Graphical Mapping Issue

Hi,

I follwed the blog

/people/sravya.talanki2/blog/2005/12/08/message-mapping-simplified-150-part-ii and created MM & DT as mentioned in the blog.

But when I tested the MM with the following input

<?xml version="1.0" encoding="UTF-8"?>

<ns0:MT_SRC xmlns:ns0="urn:practice:FFToXML">

<Header>

<MatNo>123</MatNo>

<MatDesc>Test Material</MatDesc>

</Header>

<item>

<Matno>123</Matno>

<Itemno>10</Itemno>

<Matgroup>A</Matgroup>

<MatType>T</MatType>

<Plant>se80</Plant>

</item>

<item>

<Matno>123</Matno>

<Itemno>20</Itemno>

<Matgroup>A</Matgroup>

<MatType>T</MatType>

<Plant>se80</Plant>

</item>

<item>

<Matno>123</Matno>

<Itemno>30</Itemno>

<Matgroup>A</Matgroup>

<MatType>T</MatType>

<Plant>se80</Plant>

</item>

</ns0:MT_SRC>

The following error had occured and no output is generated.

16:32:18 Start of test

Compilation of Mat_MM successful Cannot produce target element /ns0:MT_TRG/Header[2]/MatNo. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd Cannot produce target element /ns0:MT_TRG/Header[2]/MatNo. Check xml instance is valid for source xsd and target-field mapping fulfills requirements of target xsd
