If you have a payload save it to a file.
In TN go to Doc Types
Run this document through and see if it finds a document type
If no document type is found you will have to create one.
Once you have created the document type you should create a processing rule.
Your WmEDIINT was working fine.
It could NOT identify the document or a processing rule.
I do NOT KNOW why it did not show up in TN as unknown Xs three.
Hope this helps
