Date parameter not displayed in Burst output

Hi,

Oracle R12.1.3

Oracle BI Publisher Desktop 11.1.1.7

Unix AIX

-------------------------------------------------------------------------

This is my data definition

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

<dataTemplate name="XXNPG_OIE_PENDING_CLAIMS" description="iExpense Pending Claims Report" Version="1.0">

  <parameters>

    <parameter name="P_DATE" dataType="character"></parameter>

  </parameters>

  <dataQuery>

    <sqlStatement name="Q1">

      <![CDATA[

and Burst report I am accessing the P_DATE which is displaying as null.

Please be advised that the expense claim(s) you submitted on or before ${P_DATE} which were sent to ${APPRV} for approval  have not yet been approved or rejected.

It is retrieving the date values in test systems but not in Live.
