Web Services powered by XML and three other core

technologies: WSDL, SOAP, and UDDI

Helping our Clients Achieve Procurement Excellence.

What are Web services?

Web services are software components that communicate using standards-based Web

technologies including HTTP and XML-based messaging. Web services are designed to be

accessed by other applications. Since they are based on open standards such as HTTP and

XML-based protocols including SOAP and WSDL, Web services are hardware,

programming language, and operating system independent.

Web services are powered by XML and three other core technologies: WSDL, SOAP, and

UDDI

(Simple Object

Access Protocol)

XML is a W3C (World Wide Web Consortium) specification that defines a meta-languagefor describing data. In XML applications, data is described by surrounding it withcustomizable, text-based tags that give information about the data itself as well as itshierarchical structure

WSDL is an XML-based format for describing Web services. Clients wishing toaccess a Web service can read and interpret its WSDL file to learn about thelocation of the service and its available operations

Six main elements of WSDL file. · Port type - Describes operations performed by the service. · Port - Specifies an address for a binding i.e. communication port · Message - Describes name & format of the message · Types - Defines data types used by the service for sending messages · Binding - Defines communication protocol · Service - Specifies the address for accessing the service

SOAP is an XML-based protocol from the W3C for exchanging data over HTTP. It

provides a simple, standards-based method for sending XML messages between

applications. Web services use SOAP to send messages between a service and its

client(s)

Some of the elements of SOAP documents are:

· Envelope - Specifies that the XML document is a SOAP message

· Header (Optional) - contains information relevant to the message, e.g. the date the

message was sent, authentication data, etc

· Body - Includes the message payload

· Fault (optional)- carries information about a client or server error within a SOAP

message

Inbound end points are used when the task is initiated by the ERP system.

Outbound end points are used when the task is initiated by the SAP Ariba system

SAP Ariba SOAP web service APIs enable you to exchange data between SAP Ariba Strategic

Sourcing solutions and other systems, such as ERP systems, for real-time data integration. You

can use the SOAP Web Service APIs to extend and integrate SAP Ariba solution to meet your

unique domain specific needs.

SAP Ariba SOAP web services include integration tasks that send and receive SOAP messages

for web services. An integration task requires an end point for the logical communication

channel used by the web service. An end point consists of the URL and authentication

information that controls access to the end point.

There are two types of end points:
