By default B2Bi sends payloads as attachment in an email message. The payload can be sent as inline body if needed by setting the attribute
PayloadLocation with a value 'body'.

Allowed values are "body" or "attachment"

Body part must be a text data and possible choices for encoding are text/plain or application/xml. B2bi does not support text/html body parts.

The above options aply to generaic email only. For AS1 the payload is always sent as attachment regardless of PayloadLocation attribute value.

Optionally you can add a payload as attachment and a body text describing the payload. It is possible with pickup trough MMD file. Here is an example MMD to pickup the body text and the attachment:

<?xml version="1.0" encoding="UTF-8"?>

<MessageMetadataDocument protocol="generic" protocolVersion="1.0">

<Metadata name="From">SenderRoutingID</Metadata>

<Metadata name="To">ReceiverRoutingID</Metadata>

<Metadata name="SubjectHeader">Email Subject</Metadata>

<MessagePayloads>

<Payload id="1" packagingLocation="Body">

<MimeContentID>1</MimeContentID>

<MimeContentType>text/plain</MimeContentType>

<Location type="filePath">localpath</Location>

</Payload>

<Payload id="2" packagingLocation="attachment">

<MimeContentType>application/xml</MimeContentType>

<Location type="filePath">localpath</Location>

</Payload>

</MessagePayloads>
