MSH Field Overrides

Every HL7 message has a message header. Using BizTalk Accelerator for HL7, you can override any message header value based on your business need. You use the BTAHL7 Configuration Explorer MSH Map tab to manually over ride message header values without using any mapping or orchestration.

Configuring MSH Field Overrides

You use the MSH Map tab in BTAHL7 Configuration Explorer (under the high-level Parties tab) to configure MSH field overrides. When you enter a value for an MSH field using this tab, that value overrides the existing MSH value in an outbound HL7 message that BTAHL7 sends to the selected party. You can type new values for many MSH fields, or select values from a drop-down list for the MSH15 and MSH16 fields.

The following figure shows the BTAHL7 Configuration Explorer MSH Map tab.
