Many to One Mapping issue

Question

Hi Experts,
I am currently facing issue with many to one mapping . I have a source schema called revenue having Profit and Profit GST which is looping multiple times. I need to copy the name,value and GST value for each type into the destination schema.
i am using Looping funtiod to create item profit records and than copying name and value from source to destination but the problem statement is that i am unable to map the GST value
Thanks
Abhishek

Answer 1

could you post the schema definition please
well why i am asking is, in General matching the records will be based on common node values in corresponding records.
Assume you have 2 records of Profit and 2 records of ProfitGST in the source message like below, you cannot match the records unless you have some value common in both the records. i mean there should be some common node or attribute value that exits in
both records.
assume the following sample with 2 records each
<ns0:Revenue xmlns:ns0="http://TestSample">
<ns0:profit availabilityIncentivePayment="342" increasedCapacityCharge ="121" increasedCapacaityPayment="231" />
<ns0:profit availabilityIncentivePayment="100" increasedCapacityCharge ="110" increasedCapacaityPayment="120" />
<ns0:profitGST availabilityIncentivePayment="55" increasedCapacityCharge ="21" increasedCapacaityPayment="23"/>
<ns0:profitGST availabilityIncentivePayment="150" increasedCapacityCharge ="160" increasedCapacaityPayment="170"/>
</ns0:Revenue>
if you observe the above sample instance, it does have 2 records each, but Profit record's nodes values
are no where common with ProftGST record's node values.
And for every Profit record, you want to pick corresponding GST value from ProfitGST record. However, since you don't have atleast one common node/attribute value here, you will not find a way to relate corresponding records. Means while mapping the first
record of Profit, it cannot decide which record's nodes values in the ProftGST should pick to match as there are 2 records of ProfitGSt and with no relation with Profit Records.
if the requirement is such that the records should be matched by the order(index) irrespective
or the values in them, then that can be achieved easily with postion() function in the for loop.  just try to use code some thing like below sample xslt script like below, apply the proper name spaces and put full names as applicable in your scirpt, mould
it as per your need
<ns0:Root>
<xsl:for-each select="Profit">
<Profit>
<xsl:if test="@availabilityIncentivePayment">
<name>
name>availabilityIncentivePayment</name>
</name>
</xsl:if>
<xsl:if test="@increasedCapacityCharge">
<Value>
<xsl:value-of select="@increasedCapacityCharge" />
</Value>
</xsl:if>
<xsl:if test="../profitGST/@availabilityIncentivePayment">
<ProfitGSt>
<xsl:value-of select="../profitGST/@availabilityIncentivePayment[position()]" />
</ProfitGSt>
</xsl:if>
</Profit>
</xsl:for-each>
</ns0:Root>
