What are the common steps to troubleshoot performance issues in SAP system?

Common Steps to Troubleshoot Performance Issues in SAP System:

1. Identify Performance Bottlenecks: Use SAP tools like ST03, STAD, and ST05 to analyze system performance and identify areas causing bottlenecks.
2. Check Hardware Resources: Verify CPU, memory, and disk utilization using transaction ST06 to ensure the hardware resources are sufficient for optimal performance.
3. Review Workload Distribution: Use transaction ST03 to monitor workload distribution across different instances and servers to identify any imbalance causing performance issues.
4. Optimize ABAP Code: Review and optimize custom ABAP code using tools like SAT or ATC to improve performance efficiency.
5. Monitor Database Performance: Check database performance using tools like DBACockpit or ST04 to identify and rectify any issues affecting system performance.
6. Perform System Tuning: Adjust system parameters using transaction RZ11/RZ10 to fine-tune system configuration for better performance.
7. Implement SAP Notes and Patches: Stay updated with latest SAP notes and patches to resolve known performance issues and apply them to the system.
8. Consider Hardware Upgrades: If performance issues persist, consider upgrading hardware components such as CPU, memory, or disk to improve system performance.

By following these common steps and best practices, SAP BASIS administrators can effectively troubleshoot and resolve performance issues in the SAP system.
