A Clean Core side-by-side extension built on SAP Business Technology Platform (BTP) — demonstrating how SAP CAP, HANA Cloud, and Build Process Automation can deliver intelligent procurement automation while maintaining full Clean Core compliance.
This solution automates Purchase Requisition (PR) suggestion and approval using:
- Forecast and inventory data from SAP HANA Cloud
- Workflow automation via SAP Build Process Automation
- A Fiori app hosted in SAP Build Work Zone
- Secure authentication through SAP Cloud Identity Services
Built to align with SAP’s Clean Core extensibility strategy, the solution illustrates how enterprises can extend SAP S/4HANA Public Cloud side-by-side without modifying the ERP core.
Clean Core architecture leveraging SAP Build, CAP, HANA Cloud, and Process Automation.
| Layer | Service / Component |
|---|---|
| Frontend | SAP Fiori / Work Zone |
| Backend | SAP CAP (Node.js) |
| Database | SAP HANA Cloud (HDI Containers) |
| Workflow | SAP Build Process Automation |
| Identity | SAP Cloud Identity Services |
| Development | SAP Business Application Studio |
| Deployment | Cloud Foundry (MTA) |
Procurement teams in SAP S/4HANA Public Cloud environments face challenges like:
