OBIEE Write Back

Question

Hi,
I am trying to configure write back in one of my reports. I have already created a Write back template which looks as follows:
<?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="WriteBack">
     <XML>
     <writeBack connectionPool="Connection Pool_DM">
     <insert>INSERT INTO Debt_Fact VALUES('@{c9}')</insert>
     <update>UPDATE Debt_Fact SET Remarks =('@{c9}')</update>
          <postupdate>COMMIT</postupdate>
     </writeBack>
     </XML>
     </WebMessage>
     </WebMessageTable>
</WebMessageTables>
When i try to enter values in the write back field it give me the following error:
An error occurred while writing to the server. Please check to make sure you have entered appropriate values. If the problem persists, contact your system administrator.
Odbc driver returned an error (SQLExecDirectW).

Any Help is appreciated.... Thanks

Hi Siddharth,
I came across the same while implementing the write back.
Make sure following points are checked.
1.Table whoch you are updating should disable cache
2.In Answers,user must have acess writeback previleges.For this access,you need to go manage previleges and give access.
3.Template name in Answers should match with the values in XML...i.e<WebMessage name="WriteBack">
For the error,the solution is
To ignore/fix this error, with ifnull(tablename.Remarks,'n/a') in the Fx section. Try it
