02/02/2021

Five types of context properties apply to AS2 messages in BizTalk Server:

Context properties in the EdiIntProperties.xsd schema
Context properties internal to BizTalk Server
Context properties internal to BizTalk MIME
Context properties internal to AS2
Context properties internal to AS2 Status Reporting

Context Properties in the EdiIntProperties.xsd schema

The message context properties in the EDI/INT global property schema are publicly exposed so you can use them in operations such as message routing. These context properties are defined in EdiIntProperties.xsd in the Microsoft.BizTalk.Edi.BaseArtifacts assembly. The namespace for the properties is http://schemas.microsoft.com/BizTalk/2006/as2-properties. If they are promoted, these message context properties are available as EdiIntAS.<Property Name> in the Filters page of the Send Port Properties dialog box.

Name	Type	Description
AS2From	string	Contains the AS2-From AS2 header value that represents the sender’s name.
AS2PayloadContentType	string	Contains the content type of the payload message.
AS2To	string	Contains the AS2-To AS2 header value that represents the receiver’s name.
DispositionMode	string	Contains the MDN disposition mode value. Both this context property and the DispositionType context property must be promoted in order for an MDN to be generated.
DispositionType	string	Contains the MDN disposition type value. Both this context property and the DispositionMode context property must be promoted in order for an MDN to be generated.
IsAS2AsynchronousMdn	boolean	Indicates that the message is an asynchronous MDN.
IsAS2FailedMessage	boolean	Indicates that the incoming AS2 message has failed processing in AS2, causing the payload message to be suspended.
IsAS2Http200OKResponse	boolean	Set on a message that will be generated as an HTTP 200 OK response message. It is used when an MDN will not be generated for an AS2 message or when the MDN is being sent asynchronously.
IsAS2MdnResponseMessage	boolean	Indicates that the message is an MDN response message.
IsAS2MessageDuplicate	boolean	Indicates that the incoming AS2 message has previously been received.
IsAS2MessageCompressed	boolean	Indicates that the incoming AS2 message was compressed.
IsAS2MessageEncrypted	boolean	Indicates that the incoming AS2 message was encrypted.
IsAS2MessageSigned	boolean	Indicates that the incoming AS2 message was signed.
IsAS2PayloadMessage	boolean	Indicates that this message contains the decoded AS2 message content and should be processed as the payload.
MDNAsyncURI	string	Contains the Receipt-Delivery-Option value that is used in sending asynchronous MDN response messages.
MessageId	string	Contains the AS2 Message ID that is included in the headers of the AS2 message.
OriginalMessageId	string	Contains the Message ID of the original AS2 Message. This context property is part of an MDN message and is used for correlating AS2 Messages and their MDN Responses.
PreservedFileName	string	Contains the original file name of the message. This context property will only be populated if the incoming message includes filename information as part of the Content-Disposition MIME header.
SendMDN	boolean	Set to true if an MDN message should be generated.

Context Properties Internal to BizTalk Server

The following message context properties are not publicly exposed, so you cannot use them for operations such as message routing. However, they can be viewed in suspended and tracked messages. The namespace for these context properties is http://schemas.microsoft.com/BizTalk/2006/system-properties.

Name	Type	Description
IgnoreSslCertificateNameMismatchErrors	boolean	Directs BizTalk Server HTTP processing to ignore SSL name mismatch errors during processing.
KeepAlive	Boolean	Controls the behavior of the HTTP Keep Alive functionality.
TreatEPMSuspendAsSuccess	boolean	Directs BizTalk Server to treat a suspended message as a success message when processing on a two-way HTTP inbound connection.
IsSolicitResponse	boolean	Set by BizTalk Server and indicates that the message is a solicit-response message.

Context Properties Internal to BizTalk MIME

Name	Type	Description
IsMultipartReport	boolean	Causes the BizTalk Server MIME encoder to generate a multipart/report message.
SuppressMimeVersionFromMultiPartMessage	boolean	Causes the BizTalk Server MIME encoder to suppress the MIME Version header in each part of a multipart message.

Context Properties Internal to AS2

Name	Type	Description
MicHashAlgorithm	string	Contains the hash algorithm used when computing the MIC hash value.
ReceivedContentMic	string	Contains the calculated MIC hash value.

Context Properties Internal to AS2 Status Reporting

Name	Type	Description
InterchangeControlNo	string	The interchange control number from an EDI interchange. This property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
InterchangeDate	string	The interchange date from an EDI interchange. This property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
InterchangeTime	string	The interchange time from an EDI interchange. This message context property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
ReceiverID	string	The interchange receiver ID from an EDI interchange. This property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
ReceiverQualifier	string	The interchange receiver qualifier from an EDI interchange. This property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
SenderID	string	The interchange sender ID from an EDI interchange. This property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
SenderQualifier	string	The interchange sender qualifier from an EDI interchange. This property is read from a message during AS2 encoding and is used to report an AS2 Interchange Activity.
