Overview of Attachments

You can send attachments associated with purchase orders and invoices.

The attachments can be sent in the following methods:

• In payload: The attachment is sent as embedded binary content in the payload element of the B2B

• In message: The attachment is sent in the attachment element of the B2B message.

• MIME part: The attachment is sent as a MIME part outside of the B2B message.

The options for sending attachments depend on the delivery method and the external message type that are being used to exchange messages with the trading partner or service provider.

You can also receive attachments with inbound invoices as either embedded attachments or as MIME part for messages using the CollaborationMessageV2Service.

If the total size of the embedded attachments exceeds the Maximum Attachment Size defined in the Outbound Messaging Processing section using the Manage Collaboration Messaging Configuration task, subsequent attachments aren't processed. For purchase orders, the buyer listed in the payload receives a notification of unsent notifications.

You need to use the Manage Collaboration Messaging History task to view the total number of attachments and number of attachments processed for each message.
