• What is the cause and solution for SAP error message WRF_REF145 - &1 of &2 task(s) started in parallel successfully without failed attempt ?

  The SAP error message WRF_REF145 indicates that a certain number of tasks (in this case, &1 of &2) were started in parallel successfully, but there were no failed attempts recorded. This message typically arises in the context of background processing or parallel processing in SAP, particularly in the area of logistics or materials management.
  Cause:
  
  Parallel Processing: The error message is related to the parallel execution of tasks. It suggests that while the tasks were initiated successfully, there may be an issue with how they are being processed or how the results are being handled.
  Configuration Issues: There may be configuration settings in the SAP system that limit the number of parallel tasks or affect their execution.
  Resource Limitations: The system may be facing resource constraints (e.g., memory, CPU) that prevent tasks from executing as expected.
  Data Issues: There could be issues with the data being processed, such as missing or inconsistent data that prevents the tasks from completing successfully.
  
  Solution:
  
  Check Task Logs: Review the logs for the specific tasks that were started. This can provide insights into what might have gone wrong or if there are any warnings or errors that need to be addressed.
  Adjust Parallel Processing Settings: If the system is configured to limit the number of parallel tasks, consider adjusting these settings to allow for more concurrent processing.
  Monitor System Resources: Use transaction codes like ST02 (buffer management), ST06 (OS monitoring), or SM50 (process overview) to monitor system performance and resource usage.
  Data Validation: Ensure that the data being processed is complete and consistent. Check for any missing or incorrect entries that could be causing issues.
  Re-run the Process: If the tasks were initiated but did not complete successfully, try re-running the process to see if the issue persists.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error message or provide additional troubleshooting steps.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SM37 (job monitoring), SLG1 (application log), and ST22 (dump analysis) to help diagnose issues.
  SAP Community: Engage with the SAP Community or forums to see if other users have encountered similar issues and what solutions they found effective.
  Documentation: Review SAP documentation related to parallel processing and background jobs for best practices and configuration guidelines.
  
  If the issue persists after following these steps, it may be beneficial to reach out to SAP support for further assistance.
