EDI Context Properties

The message context properties in the EDI global property schema are publicly exposed so you can use them in operations such as message routing. These context properties are defined in PropertySchema.xsd in the Microsoft.BizTalk.Edi.BaseArtifacts assembly. The namespace for the properties is http://schemas.microsoft.com/ Edi/PropertySchema. If they are promoted, these message context properties are available as Edi.<Property Name> in the Filters page of the Send Port Properties Dialog Box in the UI guidance and Developers reference.

Context properties list

The EDI context properties are also available in an orchestration, as long as a reference to the Microsoft.BizTalk.Edi.BaseArtifacts assembly has been added to the orchestration project.

Name Type Description
AK901 string Indicates whether the functional group identified in the AK1 segment of the acknowledgment was accepted or rejected (X12 997 ACK only).

ErrorDescription string For a suspended message, contains a copy of the error message (similar to the message in the EventViewer).
GS_Segment string The complete GS (functional group) segment (X12).

The EDI receive pipeline writes this property to the context when the interchange is split as transaction sets, not when the interchange is preserved.
GS01 string The Functional Identifier Code (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched interchange being preserved).

ISA_Segment string The complete ISA (interchange control header) segment (X12).

BizTalk Server writes this property to the context when the interchange is split as transaction sets, not when the interchange is preserved.

This property contains security/authorization information (ISA2, Authorization Information, and ISA4, Security Information) that may lead to information disclosure. You can use the Mask security/authorization/password information property (in the Validation and ACK Generation page) to replace each character in the ISA2 and ISA4 fields with a “#” character. This is a one-way process: the “#” characters cannot be converted to actual characters.

The EDI receive pipeline writes this property to the context when the interchange is split as transaction sets, not when the interchange is preserved.
ISA05 string The Interchange Sender Qualifier (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched interchange being preserved).
ISA06 string The Interchange Sender ID (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched interchange being preserved).
ISA07 string The Interchange Receiver Qualifier (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched interchange being preserved).
ISA08 string The Interchange Receiver ID (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched interchange being preserved).
ISA15 string The Usage Indicator (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched being preserved).
IsResendControlMessage int Used by the AS2 engine to indicate that an AS2 message send should be retransmitted, as an MDN response has not been received within the configured time.
IsSystemGeneratedACK boolean Indicates that the message is an acknowledgment (X12 TA1 or 997, or EDIFACT CONTRL) that was generated by the system. Can be set to True or False.

This is a message context property that is available as EDI.IsSystemGeneratedACK in the Filters page of the Send Port Properties dialog box.

ReceiverPartyNameForSend String Used by the EDI send pipeline for agreement resolution for outbound documents.
ReuseEnvelope boolean Indicates whether an interchange is preserved or split. If the interchange is preserved, BizTalk Server will reuse the envelope when processing the interchange for sending.
SenderPartyName String Written by EDI receive pipeline. Specifies the name of the source partner provided in the agreement to which the inbound message is resolved. For a fallback agreement this value would be BTS-SENDER.
SenderPartyNameForSend String Used by the EDI send pipeline for agreement resolution for outbound documents.
ST01 string The Transaction Set Identifier Code (X12)

The EDI receive pipeline promotes this property to the context (if the interchange is not a batched interchange being preserved).
ST03 string The Version/Release/Industry Identifier Code (X12)

The EDI receive pipeline writes this property to the context when the interchange is split as transaction sets, not when the interchange is preserved.

This property contains security/authorization information (UNB6.1 and UNB6.2) that may lead to information disclosure. You can use the Mask security/authorization/password information property to replace the value in the UNB6.1 and UNB6.2 fields with a “#” character. Note that the “#” character cannot be converted to actual characters.

Extracting Individual Fields from the Segment Context Properties

Some properties are not written or promoted to the message context by the EDI receive pipelines as individual properties, but only as part of a segment string. This is done for performance reasons, because property promotion has an impact on performance. For example, the ISA5, ISA6, ISA7, ISA8, and ISA15 fields of the ISA segment are promoted by the receive pipelines as individual properties, but the rest of the ISA fields are only written to the message context as part of the ISA_Segment property. These properties are written or promoted only when ReuseEnvelope is not set to True, indicating that a received batched interchange is not being preserved.

If you need an individual field of one of the segments (ISA, GS, UNB, UNG, or UNA) to be written to the message context, but this individual field is not written to the message context by default, you will need to write a custom component to write it to the message context. This custom component needs to parse the segment fields and write an individual field to the message context.

The Message Enrichment sample shows how to use a parser to extract individual fields from the segments and write them to the context. This sample is included in the <drive>:\Program Files\Microsoft BizTalk Server\SDK\Samples\EDI\MessageEnrichment. For more information, see Message Enrichment Sample (BizTalk Server Sample).
