✅ Purpose of SIT
✔️ 1.Test interfaces with external systems.
✔️ 2.Check end-to-end process execution.
✅ Who Performs SIT
✔️ 1.SAP functional consultants.
✔️ 2.Technical consultants.
✔️ 3.Also Quality assurance (QA) teams.
✅ What Is User Acceptance Testing (UAT) in SAP-
✔️ User Acceptance Testing (UAT) validates whether the SAP system meets real business requirements and is ready for production use-
✔️ UAT focuses on business acceptance, not technical validation
✅ Purpose of UAT
✔️ Supports daily business operations
✔️ Validate reports, outputs, and workflows
✔️ Build user confidence
