Deploy SAP Access Anywhere — Without New Infrastructure
With 60% of S/4HANA projects exceeding budget (Horvath 2025) and SAP licensing costs rising 45% (Gartner), the last thing your IT team needs is more infrastructure to manage. Liquid UI gives you three proven deployment options — server, desktop, or mobile — all using the same Native Channel Architecture. Zero middleware. Zero Fiori. One platform.
Three Deployment Options — Zero Middleware in All of Them
Server Deployment
Centralized management for your entire organization. Deploy Liquid UI Server on-premises or in your cloud — one server handles scripts, licensing, and configuration for every connected user and device. With SAP licensing costs rising 45% (E3 Magazine / Gartner) (Gartner), centralizing license management through one platform delivers immediate TCO savings.
Desktop In-Process
Runs directly inside SAP GUI on Windows 10 and 11. Zero infrastructure required — activate with a single click. Ideal for developer workstations, pilots, and organizations that want to start transforming SAP screens immediately — without a procurement cycle or server provisioning.
Mobile Deployment
Native apps for iOS and Android connect through Liquid UI Server to your SAP system. Full MDM support for enterprise fleet management. The enterprise MDM market is projected to reach $105B by 2034 (Fortune Business Insights) — Liquid UI integrates with the platforms you already use (Intune, VMware, MobileIron) instead of adding another layer.
Server Deployment — Centralized Control, Enterprise Scale
Liquid UI Server is a patented gateway that sits between your SAP systems and every client — desktop, mobile, web, and scangun. It uses SAP's native DIAG protocol to consolidate DYNPRO screens and transactions, optimizing traffic across your network while centralizing all customization scripts and licenses in one place.
Why IT teams choose Server deployment
- Single point of management — update scripts once, every user gets the change instantly. No desktop-by-desktop rollouts.
- Multi-system connectivity — connect up to 4 SAP instances (ECC, S/4HANA, BW, etc.) from one server.
- Cloud or on-premises — deploy on physical servers, VMs, or any cloud (AWS, Azure, GCP). With 32% of organizations already on S/4HANA (SAPinsider) and 27% in active implementation, Liquid UI Server supports every deployment scenario — on-premise, private cloud, or hybrid.
- Enterprise-grade security — TLS 1.3 encryption, SAPCRYPTO support, mutual client certificates, Kerberos/AD single sign-on.
- License optimization — centralized license management through LAMP gives you real-time usage visibility. Critical when SAP private cloud renewals are increasing 10%+ annually (The Register) (The Register, citing Gartner).
Average 52% Throughput Improvement
Liquid UI Server's NCA traffic optimization consolidates multiple DYNPRO screen round-trips into single network exchanges. The result: dramatic performance gains on every SAP transaction, especially over remote and mobile connections.
SAP recommends latency under 200ms for front-end user access, and Citrix classifies anything above 300ms as "Poor" (eG Innovations). When your users are on warehouse Wi-Fi, field 4G/5G, or working remotely, latency is your enemy. NCA compression reduces what the network needs to carry — turning poor connections into usable ones.
Measured results across SAP transactions
| Transaction | Module | Improvement |
|---|---|---|
| MB0A | MM — Goods Receipt | 73.7% |
| IW32 | PM — Change Order | 70.3% |
| IW31 | PM — Create Order | 69.3% |
| ME22 | MM — Change PO | 67.5% |
| IH02 | PM — Equipment | 58.2% |
| IW22 | PM — Change Notification | 53.0% |
| VA01 | SD — Create Order | 41.2% |
| VA03 | SD — Display Order | 23.5% |
Average improvement: 52% across all measured transactions.
End-to-End TLS 1.3 Encryption
Every connection between client and SAP — whether over 5G, LTE, WiFi, or wired Ethernet — is encrypted end-to-end using TLS 1.3. The Liquid UI Server's multi-threaded architecture handles encryption at the server level, so individual devices don't need VPN tunnels or separate security infrastructure.
Security architecture
- TLS 1.3 standard — the latest transport security protocol, encrypting all DIAG traffic between clients and the server.
- Client certificate support — mutual TLS authentication ensures only authorized devices connect to your SAP systems.
- No data at rest on devices — all data stays in SAP. Mobile and desktop clients are display-only — nothing is cached or stored locally.
- Native SAP authentication — users log in with their existing SAP credentials. No separate identity provider required (though SSO is supported).
- Centralized audit trail — all transactions flow through the server, giving you a single point for logging, monitoring, and compliance.
System requirements
- OS: Windows Server 2016, 2019, or 2022 (physical host or VM)
- CPU: 1.4 GHz 64-bit or faster (single-core) / 1.3 GHz (dual-core)
- RAM: 512 MB minimum, 2–8 GB recommended
- Disk: 32 GB
- Browser: Edge 106+, Chrome 106+, or Firefox 3.0+
- SAP GUI: 3.0 or above
Desktop In-Process — Runs Inside SAP GUI, Nothing Else Needed
Liquid UI WS runs as a Windows service directly inside SAP GUI — no server, no middleware, no infrastructure. It loads as part of your existing SAP GUI installation on Windows 10 and 11, activates with a single click (Alt+F12), and starts transforming screens immediately.
Why IT teams choose Desktop deployment
- Zero infrastructure — installs into your existing SAP GUI directory. No servers, no ports, no firewall rules. No procurement cycle.
- Instant activation — one click in SAP GUI to enable. Users can start using simplified screens in minutes, not weeks.
- Perfect for pilots — prove the value on a few desktops before committing to a full server rollout. With 70% of ERP rollouts falling short of expectations (McKinsey via Access.dev) (McKinsey), a zero-risk pilot that shows results in days — not months — changes the conversation.
- Flexible script hosting — store scripts locally, on a network share, via HTTP/FTP, or in SAP Web Repository. Graduate to Liquid UI Server when you're ready to scale.
- S/4HANA ready — the same scripts work on ECC and S/4HANA. Your pilot investment carries forward.
Mobile Deployment — Real SAP on Any Device, Anywhere
Native Liquid UI apps for iOS and Android connect through Liquid UI Server directly to your SAP system. No Fiori rebuild, no middleware — your existing transactions and Z-codes work on mobile immediately. Field workers get the same data integrity and transaction richness as desktop SAP GUI users.
Why IT teams choose Mobile deployment
- Native apps — real iOS and Android apps (App Store & Google Play), not browser wrappers. Fast, responsive, and built for touch.
- Full MDM support — compatible with all major Mobile Device Management platforms (MobileIron, Intune, VMware Workspace ONE). The enterprise MDM market ($15.75B in 2025) (Fortune Business Insights) reflects how seriously organizations take device governance — Liquid UI works with your existing investment. Contact rfi@guixt.com for MDM integration guidance specific to your platform.
- Offline capability — cache transactions for warehouse and field scenarios. Sync when connectivity returns.
- No Fiori licensing overhead — unlike premium Fiori apps at ~$150/user (2-data.com) with 22% annual maintenance, Liquid UI provides full SAP mobile access through a single platform license. For 1,000 mobile users, that difference alone can save over $150,000 per year.
- IoT integration — barcode scanners, GPS, camera, voice — all accessible via JavaScript scripting.
Script Hosting Options — Where Do Your Customizations Live?
Local Drive
Store scripts on each user's local drive (e.g., C:\guixt\scripts). Simplest setup — ideal for developers and pilots. Each user has full control over their scripts.
Best for: Development, prototyping, single-user testing
Network Share
Host scripts on a central file server (e.g., \\Server\GuiXT\scripts). All users read from the same location — update once, everyone gets the change. Supports Windows File Replication to reduce WAN traffic.
Best for: Teams of 10–100 users, organizations with existing file server infrastructure
Web / FTP Server
Serve scripts via HTTP or FTP (e.g., http://intranet.company.com/guixt/scripts). Access across your entire network with standard web protocols. Central management with familiar web server tools.
Best for: Geographically distributed organizations, multi-site deployments
SAP Web Repository
Store scripts inside SAP itself using SAP Web Repository (SAPWR). Leverages SAP's own transport and correction system for change management. Automatic local caching eliminates repeated downloads.
Best for: Organizations with strict SAP change management requirements, heavily regulated industries
Liquid UI Server
Scripts hosted directly on the Liquid UI Server. The server manages scripts for all connected clients — desktop and mobile. Simplest option for mobile deployments since mobile devices always connect through the server anyway.
Best for: Mobile deployments, large-scale rollouts, organizations that want one management point for everything
Which Deployment Is Right for You?
| Desktop (In-Process) | Server | Mobile | |
|---|---|---|---|
| Infrastructure | None — runs in SAP GUI | Windows Server (cloud or on-prem) | Server + native app |
| Best for | Pilots, developers, small teams | Enterprise rollout, central management | Field workers, warehouse, plant floor |
| Script management | Local, network, or SAP Web Repo | Centralized on server | Centralized on server |
| SAP systems | 1 per session | Up to 4 simultaneous | Via server |
| OS | Windows 10 / 11 | Windows Server 2016–2022 | iOS 14+ / Android 9+ |
| Typical time to deploy | Minutes (single click) | Days (install + configure) | Weeks (server + MDM + rollout) |
| vs. Fiori alternative | No equivalent | Fiori requires BTP + Gateway + per-app licensing (2-data.com) | Fiori mobile apps take months to build (Neptune Software) |
All three options use the same Native Channel Architecture, the same JavaScript scripting language, and the same customizations. Start with Desktop, graduate to Server, extend to Mobile — your scripts carry forward at every stage.
