Ariba Ships Adapter for SAP NetWeaver(R); Software Enables Users of SAP(R) Solutions to Seamlessly Connect to Ariba Supplier Network



    On the heels of receiving "Powered by SAP NetWeaver(R)"
    qualification, Ariba(R), Inc. (Nasdaq:ARBA), the leading spend
    management solutions provider, today announced expanded availability
    of the Ariba Supplier Connectivity(TM) Adapter for the SAP NetWeaver
    platform. With wider shipment of the adapter, companies using
    mySAP(TM) Business Suite applications can now seamlessly connect to
    the Ariba Supplier Network(TM) solution to reduce the cost and
    simplify the process of connecting, transacting, and collaborating
    with their suppliers around the globe. The adapter is the latest in a
    series of software the company has issued to enable companies using
    ERP and other non-Ariba procurement systems to fully leverage Ariba
    Supplier Network.
    "Spend management continues to evolve, but supplier connectivity
    remains a significant challenge," said Bob Solomon, senior vice
    president, Growing Enterprise Business, Ariba. "At Ariba, we're
    focused on eliminating this barrier by allowing companies to link to
    the Ariba Supplier Network solution, regardless of the ERP procurement
    solutions they may be using. With the expanded availability of the
    Ariba Supplier Connectivity Adapter for SAP NetWeaver, we continue to
    advance this strategy."
    With more than 140,000 registered suppliers in 115 countries
    engaging in transactions worth more than $90 billion a year, Ariba
    Supplier Network is one of world's largest business transaction
    networks. Each month, participating buyers and suppliers conduct
    business with each other electronically, managing the complete
    procure-to-pay cycle -- from sourcing to orders, to invoices, and
    payment. More than 25 million purchase orders and invoices were
    carried across the network in 2005.
    According to Andrew Bartels, vice president and research analyst
    with Forrester Research, "Any company that has implemented Oracle,
    PeopleSoft, or SAP eProcurement should take a look at Ariba's supplier
    connectivity offer -- especially if they have had challenges in
    getting suppliers connected to their systems." ("Ariba Opens up Its
