BizTalk flat file schema with nested nodes is giving me some trouble. What is happening is that the child record delimiter is showing up as data in the last field. I followed the recipe from this old blog post.
Managing Flat Files in BizTalk 2004
Here is the input and schema are here.
https://bitbucket.org/kirk98445/stuff/src/90becbaa638b1bc42555cf84f2a1a4cb4f3cd3fc?at=master
Result is that the xml looks fine for the most part except for the crlf in the user and ponumber fields.
<Orders xmlns="http://KS.Biztalk.EDI.Common.Amtech.ASN.FlatFileSchema1"><Header><user>USER_1234
</user></Header><Order><OrderHeader><ponumber>PO_001
</ponumber></OrderHeader><LineItems><LineItem><item>Item32 33</item></LineItem><LineItem><item>Item63 45</item></LineItem></LineItems></Order><Order><OrderHeader><ponumber>PO_002
</ponumber></OrderHeader><LineItems><LineItem><item>Item454 12</item></LineItem></LineItems></Order></Orders>
There are issues with your schema. Record "Orders" - The Child Delimiter Type property is not set for a delimited record. Record "Order" - The Child Delimiter Type property is not set for a delimited record.
Usually with this sort of flat file I would create one schema for the header, and then one for the Order & Order Lines. Then in the flat file dissembler define set the Header schema and the Document schema to the above two. This way it will de-batch you will get a message for each purchase order in the file.
But if you want it in a single schema, try this schema that uses a Sequence Group node.
