• What is the cause and solution for SAP error message PPH_MRP172 - Overall time spent in MRP Live on HANA: &1 ?

  The SAP error message PPH_MRP172, which indicates "Overall time spent in MRP Live on HANA: &1," typically relates to performance issues during the execution of the Material Requirements Planning (MRP) process in SAP S/4HANA. This message is not necessarily an error but rather a warning or informational message that indicates the time taken for the MRP run.
  Cause:
  
  
  Performance Bottlenecks: The MRP run may be taking longer than expected due to various factors such as:
  
  Large data volumes (many materials, production orders, etc.)
  Inefficient MRP settings or parameters
  Database performance issues
  Lack of proper indexing or database optimization
  High system load or resource contention
  
  
  
  Configuration Issues: Incorrect configuration of MRP parameters or settings can lead to longer processing times.
  
  
  Custom Code or Enhancements: Custom ABAP code or enhancements that are executed during the MRP run may also contribute to increased processing time.
  
  
  Solution:
  
  
  Analyze Performance: Use transaction codes like ST03N (Workload Analysis) or ST05 (SQL Trace) to analyze the performance of the MRP run. Identify any long-running queries or bottlenecks.
  
  
  Optimize MRP Settings: Review and optimize MRP parameters in the configuration. This includes:
  
  Adjusting planning horizons
  Setting appropriate lot-sizing procedures
  Reviewing the MRP type and strategy for materials
  
  
  
  Database Optimization: Ensure that the HANA database is properly optimized. This may involve:
  
  Regularly updating statistics
  Ensuring proper indexing
  Monitoring and tuning the database performance
  
  
  
  System Resources: Check the system resources (CPU, memory, I/O) during the MRP run. If the system is under heavy load, consider scheduling MRP runs during off-peak hours.
  
  
  Review Custom Code: If there are custom enhancements or user exits involved in the MRP process, review them for performance issues. Optimize or refactor any inefficient code.
  
  
  Batch Processing: If applicable, consider breaking down the MRP run into smaller batches to reduce the load on the system.
  
  
  SAP Notes and Support: Check for any relevant SAP Notes that may address performance issues related to MRP Live. You can search the SAP Support Portal for updates or patches that may improve performance.
