Interchange Control Trailer


The Interchange Control Trailer is a key component within an EDI interchange as it provides essential information about the completion of the data exchange. It includes details such as an end-of-interchange identifier, the total number of segments in the interchange, and other relevant information. The Control Trailer segment ensures proper structure of the interchanges and helps validate the received data.

Use Case:

An example use case for the Interchange Control Trailer can be found in the logistics industry. Let’s consider a scenario where a transportation company sends an interchange to a warehouse for shipment confirmation. The Interchange Control Trailer segment would be included in the interchange to indicate the completion of the transaction and to confirm the integrity and accuracy of the sent data.

Example code:

import ediconnect

def create_interchange(header_data, transaction_data):
# Create the interchange header
interchange_header = ediconnect.create_interchange_header(header_data)

# Create the transaction data
transaction = ediconnect.create_transaction(transaction_data)

# Create the interchange control trailer
interchange_trailer = ediconnect.create_interchange_trailer()

# Combine the interchange components
interchange = interchange_header + transaction + interchange_trailer

return interchange

def process_interchange(interchange):
# Extract and process the interchange control trailer
interchange_trailer = interchange[-1] # Assuming the interchange control trailer is the last segment

# Extract and process the transaction data
transaction = interchange[1:-1] # Assuming the transaction data is between the header and trailer

def process_interchange_trailer(interchange_trailer):
# Process the interchange control trailer
# …

def process_transaction(transaction):
# Process the transaction data
# …

# Example header data
header_data = {
sender’: ‘CompanyA’,
receiver’: ‘CompanyB’,
‘creation_date’: ‘2023-07-01’,
# Add more header details as needed

# Example transaction data
transaction_data = {
‘transaction_type’: ‘Order’,
‘order_number’: ‘ORD123’,
‘customer’: ‘CustomerX’,
# Add more transaction details as needed

# Creating the interchange
interchange = create_interchange(header_data, transaction_data)

# Processing the interchange

Best Practices:

  1. Ensure that the Interchange Control Trailer segment is present and correctly positioned at the end of each interchange.
  2. Verify and validate the integrity of the Interchange Control Trailer segment to confirm the accuracy and completeness of the received data.
  3. Clearly document the meaning and attributes of each data element within the Interchange Control Trailer.
  4. Perform testing and simulations to ensure the proper functioning of the Interchange Control Trailer segment.
