Configuring Send Settings for Outbound X12 Messages

Partner Manager enables you to configure the X12 envelope parameters, delimiters, validation rules, character encoding, and control numbers to apply when sending an outbound X12 transmission to a partner.

To configure a partner’s X12 send settings:

  1. In the navigation menu, select Partners.

  2. Select the partner for whom you want to configure the settings.

  3. In the Validation and acknowledgment settings section’s Send to <partner-name> column, click X12.

  4. In the menu on the left, select the setting to configure:

  5. Click Save.

The values you configure in the partner’s settings page are used by default for all X12 messages going to that partner.

You can override the settings you configure at the partner level, with the exception of TA1 and control numbers, or at the message flow level by selecting the Custom option while creating an outbound message flow.

It can take up to five minutes for your configuration changes to sync with Mule.

General Settings

Use the following settings to configure the transaction usage, specify the responsible standards agency, and enforce length limits and conditional relationship validations:

Setting Description Default Value

Usage indicator (ISA15)

Indicates if the X12 transaction sent is for testing, production, or information only.

Possible values include:

  • I - Information

  • T - Test

  • P - Production

  • P - Production
    For production environments

  • T - Test
    For sandbox environments

Responsible agency code (GS07)

Define the standards agency responsible for the standard in the GS segment.

Possible values include:

  • T - Transportation Data Coordinating Committee (TDCC)

  • X - Accredited Standards Committee X12


Enforce length limits

If selected, any data elements with a length outside of the definition in the X12 schema cause the generation of the X12 transaction to fail.


Enforce conditional relationship validations

If selected, any missing conditional data elements cause the generation of the X12 transaction to fail.


Enforce code set validations

If selected, Partner Manager enforces X12 code set validations, as defined in the X12 schemas.


Authorization Settings

Use the following settings to configure the authorization and security qualifier for the transactions:

Setting Description Default

Authorization qualifier (ISA01)


Security qualifier (ISA03)


TA1 Acknowledgment Settings

Use the following settings to configure whether a technical acknowledgment is required, and the receive endpoint for the acknowledgment:

Setting Description Default

Expect TA1 for each transmission sent to <partner>

If selected, sets the value in ISA14 to 1 on the generated X12 payload, indicating that a Technical acknowledgment (TA1) is required.



When the option to expect a TA1 is selected, click Select to specify the Receive from <partner> endpoint. The acknowledgment will be received as an inbound transmission.


Global Control Numbers

Partner Manager applies a global control number at the partner level on the X12 interchanges and functional groups generated from outbound message flows. These control numbers are sequenced across all message types (including functional acknowledgments) that are sent to a partner.

The control number starts with a default value of 1, and is sequentially increased as your organization begins sending outbound transmissions.

To set the control number sequence value to a different number to maintain sequencing and avoid duplication:

  1. Click Change and enter the desired control number.

  2. Click Save.

It can take up to five minutes to apply the change at runtime.

Character Set & Separators

Use the following settings to set the character encoding and delimiters for the generated X12 payload:

Setting Description Default Value

Character set

Set of characters allowed in string data.


Character encoding

Character encoding for messages.


Segment terminator

Segment terminator character.


Data element separator

Data element separator character.


Component element separator (ISA16)

Component element separator character.


Line ending between segments

Character to use for line endings between segments to improve the readability of the output message text. Possible values include:

  • NONE

    Generates the EDIFACT payload as a single line with segments separated by this character

  • CR

    Carriage return

  • CRLF

    Carriage return and line feed

  • LF

    Line Feed


Use segment line ending in last line

If Yes, Partner Manager applies the segment line ending character to the last segment in the payload.
