Attribute mapping for outbound documents
If a file attached to a business document is sent from Supplier Exchange to
      the Integrated application through IDM, you must define the attributes for this document in
      Supplier Exchange. You must create a document type in Infor Document Management (with the same
      name) that you defined on the IDM Document Setup page in
      SE and add the attributes. These attributes must be same as defined for the outbound business
      document in Supplier Exchange.
    Note: The attachments sent from Supplier Exchange can only be read when these
        attributes are defined in an integrated ERP.
These files can be attached at the header or line level of the business documents. Document type must be defined in Supplier Exchange and in Infor Document Management. This enables users to search for an attachment/file in Infor Document Management.
