I am using below code to update list value in agile PLM.

<soapenv:Body>

    <updateObject>

        <request>

        <requests>

                <classIdentifier>Assembly</classIdentifier>

                <objectNumber>P00125</objectNumber>

                <data rowId="0">

                <itemCategory xsi:type="AgileListEntryType" attributeId="1082">

                <selection>

                    <id/>

                    <apiName/>

                    <value>Device</value>

                </selection>

               </itemCategory>

               </data>

      </requests>

      </request>

    </updateObject>
