SMP helps users build and deploy business- and customer-facing applications or customize existing apps, which in either case may be hosted internally or cloud-based. Developers can reach SAP's 200,000 existing customers through the company's app store.
SMP features reusable components, drag-and-drop HTML5 apps, REST APIs and reusable, customizable apps from over one hundred development partners. Like most mobile enterprise application platforms, SMP provides an cross-platform mobile development environment that allows enterprises to create an application once and run it on any mobile system.
