This is really very simple basic information.. it is good information for learners.. Thanks Rag

It depends what and how you are going to use EDI messaging.Oracle have 2 similar product which you can use. they are E-Commerce gateway,XML Gateway

But it again its depends how your trading patner uses and sending the details.

Most modern translators can deal with XML-EDI-XML transforms.

Here is simple flow based out of one real time implemenation need:

Step 1:Oracle System
Lets say you have Oracle installtion ready at your side.

2. EDI gateway : Use can use oracle provides the EDI Gateway, which allows the user to interact with a GUI or command prompt. The gateway extracts the relevant data from the database for each transaction.

How it works …take a example of PO
—————–
if you want to create an Outbound Purchase Order, 850, the gateway would pull information such as part numbers, quantity, price, and any relevant information in regards to the trading partner. All code conversions and trading partner definitions are stored in the gateway. At this stage, you will need to contact your trading partners and decide on standards, codes and any other relevant information.

3. Step 3:

Once the Purchase Order is created, it is extracted to the translator. There are several options when choosing a translator provider.

There are different Options you can chosse for Translator , few are Sterling, Harbinger etc

Most of Customer who usses Oracle , Sterling’s Gentran is prefrered one as these are the products from Patners and have seamless integration.

What the translator do:

The translator provides the API mapping and converts the extracted EDI transaction into an accepted standard.Now a days depends upon what format is required, it may be ASCI , XML or any other standard format.

an 810 is an inbound invoice and an 830 is an outbound planning forecast. After the translator stamps the transaction with a standard, the file is ready to be sent to the trading partner.

There are other option for transmitting the files , one of such example are point-to-point either over the Internet via ftp.

For this you can use any ftp software package can be used.

2-3 years back there was other options where companies utlizes store-and-forward mechnism via VAN, that is value added network.

In that case VAN acts very similar way that post office of postal department work for the trading partners. The VAN receives the file and holds it until the trading partner dials in to the VAN and asks for any files. A VAN provides more security than the Internet
