• What is the cause and solution for SAP error message /IWFND/CM_COS071 - The load on backend system '&1' is too high. Try again later. ?

  The SAP error message /IWFND/CM_COS071 indicates that the load on the backend system is too high, which prevents the system from processing the request at that moment. This error is typically encountered in the context of SAP Gateway and OData services when the backend system (like an SAP ERP or S/4HANA system) is under heavy load or experiencing performance issues.
  Causes:
  
  High System Load: The backend system is processing too many requests simultaneously, leading to resource exhaustion (CPU, memory, etc.).
  Long-running Transactions: There may be long-running transactions or processes that are consuming significant resources.
  Database Locking: Database locks can cause delays in processing requests, leading to increased load.
  Network Issues: Network latency or issues can exacerbate the perception of load on the backend.
  Configuration Issues: Misconfigurations in the system or insufficient resources allocated to the backend can lead to performance bottlenecks.
  
  Solutions:
  
  Monitor System Performance: Use transaction codes like SM50 (to monitor active processes) and ST03N (to analyze workload) to identify bottlenecks.
  Check for Long-running Jobs: Use transaction SM37 to check for long-running jobs that may be consuming resources.
  Optimize Queries: If specific OData services are causing the issue, consider optimizing the underlying queries or data models.
  Increase Resources: If the backend system is consistently under heavy load, consider scaling up the resources (CPU, memory) allocated to the system.
  Load Balancing: If applicable, implement load balancing to distribute requests more evenly across multiple instances of the backend system.
  Retry Logic: Implement retry logic in the application that is making the requests to the backend, allowing it to attempt the request again after a short delay.
  Schedule Jobs During Off-Peak Hours: If possible, schedule resource-intensive jobs during off-peak hours to reduce load during peak times.
  
  Related Information:
  
  SAP Notes: Check for relevant SAP Notes that may provide additional insights or patches related to performance issues.
  System Logs: Review system logs (transaction SLG1) for any errors or warnings that may indicate underlying issues.
  Performance Tuning: Consider engaging in performance tuning activities, such as database optimization, indexing, and reviewing application code for efficiency.
  SAP Support: If the issue persists, consider reaching out to SAP Support for assistance, especially if it is impacting business operations.
  
  By addressing the underlying causes and implementing the suggested solutions, you can mitigate the occurrence of this error and improve the performance of your SAP backend system.
