Hi experts,

Do we need to do volume test in Public Cloud ERP project? Please give your comments.

Hi Eric, It is SAP's responsibility to maintain the upright performance of the system as the infrastructure as well as the system setup is taken care by SAP. Hence customers do not need to perform any stress/load test. In any case, if the customers face any issues in terms of performances/access/loads etc. then the customers can immediately log a ticket to SAP Support (component -> XX-S4C-OPR-INC). SAP should be able to assist you right away depending on the severity and impact of the issue. SAP internally has tools and automation technologies in place to continuously check the load testing on the multi-tenant cluster system and assures that the network, bandwidth, load, latency and other factors are up to the mark and are maintained as per Cloud standards.

Dear @ericyu,

In Public Cloud you usually don’t need classic infrastructure sizing trying to find the breaking point of the platform, because SAP owns the runtime and does performance testing on their side and they don’t generally publish tenant-level benchmark results but you often still should do a volume test just with a different goal, prove that your business processes, integrations, and data volumes work within your peak periods and time windows (month-end, MRP, mass jobs etc.)

Do it if you have any of these risk factors:

• High transactional volumes (orders, deliveries, invoices, warehouse postings, journal entries, etc.)
• Tight batch windows (jobs, MRP, settlement, dunning, EOM close)
• Many/critical integrations (BTP, EDI, external tax, banks, e-commerce) where throughput/queues matter
• Significant data migration volume and you need confidence that reporting and processing times stay acceptable
• Custom extensions / custom analytics

• Business peak simulation run the top 10–20 critical processes at expected peak
• Integration throughput test burst messages at realistic peak rates and validate queues, retries, end-to-end completion times
• Period-end rehearsal close steps that must finish in a window (FI close tasks, MRP runs, etc.).
• Data-volume realism test with production-like master/transaction data

To get production like data in your Quality system, SAP offers Test Data Refresh copying master and transactional data from Production to Quality, configuration isn’t copied and integrations must be validated afterward

More details below:

How to execute it safely:

1. Monitor and document issues, use an ALM/monitoring layer SAP Cloud ALM is designed to help monitor the landscape, including extensions
2. Prepare realistic data migration rehearsal loads or Test Data Refresh
3. Run focused scenarios, measure response times + end-to-end completion including interfaces
