Electronic Data Interchange is fully automatedBut until it works, it is a people business

SAP Project Manager“We must deliver on

time and budget”

SAP Consultant“I must adhere to the

business blue print and get the customizing right”

ABAP programmer“*@%#& them and their

constantly changing requirements”

SAP Basis“The instance is too small,I told them a million times”

Car manufacturer“Please call global service

helpdesk for further assistance”

Customer“We must go live on xyz

by all means”

Supplier“We not have time

for EDI now, please comeback in 6 months”

EDI service provider“SAP team, customer,

suppliers and OEMs, please provide commitment”

Goods identification and advanced shipping notifications

7

„Information about the transported goods is as important as the goods themselves“

-- Edward Guilbert

What is Electronic Data Interchange exactly?

• Not a „single“ technology – rather a concept

• The exchange of structured electronic documents between software systems of different companies with minimal human intervention.

The three main requirements of electronic data interchange

Unique identification of exchanged products and services as well as the participating partners

Unique representation of exchanged information

Exchange procotol, which guarantees delivery of electronic documents

10

Identification by brandMainly for customers and marketing purposes

11

Machine processing without unique identification. How many companies do you see?

Identification numbers to the rescueWe simply take SAP debtor or creditor numbers

13

Do not do that. Ever.

14

Necessity of unique identification

• Companies

• Products and services• Transport units

• EDI addresses

Solution

• Use of a common code scheme, which is maintained by a central administration body

• Prevents use of duplicate codes and guarantees global uniqueness

15

Where to take these “unique” numbers from?

16

Bilateral agreement between partners

• Global uniqueness• Very common in retail• Unique identification of partners (GLN),

products (GTIN), pallets (SSCC), etc.

• Global uniqueness• Unique identification of partners only (DUNS no.)

• No global uniqueness• Often used in industry (e.g., BMW-AG,

JLR, etc.)• Customer/supplier material numbers

Global Location Numbers (GLN)Unique identification of business partners and EDI mailboxes

17

N1 N2 N3 N4 N5 N6 N7 N8 N9 N10 N11 N12 N13

GS1 company prefix(7 – 9 digits)

location reference check digit

Structure

Example

GLN: 9 0 1 2 3 4 5 1 0 0 0 0 1

Tired?

20166.062 billion cans sold

GTIN – Global Trade Item Number

• GS1 number for the unique identification of trade items

• A GTIN has 8/12/13/14 digits

• GTIN is based on the GLN of a company

• GTINs are exchanged using master data exchange concepts (e.g., GDSN - Global Data Synchronization Network)

19

SSCC – Serial Shipping Container Code

Unique identification of transport units

Your nice internal data structures?

23

Unambiguous representation of exchanged information is an important prerequisite for EDI

Application-to-application communication requires a standardized exchange format, which sender and recipient understand

XML-Standards

• Became increasingly popular by mid/end of the nineties of the last century

• Distinction between markup and content• Larger memory footprint than delimiter based or fixed-length formats

• Please never say “it is human-readable”

Routing of EDI messages

Each EDI message must be able to answer the following four questions:

• Who are you?• Where do you come from?

• Where do you want to go?

• Are you a test message?

Additional questions• What is your unique ID?

• When have you been created?

36

Data exchange

37

IBM 360 in action at Volkswagen

Data transport today using dedicated protocols

• AS2

• SFTP, FTPS

• OFTP2

• OFTP1 (not recommended, as ISDN will soon be switched off)

• X.400 (can be quite costly)

• RESTful Web Services• Usually for the last mile between ERP and service provider, e.g., Ariba, ecosio, etc.

• SOAP/WSDL• Quite verbose and rigid – cf. WS-Death Star

• SMTP• Only when sender authenticates at the SMTP

• VAN• Old term for dedicated EDI networks. Some still exists, e.g., ANXeBusiness, ENX, JNX, etc.

38

Data transport – usually a four corner model is used

• The originator must re-key (= the SAP)

• Do not re-key in the mapping on the service provider’s side (maintenance nightmare)

Wrap up

• EDI is a prerequisite for efficient inter-organizational processes

• Large enterprises and medium-sized companies need EDI to run their business

• SMEs must comply with the EDI requirements

• However, they may benefit from EDI as well

• EDI converter

• Four corner-model communication• SAP may serve as target/source for EDI processes

• EDI in SAP is not turn-key – some configuration is always necessary
