• What is the cause and solution for SAP error message P99B083 - Call of parallel task rejected ?

  The SAP error message P99B083: Call of parallel task rejected typically occurs when there is an issue with the parallel processing of tasks in the SAP system. This error can arise due to various reasons, including system resource limitations, configuration issues, or problems with the specific task being executed.
  Causes:
  
  Resource Limitations: The system may be running out of resources (e.g., memory, CPU) to handle additional parallel tasks.
  Configuration Settings: The settings for parallel processing in the SAP system may not be configured correctly, leading to task rejection.
  Task Overload: Too many parallel tasks may be initiated at once, exceeding the allowed limit.
  System Locking: If a task is trying to access a resource that is locked by another process, it may be rejected.
  Background Job Issues: If the error occurs during the execution of background jobs, there may be issues with the job configuration or scheduling.
  
  Solutions:
  
  Check System Resources: Monitor the system's performance and resource usage. Ensure that there are enough resources available for parallel processing.
  Adjust Parallel Processing Settings: Review and adjust the configuration settings for parallel processing in the SAP system. This can include settings in transaction codes like RZ10 (for profile parameters) or RZ12 (for workload management).
  Limit Parallel Tasks: If possible, reduce the number of parallel tasks being executed simultaneously. This can help prevent overload.
  Review Background Jobs: Check the configuration and status of background jobs. Ensure that they are set up correctly and not conflicting with each other.
  Check for Locks: Use transaction codes like SM12 to check for locks in the system. If a resource is locked, you may need to resolve the locking issue.
  System Logs: Review system logs (transaction SM21) for any additional error messages or warnings that may provide more context about the issue.
  
  Related Information:
