This performance attribute displays the average usage of all background
work processes, by default averaged over the last hour.

System Response

If an alert is generated in this node, the start of the background job
can be delayed, as it may not be possible to assign jobs whose start
condition is fulfilled to a free work process immediately. When

• What is the cause and solution for SAP error message RT626 - Percentage of currently used background processing capacity ?

  The SAP error message RT626 indicates that the percentage of currently used background processing capacity has reached a critical level. This typically means that the system is experiencing high demand for background processing jobs, which can lead to performance issues or delays in job execution.
  Cause:
  
  High Volume of Background Jobs: There may be too many background jobs scheduled or running simultaneously, consuming the available processing capacity.
  Insufficient System Resources: The system may not have enough CPU or memory resources allocated to handle the current load of background jobs.
  Configuration Issues: The background processing configuration may not be optimized for the current workload.
  Long-Running Jobs: Some jobs may be taking longer than expected to complete, leading to a backlog of jobs waiting to be processed.
  
  Solution:
  
  Monitor Background Jobs: Use transaction codes like SM37 to monitor the status of background jobs. Identify any long-running or failed jobs that may need attention.
  Optimize Job Scheduling: Review the scheduling of background jobs. If possible, stagger the execution times of jobs to reduce peak load.
  Increase System Resources: If the system is consistently reaching capacity, consider increasing the hardware resources (CPU, memory) allocated to the SAP system.
  Adjust Background Processing Parameters: Check and adjust the background processing parameters in the SAP system. This can be done in transaction RZ10 or RZ11 to modify profile parameters related to background processing.
  Review Job Priorities: Ensure that critical jobs have higher priority settings, allowing them to execute before less critical jobs.
  Clean Up Old Jobs: Regularly clean up old or unnecessary background jobs to free up resources.
