The Transaction Header Group 2TRG in an AL3 (ACORD AL3) file is critical because it provides important control information for the entire transaction being transmitted.
What is the Transaction header group(2TRG)?
The Transaction Header Group includes important details that enable the receiving system to identify where to send the transaction, understand what type of transaction it is, and handle it correctly. It also helps the system reply properly to the sender. The total length of this group is 212, which ensures that the data in this group can be of only 212 characters.
Why is it important?
Identifies the Transaction
It includes the transaction code, which tells the receiver what kind of transaction this is (e.g., new business, cancellation, and renewal).
This Information can be found in the 2TRG25 element of the Trancation header group
- Element name: Cycle/Business Purpose
Element definition: The Cycle/Business Purpose is a 3-letter code that shows the reason or type of business activity for the transaction.
Example: NBS, PCH, RWL, and REI
This Element is mandatory; without this element, any AL3 file is incomplete.
Route the Data Correctly
It provides details that the system uses to send the transaction to the right department or internal process.
This Information can be found in the 2TRG04, 2TRG10, and 2TRG10.
- Element name: Automation Level
Element Definition: The Automation Level shows how automated the system was when the transaction was created. It tells how easily the data can be processed by a computer, but it doesn’t change the actual data in the transaction - Element name: Initial Transaction Mode
Element Definition: The Initial Transaction Mode tells the receiver what the sender wants to do in the first transaction of a processing cycle. - Element name: Origination Reference Information
Element Definition: The Origination Reference Information is a custom text field provided by the sender in the first transaction of a processing cycle. It can be used to store things like a file name, disk location, or any internal reference.
Version Control
- Often includes indicators for the version of the AL3 format being used.
- Ensures backward/forward compatibility and prevents system errors during processing.
This Information can be found in the 2TRG01 Element.
- Element name: Transaction Structure Standard Version Number
Element Definition: This data element shows the version number of the ACORD Transaction Structure Standard (Standard No. 910) that was used to build the transaction.
Supports Multi-Transaction Files
- In files containing multiple transactions, each one begins with its own Transaction Header Group.
- This allows batch processing while maintaining transaction-level integrity.
