Discover how new technologies such as mobile and wearable devices, combined with business-critical data, contribute to process optimization. Martin Bachmann shows how SAP Gateway enables secure connectivity of external systems and devices.
Reading this article you will learn how to:
- Add Representational State Transfer (REST) services to your system with SAP Gateway
- Create an alternative user interface based on OData
- Manage error handling supported by SAP Gateway
The introduction of an open and standardized Representational State Transfer (REST)-based communication protocol (OData) enables companies to combine various user interface technologies such as Microsoft Office or mobile devices in a secure way to SAP systems. OData — which is standardized by OASIS — is optimized for user-centric interaction and supported by various major software companies, including Microsoft, IBM, and SAP.
The supply chain process typically involves many groups of employees who contribute in various ways or roles, from power users working nearly all the time on planning to external contractors driving a truck and interacting very occasionally with the supply chain software.
These complex end-to-end processes add value only when the involved users reliably interact with the software. Especially — but definitely not only — for the more occasional users, an intuitive user interface embedded in the users’ day-to-day work environment has always been a requirement to increase acceptance and reduce training costs. This applies in particular to:
- Mobile scenarios in which the access to the SAP system has to happen via the mobile device of choice
- Users who work more in, for example, Microsoft Office or Microsoft SharePoint
- Use of state-of-the-art HTML5 technologies
