SAP Fiori & UI5 Development Services
SAP Fiori is SAP's design system and SAPUI5 is the JavaScript framework behind it. Appsierra's UI5 engineers build the screens your users actually touch — metadata-driven Fiori elements apps, freestyle UI5 where a journey needs it, and the Launchpad or Build Work Zone they live in — on clean OData and CDS backends, responsive and accessible, so people adopt SAP instead of avoiding it.
An ERP is only as good as the screens people use, and the classic SAP GUI is where adoption goes to die. SAP Fiori is the answer — a role-based, responsive, task-focused experience — and SAPUI5 is how it is built. Appsierra's UI5 engineers deliver that front end properly: Fiori elements apps generated from OData and CDS annotations where the pattern fits, freestyle UI5 where a journey genuinely needs custom controls, and a Launchpad that gives each role a coherent set of apps.
We treat the front end as engineering, not decoration: apps are built to the current Horizon theme, made responsive and accessible, and backed by clean OData V2/V4 services. The front end is only half the app — the business logic and services behind a Fiori screen are ABAP, RAP and CDS work, and our QA practice proves the whole app end to end rather than eyeballing the UI.
What the pod delivers
Fiori elements apps
List report, object page, analytical list page, overview page and worklist apps generated from OData/CDS annotations — standard SAP UX, minimal custom code, fast to deliver and upgrade-safe.
Freestyle UI5 apps
Custom SAPUI5 apps with XML views, MVC and bespoke controls for journeys the metadata-driven patterns can't express, written to SAP's own coding and performance guidelines.
OData & CDS backends
Clean OData V2/V4 services over CDS views, so the data and annotations that drive the UI are performant and reusable rather than hand-rolled per screen.
Launchpad & Work Zone
SAP Fiori Launchpad and SAP Build Work Zone configured with role-based catalogs and groups, so each user gets a coherent set of apps rather than a wall of tiles.
How the engagement runs
Four steps from first call to a pod that is measurably working. You are never more than two weeks from evidence.
The stack we work in
We adopt your tools rather than imposing ours. These are the ones our engineers are already senior in.
What our SAP Fiori & UI5 engineers build
The SAP front end — standard patterns where they fit, custom where the journey needs it.
Fiori elements
Metadata-driven apps built from CDS annotations — list reports, object pages, analytical and overview pages — so you get standard, maintainable UX with the least custom code.
Freestyle UI5
Hand-built SAPUI5 apps with XML views, controllers and custom controls for approval journeys, wizards and dashboards that the standard floorplans cannot express.
Responsive & adaptive
Apps that work from desktop to tablet to phone, so field and shop-floor users get a usable SAP experience rather than a desktop screen squeezed onto a device.
Theming & branding
Apps built to the current SAP Horizon theme and tuned in the UI Theme Designer where you need your own branding, so the estate looks like one product.
Accessibility
Keyboard, screen-reader and contrast support built into the apps, so your SAP front end meets the accessibility bar your organisation and your users require.
Launchpad experience
Fiori Launchpad and SAP Build Work Zone set up with role-based catalogs, groups and spaces, so the entry point to SAP is coherent per role, not a tile dump.
How we deliver the SAP front end
Standard-first, on clean backends, tested like software.
Fiori elements first
We reach for metadata-driven Fiori elements before freestyle, because the pattern that writes the least custom code is the one that stays maintainable and upgrade-safe.
Front and back together
The UI5 engineers work with the ABAP/CDS engineers behind the OData service, so the annotations, the data and the screen are built as one app rather than thrown over a wall.
Tested end to end
Apps are tested across the devices and browsers your users have, with automated UI tests where it pays, because a Fiori app that renders is not the same as one that posts the right document.
Documented and handed over
Apps, their OData services and the Launchpad configuration are documented and transferred, so your team can extend the front end without depending on us.
Why leaders choose Appsierra for SAP Fiori & UI5
Adoption is the goal
We build the screens that get SAP used — role-based, responsive, fast — because a rollout only pays back when people choose the system over the workaround.
Standard where it counts
Fiori elements first keeps custom code low and upgrade risk lower, so your front end is an asset rather than a maintenance burden.
Full-stack SAP, one pod
The same pod owns the UI5 front end, the OData/CDS/ABAP backend and the QA, so the app works end to end rather than looking right and posting wrong.
