Parameters in Data Templates

Question

Hey gurus!
I am using 10.1.3.3.3 and am having a problem with parameters. If I just use a sql query for my data model and create a parameter, it works fine. I am having a problem when I use a data template in my data model and try and use a parameter.
The beginning of my data template is this:
<dataTemplate dataSourceRef="oltpdev" name="mdd_rmv_stuff" defaultPackage="mdd_rmv_stuff">
<properties>
<property name="xml_tag_case" value="upper"/>
</properties>
<parameters>
<parameter name="p_manager_product_id" dataType="integer"/>
</parameters>
<lexicals>
</lexicals>
<dataQuery>
<sqlStatement name="Q_MAIN">
select mp.manager_product_id mp_id,
mp.manager_product_name,
mp.manager_roof_id
from manager_product mp
where mp.manager_product_id=:p_manager_product_id
</sqlStatement>
You can see where I am trying to use the parameter. I get this error when I try to view the report:
====================================================================
Error
The report cannot be rendered because of an error, please contact the administrator.
Error Detail
ORA-06550: line 2, column 1:
PLS-00201: identifier 'MDD_RMV_STUFF.P_MANAGER_PRODUCT_ID' must be declared
ORA-06550: line 2, column 1:
PL/SQL: Statement ignored
====================================================================
Any help would be appreciated!!!

If you don't own any data triggers and you don't need to push parameters to PL/SQL then don't define defaultPackage attribute, parameters will bind to the Queries and we will not push to PL/SQL
<?xml version="1.0" encoding="WINDOWS-1252" ?>
*<dataTemplate name="dataTemplateName" description="Template description" version="1.0">*
<parameters>
<parameter name="p_DEPTNO" dataType="Number" defaultValue="20"/>
</parameters>
<dataQuery>
<sqlStatement name="Q1">
<![CDATA[SELECT DEPTNO DEPTNO1,DNAME,LOC from dept
                     order by deptno]]>
</sqlStatement>
<sqlStatement name="Q2">
<![CDATA[SELECT  EMPNO,ENAME,JOB,MGR,HIREDATE,SAL,nvl(COMM,0) COMM
                     from EMP
                     WHERE DEPTNO = :DEPTNO1 ]]>
</sqlStatement>
</dataQuery>
<dataStructure>
<group name="G_DEPT" source="Q1">
<element name="DEPT_NUMBER" value="DEPTNO1" />
<element name="DEPT_NAME" value="DNAME"/>
<element name="DEPTSAL" value="G_EMP.SALARY" function="SUM()"/>
<element name="LOCATION" value="LOC" />
<group name="G_EMP" source="Q2">
<element name="EMPLOYEE_NUMBER" value="EMPNO" />
<element name="NAME" value="ENAME"/>
<element name="JOB" value="JOB" />
<element name="MANAGER" value="MGR"/>
<element name= "HIREDATE" value="HIREDATE"/>
<element name="SALARY" value="SAL"/>
</group>     
</group>
</dataStructure>
</dataTemplate>
