CAUSE
This problem occurs because for some EDI schemas, the generated XML output may have missing information or incorrect information in the loop structures for those schemas.
For example, you have the following data to be validated against the D97B PRICAT (Price/Sales Catalog) schema:
LIN+1'PIA+5+F2N028EA06:VP::91+F2N028EA06:MF'
In this scenario, BizTalk Server generates the following incorrect XML output:
<LINLoop1>
<PIA PIA01="5">
<C212_2 C21201="F2N028EA06" C21202="MF" C21204="91"/>
</PIA>
You expect BizTalk Server to generate the following correct XML output:
<LINLoop1>
<PIA PIA01="5">
<C212_x C21201="F2N028EA06" C21202="VP" C21204="91"/>
<C212_x C21201="F2N028EA06" C21202="MF"/>
</PIA>
