Segment Hierarchy

Segment Hierarchy


In the context of EDI, segment hierarchy refers to the specific order in which segments appear within a transaction set. This hierarchy determines the correct structure and arrangement of segments within EDI messages and ensures their proper interpretation and processing of business information.

Segment hierarchy is crucial for achieving consistent and reliable communication between trading partners in the exchange of EDI messages. By adhering to the segment hierarchy, information is transmitted in a well-defined sequence, and each segment is placed correctly within the EDI message.

Use case:

A typical use case for segment hierarchy can be found in the process of transmitting a purchase order from a customer to a supplier. In this scenario, segments may be organized in the following order: “Order Header Segment,” “Product Detail Segment,” “Quantity Segment,” “Price Segment,” and “Order Closing Segment.” By following the segment hierarchy, order-related information is properly transmitted and easily interpreted by the receiving system.

Example of script code:

import ediconnect

# Create a new transaction set
transaction_set = ediconnect.TransactionSet()

# Add segments in the desired order
transaction_set.add_segment(‘OrderHeaderSegment’, [‘OrderNumber’, ‘CustomerName’])
transaction_set.add_segment(‘ProductDetailSegment’, [‘ProductCode’, ‘Quantity’])
transaction_set.add_segment(‘PriceSegment’, [‘UnitPrice’, ‘TotalPrice’])
transaction_set.add_segment(‘EndOrderSegment’, [‘OrderStatus’])

# Get the formatted transaction set content
formatted_set = transaction_set.get_formatted_transaction_set()

# Send the transaction set using EDIconnect
edi_connection = ediconnect.Connection(username=’username’, password=’password’, endpoint=’’)
response = edi_connection.send_transaction_set(transaction_set)

# Check the response
if response.success:
print(“Transaction set sent successfully!”)
print(“Error sending the transaction set:”, response.error_message)

Best practices:

  1. Refer to the relevant EDI standards and guidelines to understand and follow the specified segment hierarchy for the transaction sets being used.
  2. Consistently adhere to the defined segment hierarchy to ensure proper communication and interoperability with trading partners.
  3. Document and maintain the segment hierarchy structure for each transaction set to facilitate accurate implementation and interpretation.
  4. Validate transaction sets against the defined segment hierarchy to ensure compliance and prevent data errors.
  5. Utilize an EDI solution provider like EDIconnect, which offers comprehensive tools and support for managing segment hierarchy, ensuring smooth and reliable EDI transactions.
