Write-back problem in OBI SE1

Question

Hi,
I am trying to use write-back functionality , but I keep getting an error.
- For this template
<?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="updatePO">
<XML>
<writeBack connectionPool="agip">
<insert> </insert>
<update>UPDATE dim_purchase_order SET Sole_Source='@{c4}' WHERE Procurement_id=@{c0}
</update>
<postUpdate> COMMIT </postUpdate>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
I am receiving this error:
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
State: HY000. Code: 10058. [NQODBC] [SQL_STATE: HY000] [nQSError: 10058] A general error has occurred. [nQSError: 43093] An error occurred while processing the EXECUTE PHYSICAL statement. [nQSError: 16001] ODBC error state: S1000 code: 1456 message: [Oracle][ODBC][Ora]ORA-01456: may not perform insert/delete/update operation inside a READ ONLY transaction. [nQSError: 16015] SQL statement execution failed. (HY000)
SQL Issued: EXECUTE PHYSICAL CONNECTION POOL agip UPDATE dim_purchase_order SET Sole_Source='Yes' WHERE Procurement_id=542
Please help, I need to clarify if it is possible to use write-back in obi se1.
Many thanks,

Here is an example of xml that works for me
The main difference that I can see, is that I don't use the tag "<postUpdate> COMMIT </postUpdate>"
<?xml version="1.0" encoding="utf-8" ?>
<WebMessageTables xmlns:sawm="com.siebel.analytics.web/message/v1">
<WebMessageTable lang="en-us" system="WriteBack" table="INDICATORI_LUNA">
<WebMessage name="Salarii_Angajati_Writeback">
<XML>
<writeBack connectionPool="WriteBack">
<insert>insert into INDICATORI_LUNA (AN_LUNA, SALARII, NUMAR_ANGAJATI)values(@{c0}, @{c2}, @{c1})</insert>
<update>update INDICATORI_LUNA set SALARII=@{c2}, NUMAR_ANGAJATI=@{c1} where AN_LUNA=@{c0}</update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
I hope that works.
Best regards
