• What is the cause and solution for SAP error message WEBDYNPRO_RT013 - CPU time of called sessions ?

  The SAP error message WEBDYNPRO_RT013: CPU time of called sessions typically indicates that the Web Dynpro application or its called sessions have exceeded the allowed CPU time limit during execution. This is a runtime error related to performance and resource consumption.
  
  Cause
  
  Excessive CPU usage: The Web Dynpro application or one of its called sessions is consuming more CPU time than the system threshold allows.
  Long-running processes: The application might be performing complex calculations, large data processing, or inefficient loops.
  Infinite loops or inefficient code: Programming errors causing loops or recursive calls that never terminate or take too long.
  Heavy database operations: Slow or unoptimized database queries triggered by the Web Dynpro application.
  System resource limits: The SAP system or Web Dynpro runtime environment has CPU time limits configured to prevent runaway processes.
  
  
  Solution
  
  
  Analyze the application code:
  
  Check for inefficient loops, recursive calls, or heavy computations.
  Optimize algorithms and logic to reduce CPU consumption.
  Use performance analysis tools (e.g., ST12, SAT) to identify hotspots.
  
  
  
  Optimize database access:
  
  Review and optimize SQL queries.
  Use proper indexes and avoid unnecessary data retrieval.
  Consider buffering or caching data if applicable.
  
  
  
  Check Web Dynpro configuration:
  
  Review the timeout and CPU time limits configured in the system.
  Adjust parameters if necessary, but only after ensuring the application is optimized.
  
  
  
  Use SAP transaction ST22 and SM50/SM66:
  
  Check for dumps related to this error.
  Monitor active processes and CPU usage.
  
  
  
  Divide workload:
  
  If possible, split large processing tasks into smaller chunks.
  Use background jobs or asynchronous processing for heavy tasks.
