Re: Does Writeback Truly Work in OBIEE 11.1.1.3.0 or 11.1.1.5.0 ?
Error:Unable to read the Writeback template
Insert--
A couple of small adjustments got your XML to work here:
<?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">
<insert> INSERT INTO FACT (PRICE,PRODUCT_KEY,REGION_KEY,SALE_UNIT,TIMEKEY,SALES_QUOTA)
values (@{c7},@{c8},@{c9},@{c10},@{c11},@{c5} ) </insert>
<update> </update>
</writeBack>
</XML>
</WebMessage>
</WebMessageTable>
</WebMessageTables>
The <writeBack> tag is written with a lower case "w".
The "connetionPool" needs an upper case "P".
Update--
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!
Award points it is useful.
Thanks,
