GDSN - Global Data Synchronization Network
|
Imagine, as a manufacturer or a retailer that you could continuously align
product,location and program information with your trading partners. Imagine that
this information could be communicated to your trading partners through simpler,
faster and more accurate transactions all along the supply chain allowing for the
right amount of goods to become available at the right place and at the right time.
Achieving this efficiency is not
utopia but can be achieved NOW provided you decide
to act NOW and to prepare your company for Global Data Synchronization (GDS). Not
interested? Think again, otherwise
you stand to miss this unique opportunity to be best positioned in tomorrow's global
and hyper competitive market place.
The GDSN vision is being realized
today by hundreds of retailers and manufacturers worldwide who are reaping the benefits
of live implementations. Global Registry membership covers multiple sectors across
North America, Latin America, Europe and Asia Pacific.
Don’t get left behind, get involved
today and transform your supply chain into a business asset.
The vision of the GDSN is now reality!
What is Global Data Synchronization (GDS)?
In a trading relationship, the first
thing you need to define is WHO and WHERE you are and WHAT you have to trade in
WHICH target market. To answer these questions, EAN.UCC has developed identification
keys that are the Global Location Number (GLN) and the Global Trade Item Number
(GTIN). These keys have to be
used properly by following EAN.UCC rules such as:
o
GTIN allocation rules (When to change a GTIN?)
o
GLN allocation rules (How to assign a GLN?)
o
Bar Code or Radio Frequency (RFID) Specifications (How is the key physically carried?)
o
Other rules (Symbol placement, Physical package attribute, etc.)
As these keys alone do not provide
sufficient information, they are completed by attributes describing them; such as
item or location (party) description, price, size, pack, name, address, etc. These
standardised attributes that support trading partner relationships are called Master
Data (common across multiple items such as the GTIN) or Transactional Data (trading
partner specific such as the quantity ordered in a purchase order). One of these
attributes that play a key role in GDSN is the Global Product Classification (GPC)
Code indicating which kind of product the trade item is and to which group of products
it belongs. In GDSN, every GTIN has to be classified using GPC.
In addition, all the information
(definition, format, etc.) for all attributes is stored in a central repository
that is called the
Global Data
Dictionary (GDD).
This ensures the consistent use of
these attributes in all e-business standards developed by EAN.UCC.
Why Synchronizing?
Today, trading partners are facing
high, unnecessary costs due to master data problems, such as supply chain information
inefficiencies and inaccurate data in transactions. Invoices with errors are responsible
for a large part of these costs. In addition, globalisation of trade has generated
an accelerated need for the smooth inter-company flow of goods and better control
of supply chain processes, which can be achieved through synchronised communication
among trading partners.
By continuously synchronising/harmonising
the master data, between your system and your trading partner's systems, you will
ensure that master data is the same in all systems. This will allow you to trade
globally, increase data accuracy between you and your trading partners and drive
costs out of your supply chain. It is important to note that GDS is a robust foundation
upon which the full benefits of electronic collaboration can be achieved and scaled.
Electronic collaboration without data synchronization will merely accelerate the
exchange of bad master data between trading partners. GDS is also a pre-requisite
for the Electronic Product Code (EPC) based on radio frequency identification (RFID).

Without clean, synchronised master
data, EPC and RFID technology will just enable even faster transactions of the wrong
information. It is also very important to note that greater financial return can
be achieved as companies expand the scope of data synchronisation and collaboration.
For instance, by synchronizing price
information as well as item and location (party) information you can further reduce
costs within the Supply Chain. Due to the fact that the majority of non-quality
orders and invoice deductions are due to inaccurate pricing information, the benefits
related to order quality and invoice matching are even more pronounced.
Of course, to enable GDS, a Network
is needed; this is what we call the Global Data
Synchronisation Network (GDSN)
What is GDSN and How does
it work?
The Global
Data Synchronization Network (GDSN) is a concept that was developed by various
industry
groups, including the Global Commerce Initiative (GCI), Global Standard1 (GS1),
to help industry streamline supply chain transactions and reduce supply chain costs.
The GDSN is an Internet-based, interconnected network of interoperable data pools
and a Global Registry, the GS1 Global Registry, that enables companies around the
world to exchange standardized and synchronized supply chain data with their trading
partners. The GDSN assures that data exchanged between trading partners is accurate
and compliant
with universally supported standards. The GDSN consists of trading
partners (supplier and retailers), data pools (services that hold and process trading
partner data), and the GS1 Global Registry (a worldwide directory to help the GDSN
community locate data sources and manage ongoing synchronization relationships between
trading partners).
One
of the key advantages of the GDSN is that trading partners have a single point of
entry to the GDSN through
the certified data pool of their choice therefore avoiding having to pay subscriptions
to multiple data pools either within the same geographic location or across multiple
geographic locations. Therefore, trading partners access to the GS1 Global Registry
is only available through a certified data pool. It has to be noted that trading
partners can act as their own certified data pools. Within the GDSN, Catalogue Items
are identified using the GTINs and GLNs of the data source (supplier), and target
market while Parties are identified using a GLN.

Some key aspects of the GDSN are:
o
This model supports a rich
network of interoperable data pools
o
Suppliers and Retailers have a single
point of entry to the GDS Network
o
Suppliers and Retailers do not have
direct access to the GS1 Global Registry, unless they act as their own data pool
o
Trade Items are identified in the
GDSN using the unique combination of GTIN, GLN of the data source, and Target Market
(TM).
o
Parties are identified in the GDSN
using GLN.

Benefits For Manufacturers
& Retailers
In a recent case study (The Case for
Global Standards) performed by Cap Gemini Ernst &Young under the leadership of the Global Commerce Initiative (GCI)
Steering Group, it was demonstrated that adopting and implementing GDS would lead
to a one to three percent savings in supply chain costs. As indicated earlier, long-term
benefits are even greater, as GDS is a corner stone for large scale implementation of collaborative business processes and also for the Electronic Product Code (EPC)
based on radio frequency identification (RFID). Identification of the benefits makes
it apparent that retailers and manufacturers stand to gain in equal measure. What
is more, it is not only global players that will benefit from global standards such
as GTIN, GLN, GPC and GDSN. Trading partners of all sizes will reap benefits from
increased reach and synchronization.

Item Data Pools
Item data pools
are electronic catalogues of standardized item data. They serve both as a source
and/or recipient of master data and can be run by an EAN Member Organization, supplier,
customer, exchange or service provider. Today, several catalogues exist that have
been operating for several years Eight of these catalogues are already on the GDSN.
These are CABASnet, Click Commerce (formerly bTrade Inc.), Global eXchange Services
(GXS), Sinfos, Sterling Commerce, Transora, UCCnet and Worldwide Retail Exchange
(WWRE). In time it is expected that many more electronic catalogues will become
compliant with the EAN.UCC standards.

GS1 Global Registry
The GS1 Global Registry
is the central directory for providing information for subscription sharing for
achieving data pool interoperability and Catalogue Item uniqueness by the registration
of items and parties.
The GS1 Global Registry became operational
on August 1, 2004 and has the following roles:
o Guarantees efficiently the uniqueness of the Catalogue Item
(GTIN + GLN + target market) for a particular data source.
o Holds the information on the source data pool where the details
of the GTIN reside. This data is only held once in the network.
o Ensures that all the data pools in the network are complying
with a common basic set of validation rules that support data integrity in the system.
This is achieved by allowing only data from EAN.UCC certified data pools to be registered
in the GS1 Global Registry.
o Holds the information about who has subscribed to Trade Item
or Party data. This data is only held for the purpose of acting as a central repository.
Data pools receive subscriptions based on a match of the Trade Item or Party data
Registered with the GS1 Global Registry.
o Allows data pools to direct global search requests to the
GS1 Global Registry subscription service.The search can work on GTIN, GLN, target
market and Global Product Classification
(GPC) schema.
A new legal entity named GS1 Global
Registry Inc. (GRI) has been created to provide the GS1 Global Registry service.
The Oversight Committee, which currently includes seventeen senior executives from
manufacturing, retailing, and GS1 Member Organisations, governs this legal entity
and ensures that the EAN.UCC Information Network and the GS1 Global Registry service
meet the needs of the entire global community.
