Hi,

I am trying to create report from scratch and add a dataprovider based on universe with query filter.  Can you please guide me to acheive this.  I am on 4.1.

I thought to create a new discussion for this, as I didn't find specific material online.

I was trying to create a new webi report with a data provider based on a universe.

So, I create a document, then added a data provider and try to put on specification with :

URL : biprws/raylight/v1/documents/9486/dataproviders/DP1/specification

And getting error :

<error>

<error_code>

WSR 00102

</error_code>

<message>

Illegal argument ("while trying to invoke the method com.sap.sl.queryspec.QuerySpec.getQueries() of a null object loaded from local variable 'querySpec'")

</message>

</error>

Payload :

<queryspec:QuerySpec dataProviderId="DP1">

<queryParameters>

<duplicatedRowsProperty activated="true" value="true" />

<maxRetrievalTimeInSecondsProperty value="300" />

<maxRowsRetrievedProperty value="90000" />

<removeEmptyRowsProperty activated="true" value="true" />

<allowOtherUserToEditQueryProperty activated="true" value="true" />

<resetContextOnRefreshProperty activated="true" value="true" />

<stripQueryProperty />

<useBexQueryDefaultValue activated="true" value="true" />

</queryParameters>

<queriesTree xsi:type="queryspec:QueryOperatorNode" queryOperator="Union">

<children xsi:type="queryspec:QueryDataNode">

<bOQuery name="Query" identifier="_Y_xTkEqsEea-vo0a6XgtoA">

<resultObjects identifier="DS0.DObc" name="Year" />

<resultObjects identifier="DS0.DOb9" name="Month" />

<conditionPart />

</bOQuery>

</children>

</queriesTree>

<propertyBag key="DUPLICATED_ROWS_UNDEFINED_VALUE" value="-1" />

<propertyBag key="RESET_CONTEXT_ON_REFRESH_UNDEFINED_VALUE" value="-1" />

<propertyBag key="ALLOW_THE_USER_TO_EDIT_QUERY_UNDEFINED_VALUE" value="-1" />

</queryspec:QuerySpec>

I am badly stuck there. and not able to identify how to generate

<bOQuery name="Query" identifier="_Y_xTkEqsEea-vo0a6XgtoA">

I am successfully able to create report manually on the same universe. But using restful I am not able to understand how A data provider is mapped with a query specification (as it doesn't contain any SQL). Does it create an inbuild SQL ?

I copied the above payload by doing a get from an manually created webi report/data provider. I understand - <bOQuery name="Query" identifier="_Y_xTkEqsEea-vo0a6XgtoA"> should be a system generated. But when I remove it. it gives me the same error as well.

The Data provider I created is as followed :

<dataprovider>

<id>DP1</id>

<name>Query 2</name>

<dataSourceId>5291</dataSourceId>

<dataSourcePrefix>DS0</dataSourcePrefix>

<dataSourceType>unv</dataSourceType>

<duration>0</duration>

<isPartial>false</isPartial>

<rowCount>0</rowCount>

</dataprovider>

Please suggest.
