Bursting XML report o/p to folder

Hi

We have a requirement where we have to burst the output to a folder

We have a xml and rtf which generates the invoice pdf and now I want to burst into a new folder

I wrote the bursting file as below

<?xml version="1.0" encoding="UTF-8"?>

<xapi:requestset xmlns:xapi="http://xmlns.oracle.com/oxp/xapi">

<xapi:request select="/EVENT/G_EVENT/ROW">

<xapi:delivery>

<xapi:filesystem id="FILE_DELIVERY" output="/tmp/Invoice_Migration/${CUST_ACCOUNT_NUMBER}.pdf"/>

</xapi:delivery>

<xapi:document output="${CUST_ACCOUNT_NUMBER}" output-type="pdf" delivery="FILE_DELIVERY">

<xapi:template type="rtf" location="xdo://XXSA.XXSA_INV_GEN.en.US?getSource=true"/>
