When Ariba Supplier OnRamp receives a MIME/Multipart message containing an OrderRequest and one or more attachments, it creates an attachmentWrapper object for each attachment in the message. Ariba Supplier OnRamp collects all attachmentWrappers for a MIME message into an attachmentWrapperCollection object.

The pub.ariba.supplier.attachment folder contains services to extract and retrieve attachment content and metadata from attachmentWrapperCollection and attachmentWrapper data objects that are created by the WmAribaSupplier package.
