the IDocs. Look for any errors or warnings that may indicate why the IDocs are not being processed.
  
  
  Check Logs: Review the application logs (transaction SLG1) for any error messages related to IDoc processing or qRFC.
  
  
  Reprocess IDocs: If the IDocs are stuck due to errors, you may need to reprocess them. This can be done using transaction BD87 for reprocessing IDocs.
  
  
  Adjust Configuration: If there are configuration issues, review the settings for qRFC and IDoc processing in transaction SM59 (RFC destinations) and WE20 (partner profiles).
  
  
  Monitor System Resources: Check the performance and resource usage of the target system to ensure it can handle the incoming IDocs.
  
  
  Related Information:
  
  IDoc Types: Understand the specific IDoc types being processed and their structure to identify any potential data issues.
  qRFC Documentation: Familiarize yourself with the qRFC documentation in SAP to understand how it works and how to troubleshoot related issues.
  SAP Notes: Check for any relevant SAP Notes that may address known issues or provide additional troubleshooting steps.
  
  By following these steps, you should be able to identify the cause of the EA164 error message and take appropriate action to resolve it.
