ISA Segment Definition Page (EDI Properties)

The properties included in this page define how BizTalk Server generates the ISA segment for an X12-encoded interchange that it sends to the party. An ISA segment is the interchange control header for an X12-encoded interchange. The role of the party is as an interchange receiver from BizTalk; the role of BizTalk is as an interchange sender to the party.

This page of the EDI Properties dialog box is displayed by right-clicking a party in the Parties node of the BizTalk Server Administration Console, clicking EDI Properties, and then clicking ISA Segment Definition Properties under the X12 Properties, Party as Interchange Receiver, and X12 Interchange Envelope Generation nodes in the console tree.

For the BizTalk Server runtime, the length of alphanumeric ISA fields is fixed. However, for the Partner Agreement Manager User Interface, you may enter a single character for an alphanumeric ISA field. BizTalk Server will pad these fields with trailing space characters to ensure compliance with standards requirements.

ISA1-2 (Authorization qualifier and information)

Select a value for the Authorization qualifier. The default value is 00 - No Authorization Information Present. This is a required field.

If you select a value other than 00 for the Authorization qualifier, enter a value for the Authorization information. There is no default value for Authorization information. This is an optional alphanumeric field, with a minimum of one character and a maximum of 10 characters.

ISA3-4 (Security qualifier and information)

Select a value for the Security qualifier. The default value is 00 - No Security Information Present. This is a required field.

If you select a value other than 00 for the Security qualifier, enter a value for the Security information. There is no default value for Security information. This is an optional alphanumeric field, with a minimum of one character and a maximum of 10 characters.

ISA5-6 (Sender qualifier and identifier)

Select a value for the Sender ID qualifier.

Enter a value for the Sender identifier. This is an alphanumeric field, with a minimum of one character and a maximum of 15 characters.

By default, each of these properties is a null. Once you have entered a value for either of these properties, you can replace it with a different value, but you cannot return the field to a null value.

ISA7-8 (Receiver qualifier and identifier)

Select a value for the Receiver ID qualifier.

Enter a value for the Receiver identifier. This is an alphanumeric field, with a minimum of one character and a maximum of 15 characters.

By default, each of these properties is a null. Once you have entered a value for either of these properties, you can replace it with a different value, but you cannot return the field to a null value.

The combination of the ISA7 and ISA8 fields must be unique.

Standard identifier

Select the radio button to specify a Standard identifier instead of a repetition separator, and then select a value for the Standard identifier from the drop-down list.

The default value for the ISA11 usage radio buttons is Standard identifier.

The default value for the standard identifier is U - U.S. EDI Community of ASC X12, TDCC and UCS.

Repetition separator

Select the radio button to specify a Repetition separator instead of a Standard identifier, and then enter a single character for the repetition separator. The repetition separator is used to separate segments that repeat within a transaction set.

The default value for the ISA11 usage radio buttons is Standard identifier, not Repetition separator.

If Repetition Separator is selected, the default value for the repetition separator is ^.

This element is limited to the values in the ASCII character set.

Data element

Select the type of the Data element separator (either Char or Hex), and then enter a single character for the separator. This character separates data elements within an EDI message segment. The character is used to separate composite data elements consisting of two or more simple data elements, and it is used to separate simple data elements that are not part of a composite. In an X12 interchange, the data element separator is defined as the character in the fourth character position of the interchange.

The default value is * if the type is Char, and 2a if the type is Hex.

This element is limited to the values in the ASCII character set. This property is not validated against the X12 character set defined in the General page.

ISA16 (Component separator)

Select the type of the Component element separator (either Char or Hex), and then enter a single character for the separator. This character separates the lowest level of data within an EDI message segment: simple data elements within composite data elements.

The default value is : if the type is Char, and 3a if the type is Hex.

This element is limited to the values in the ASCII character set. This property is not validated against the X12 character set defined in the General page.

Segment terminator

Select the type of the Segment terminator (either Char or Hex), and then enter a single character for the separator. This character indicates the end of an EDI segment. In an X12 interchange, the segment terminator is defined as the character in the last character position of the ISA segment.

The default value is ~ if the type is Char, and 7e if the type is Hex.

You can leave this data element empty, but if you do, you need to designate a suffix.

This element is limited to the values in the ASCII character set. This property is not validated against the X12 character set defined in the General page.

Suffix

Select the Suffix to be used with the Segment identifier, either None, CR (carriage return), LF (line feed), or CR LF (carriage return/line feed).

If you designate a Suffix, the Segment terminator data element can be empty. If the Segment terminator is left empty, you must designate a suffix.

The segment terminator and suffix pair can be any of the following values:

  • Segment terminator

  • Segment terminator + carriage return

  • Segment terminator + line feed

  • Segment terminator + carriage return/line feed

  • Carriage return

  • Line feed

  • Carriage return/line feed

The default value is None.

ISA12 (Control version)

Select a value for the Control version number.

The default is 00401 - Standards Approved for Publication.

Required field. Minimum five characters, maximum five characters.

ISA13 (Interchange control number)

Select Edit, and then enter a value for the Interchange control number. BizTalk Server will set the interchange control number for the next interchange sent to this number, and will increment this number for each subsequent interchange. BizTalk Server will update this UI field to the next interchange control number that it will use in an interchange.

The default value is 1.

Required numeric field. Minimum one character, maximum nine characters.

ISA14 (Technical acknowledgment required)

Select to indicate that the receiving party must return a technical acknowledgment in response to an interchange sent by BizTalk Server.

The default is cleared.

ISA15 (Usage indicator)

Select to indicate whether an interchange generated by BizTalk Server is information, production data, or test data.

The default is T - Test Data.
