XML file for UWL BOR object attachment?

Dear All,

We have a workflow to approve Parked invoice. We used standard business object BUS2081.

There is a User decision step, with which users either approve or reject the document.

We have provided the document display link in that task with  BUS2081 and DISPLAY method,

which calls the MIR4 transaction to display the document.

This is working fine in SBWP.

But We are facing problems in portal.

As we need the Rejection reason, i have changed the XML file for userdecisionnote.

This part is working ok. But the attachment link is not getting displayed in the UWL.

XML file which i have coded is below.

<ItemType name="uwl.task.webflow.invoicedecision.TSXXXXXXX.SAP_WebDynpro_XSS" connector="WebFlowConnector" defaultView="DefaultView" defaultAction="viewDetail" executionMode="default">

<ItemTypeCriteria systemId="XXXXX" externalType="TSXXXXXXX" connector="WebFlowConnector"/>

<Actions>

<Action name="launchSAPAction" handler="SAPTransactionLauncher" launchInNewWindow="yes" />

<Action name="Approved" groupAction="yes" handler="UserDecisionHandler" returnToDetailViewAllowed="yes" launchInNewWindow="no">

<Properties>

<Property name="UserDecisionNote" value="true"/>

<Property name="decisionKey" value="1"/>

</Properties>

<Descriptions default="Approve"/>

</Action>

<Action name="Rejected" groupAction="yes" handler="UserDecisionHandler" returnToDetailViewAllowed="yes" launchInNewWindow="no">

<Properties>

<Property name="UserDecisionNote" value="mandatory"/>

<Property name="decisionKey" value="2"/>

</Properties>

<Descriptions default="Reject"/>

</Action>

</Actions>

</ItemType>

Is there any code need to be written to be able to get the BOR attachment  link?

Any configuration required at SWFVISU for object type BUS2081?

Pleas help.

Thanks,
