• What is the cause and solution for SAP error message BT858 - ALL PBT resources are used up ?

  The SAP error message BT858, which states "ALL PBT resources are used up," typically occurs in the context of SAP Business Workflow or Business Process Management (BPM). This error indicates that the system has exhausted all available resources for processing background tasks or workflow instances.
  Cause:
  
  Resource Limitation: The system has a limited number of resources (like background processing jobs or workflow instances) that can be allocated for processing. If all these resources are currently in use, new requests cannot be processed.
  Long-Running Processes: If there are long-running background jobs or workflows that are not completing, they can consume all available resources.
  Configuration Issues: Incorrect configuration of the background processing settings or workflow settings can lead to resource exhaustion.
  High Load: A sudden spike in workload or a large number of simultaneous requests can lead to resource saturation.
  
  Solution:
  
  Monitor Background Jobs: Check the status of background jobs using transaction codes like SM37 (Job Monitoring) to identify any long-running or stuck jobs. If necessary, terminate or adjust these jobs.
  Increase Resource Limits: If feasible, consider increasing the limits for background processing. This can be done in the system configuration settings.
  Optimize Workflows: Review and optimize workflows to ensure they are efficient and do not consume excessive resources. This may involve analyzing the workflow design and making adjustments.
  Check System Performance: Use transaction ST22 (Dump Analysis) and SM21 (System Log) to check for any system performance issues or errors that may be contributing to the problem.
  Schedule Jobs Appropriately: If there are scheduled jobs that run during peak hours, consider rescheduling them to off-peak times to balance the load.
  Consult SAP Notes: Check the SAP Support Portal for any relevant SAP Notes that may address this specific error or provide guidance on configuration settings.
  
  Related Information:
