OBIEE Writeback error - The system is unable to read the Write Back Templat

Question

Hi all,
I'm trying to set up the write back feature for one of the reports. All the set up up including XML file in the custommessage folder is done.Ensured the webmessage name tag value (pmet_update) is same as the one used in the report write back template value etc.
Also the server is restarted after the latest XML file(as shown below) is copied after all type of debugging with similar threads on this matter.
But when i click on the update button in the report (button is highlighted), i'm getting the error
"The system is unable to read the Write Back Template 'pmet_update'. Please contact your system administrator."
here is the xml.
<?xml version="1.0" encoding="utf-8"?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1">
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name="pmet_update">
<XML>
<writeBack connectionPool="PMTCOG">
<insert></insert>
<update> UPDATE XREF_PMET_URL SET URL= '@{c1}' WHERE API='@{c0}'</update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
Could you please help?

Hi,
I think that you have to spacify also an SQL statement for the update tag, for example:
<?xml version="1.0" encoding="utf-8"?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1">
<WebMessageTable lang="en-us" system="WriteBack" table="Messages">
<WebMessage name="pmet_update">
<XML>
<writeBack connectionPool="PMTCOG">
<insert> select null from dual</insert>
<update> UPDATE XREF_PMET_URL SET URL= '@{c1}' WHERE API='@{c0}'</update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
The witeback wants for both the tags (<insert></insert> and <update></update>) an SQL Statement.
For me it works.
Let me know!
