Key Challenges
• Script creation and customization is high involving GUI/Web/Portal/Mobile
scenarios
• Handling run time issues in test scripts related to test data/configuration/locks
✓ User activity through SAP GUI/SAP web/Fiori/Mobile
✓ Workload Design can be done using T-codes
✓ Single user and multi user test executions
Solutions
Select the right performance testing tool to test
Leverage Functional Automation scripts – e.g Worksoft + Neotys

Key Challenges
• Test Data for existing and new business scenarios
• Test Data from external source system to SAP (xmls / flat files)
• Test Data for Day in the life scenario
Solutions
Frequent DB refresh from production and extraction of right data sets from existing
SAP systems
Custom Approach with Snapshot/Restore for a repeated and faster Execution
Cycles.
Limited with CPU/Memory/Diskk
and often leads to I/O bottleneck
and causes performance issues
Multi core CPU, parallel processing,
Data compression and partitioning -
In-Memory computing gives good
performance

8. Factors for Performance Assurance
Planning
Detail Project Plan, Coordination mechanism,
Workshops for Workload, PT Methodology,
Triaging meetings
WorkLoad Design
Analyze through Tcodes and Tables
from SAP and all other existing
systems for a detailed and Day-in-life
Workload
Batch Strategy
Batches occupies 80% of the
Production load. Critical, Frequent
Batches to be scoped and execution
planned as per production schedules
Data Modeling
Develope Custom Approach with
Snapshot/Restore for a repeated and
faster Execution Cycles.
Tuning
Engineering and Tuning Strategy by
analyzing the integrated system config and
tracing the poorly performing scenarios
Monitoring
Live Monitoring of all layers of SAP by
leveraging Native T-codes,
monitoring tools, DB Reports
Integrated Execution
Integrated Production like Testing -
Online, Batches, Interfaces, RFGuns,
external calls
