Part IV
Explain In Detail
Question 1.
Briefly explain various types of EDI.
Answer:
The types of EDI were constructed based on how EDI communication connections and the conversion were organized. Thus based on the medium used for transmitting EDI documents the following are the major EDI types.
- Direct EDI
- EDI via VAN
- EDI via-FTP/VPN, SFTP, FTPS
- Web EDI
- Mobile EDI
- Direct EDI/Point-to-Point
It is also called as Point-to-Point EDI. It establishes a direct connection between various business stakeholders and partners individually. This type of EDI suits to larger businesses with a lot of day to day business transactions.
EDI via VAN:
EDI via VAN (Value Added Network) is where EDI documents are transferred with the support of third-party network service providers. Many businesses prefer this network model to protect them from the updating ongoing complexities of network technologies.
EDI via FTP/VPN, SFTP, FTPS:
When protocols like FTP/VPN, SFTP, and FTPS are used for the exchange of EDI-based documents through the Internet or Intranet it is called EDI via FTP/VPN, SFTP, FTPS.
Web EDI:
Web-based EDI conducts EDI using a web browser via the Internet. Here the businesses are allowed to use any browser to transfer data to their business partners. Web-based EDI is easy and convenient for small and medium organizations.
Mobile EDI:
When smartphones or other such handheld devices are used to transfer EDI documents it is called mobile EDI. Mobile EDI applications considerably increase the speed of EDI transactions.
Question 2.
What are the advantages of EDI?
Answer:
- EDI was developed to solve the problems inherent in paper-based transaction processing and in other forms of electronic communication.
- Implementing an EDI system offers a company greater control over its supply chain and allow it to trade more effectively. It also increases productivity and promotes operational efficiency.
The following are the other advantages of EDI.
- Improving service to end-users
- Increasing productivity
- Minimizing errors
- Slashing response times
- Automation of operations
- Cutting costs
- Integrating all business and trading partners
Question 3.
Write about the structure of EDIFACT.
Answer:
- EDIFACT is a hierarchical structure where the top level is referred to as an interchange, and lower levels contain multiple messages.
- The messages consist of segments, which in turn consist of composites.
- The final iteration is a data element.
Segment Tables
- The segment table lists the message tags.
- It contains the tags, tag names, requirements designator, and repetition field.
- The requirement designator may be mandatory (M) or conditional (C).
- The (M) denotes that the segment must appear at least once. The (C) denotes that the segment may be used if needed.
- Example: CIO indicates repetitions of a segment or group between 0 and 10.
EDI Interchange
- Interchange is also called an envelope.
- The top-level of the EDIFACT structure is Interchange.
- An interchange may contain multiple messages. It starts with UNB and ends with UNZ
EDIFACT message
- The basic standardization concept of EDIFACT is that there are uniform message types called United Nations Standard Message (UNSM).

- The message types, all of which always have exactly one nickname consisting of six uppercase English alphabets.
- The message begins with UNH and ends with UNT

- CONTRL- Syntax Check and Confirmation of Arrival of Message
- APERAK – Technical error messages and acknowledgment
Data exchange
- CREMUL – multiple credit advice
- DELFOR- Delivery forecast
- IFTMBC – Booking confirmation
EDIFACT Segment
- It is the subset of messages.

EDIFACT Elements
- The elements are the piece of actual data.
- These data elements may be either simple or composite.

Detailed Answers
Question 1.
Explain EDI standards?
Answer:
EDI Standards:
- The standard is the most critical part of the entire EDI. Since EDI is the data transmission and information exchange in the form of an agreed message format, it is important to develop a unified EDI standard.
- The EDI standard is mainly divided into the following aspects: basic standards, code-standards, message standards, document standards, management standards, application standards, communication standards, and security standards.
- The first industry-specific EDI standard was the TDCC published by the Transportation Data Coordinating Committee in 1975.
- Then other industries started developing unique standards based on their individual needs. E.g. WINS in the warehousing industry.
- Since the application of EDI has become more mature, the target of trading operations is often not limited to a single industry.
- In 1979, the American National Standards Institute Accredited Standard Committee (ANSI ASC) developed a wider range of EDI standards called ANSI XI2.
- On the other hand, the European region has also developed an integrated EDI standard. Known as GTDI (Guideline for Trade Data Interchange).
- ANSI X12 and GTDI have become the two regional EDI standards in North America and Europe respectively.
- After the development of the two major regional EDI standards and a few years after the trial, the two standards began to integrate and conduct research and development of common EDI standards.
- Subsequently, the United Nations Economic Commission for Europe (UN/ECE/WP.4) hosted the task of the development of international EDI standards. In 1986, UN/EDIFACT is officially proposed. The most widely used EDI message standards are the United Nations EDIFACT and the ANSI X12.
