The WebService Designer is a component of ERPConnect Services which allows you to connect your SharePoint applications to SAP using standard web service protocols. With the built-in graphical designer, a power user or solution architect is able to design and deploy a web service providing read/write access to SAP, without the need to write any code. The design of the web service is simplified for the user through a graphical editor for modeling a process flow and connecting individual process steps to the SAP objects of your choice. A wide range from simple to complex business scenarios can be supported with the WebService Designer. Typical consumer applications are forms applications (including Nintex Forms), workflow applications, or custom SharePoint applications that require access to SAP business data.
