- Side-by-side extensions are independent of the SAP S/4HANA version.
- Side-by-side extensions mean extension and integration with custom or standard business applications of the SAP Business Technology Platform (BTP). This is either via stable APIs or through business events from an SAP product, for example, SAP S/4HANA.
- All side-by-side extensions are technically implemented outside the core of SAP S/4HANA. As a result, remote communication between the extension and the extended app is required.
Let’s take a look at side-by-side extensibility use cases.
- S1: Custom UI on SAP Business Technology Platform
- Custom Fiori UI, built with web-based Integrated Development Environment (IDE) like SAP Business Application Studio (BAS) or SAP Web IDE, running on SAP Business Technology Platform, and with SAP predefined, released OData service.
- Use UI5 technology, UI5 templates, editors, and testing capabilities.
- Build UI applications with offline support.
- Deploy to your SAP Business Technology Platform account, or to a SAPUI5 ABAP repository.
- S2: SAP Business Technology Platform Application
- SAP Business Technology Platform application (Java, JavaScript, HANA) running on SAP Business Technology Platform with SAP predefined released OData service.
- Benefit from open standards and from a partner ecosystem that both contribute value to existing solutions and services.
- Integration scenarios (cloud Integration), benefit from SAP prepackaged integration content as reference templates to quickly realize new business scenarios.
- S3: Custom UI on SAP Business Technology Platform or SAP Business Technology Platform App with Custom OData Service
- Same as S1 and S2, but with custom OData service built with In-App extensibility tools.
- S4: New SAP Business Technology Platform Service called from SAP S/4 Extension
- SAP S/4HANA, Success Factors, and SAP C/4HANA can fire business events to call apps on SAP Business Technology Platform.
