Elements: How Do You Freestyle for: Dashboards, guided wizards, canvas-style tools and highly branded 2
experiences.
Choose?
Hybrid approach: Embed custom UI5 views and fragments inside Fiori elements

through extension points.
Total cost: Freestyle needs more code, testing and upgrade work; Fiori elements shifts 
Q U I C K  A N S W E R 4 much of that effort to SAP.
Default to Fiori elements; go freestyle only 
when floorplans and extensions cannot express 
the interaction. Governance: Review custom screens against the SAP Fiori design guidelines to keep 5
UX consistent.
Rule of thumb: If most screens need heavy custom code, revisit the process design or

CAP vs RAP: Which 
Backend Should You RAP: ABAP RESTful Application Programming Model uses CDS view entities and 2
behavior definitions for transactional services.
Choose?
Fiori elements fit: Both expose annotated OData V4 services that Fiori elements

consumes with little UI code.
Team skills: Pick the model your team already knows; both are recommended by SAP 
Q U I C K  A N S W E R 4 for new development.
Choose CAP for Node.js or Java teams on BTP, 
and RAP for ABAP teams on S/4HANA or ABAP 
Cloud. Data location: RAP suits logic close to S/4HANA data; CAP suits cross-system apps and 5
new data models on BTP.
6 ABAP Cloud: RAP on ABAP Cloud uses released APIs, so extensions stay clean-core.
