Linh,
Latest update, which may help:
I did manage to get a file to work.
Here's the basic structure of my XML (i've renamed the elements):
<?xml version="1.0" encoding="UTF-8"?>
<MyCustomBusinessObjectUploadInputRequest>
<MessageHeader>
<CreationDateTime>2014-08-11T09:48:04.000Z</CreationDateTime>
<TestDataIndicator>false</TestDataIndicator>
<ReconciliationIndicator>false</ReconciliationIndicator>
</MessageHeader>
<List listCompleteTransmissionIndicator="true" actionCode="01" reconciliationPeriodCounterValue="123">
<!---Repeat Below For Each Business Object--->
<MyCustomBusinessObject actionCode="01">
< ...Data Elements...>
</MyCustomBusinessObject>
<!---End Repeat--->
</List>
</MyCustomBusinessObjectUploadInputRequest>
Here's what i'm currently working through now - if i have a single file with this structure in Unprocessed Files, and execute the run, it does work.
However, if i upload two files and run them both at the same time, nothing happens. Both files work individually, but not together.
