    What is edi What is edi Document Transcript

    • What is EDIEDI stands for “Electronic Data Interchange.” The practice involves using computertechnology to exchange information – or data – electronically between two organizations,called “Trading Partners.” Technically, EDI is a set of standards that define common formatsfor the information so it can be exchanged in this way.Processes that used to be completed manually with paper have been replaced with aninvisible, electronic flow of formatted data. EDI has replaced paper forms of manydocuments, including invoices, bills of lading, advance shipping notifications, studenttranscripts, healthcare claims and many others.Many businesses, government agencies and other organizations use EDI every day in theregular course of business. That’s because EDI makes doing business together a moreautomated and efficient process. Plus, digital technology can help ensure greater informationsecurity compared to paper documents.How EDI Works – the ProcessFor the most part, EDI-based transactions are really the same as their manual, papercounterparts. The difference is that the EDI transactions are sent and received electronically,as packets of data formatted according to EDI standards.There are effectively three major processes involved in the exchange of EDI data: mapping,translation and communications. Mapping involves transforming an EDI document into another format (such as XML, a flat file, a delimited file, etc.) or vice versa. Mapping is essential for proper system integration. Translation is the process of accepting inbound EDI data, or preparing an outbound file for transmission. Communications refers to the transmission of the EDI transaction. This can be done indirectly, through an external clearinghouse or VAN (“Value Added Network”) or direct via AS2 using EDI software, a web-based EDI tool or outsourcing with an EDI service provider.Why You Need EDI – the BenefitsFor many companies, EDI is really not a choice. It may be a requirement of doing businesswith larger organizations, including big retailers, manufacturers and government agencies.Once you are communicating via EDI, the door is open to maximizing its value to yourbusiness. By integrating your EDI workflow with your back-end business or accountingsystem, you can streamline the entire process of how information flows through yourorganization. The benefits can be tremendous, including: Lower costs – By reducing the manual keying of data, handling of documents and other processes, you can potentially reduce the costs of labor and paper, and reduce errors (and their associated costs).
    • Higher efficiency – Sending and receiving EDI data happens in seconds, and the information can be acted on immediately. This means time savings for you and your trading partners. Improved accuracy – You can reduce errors by using EDI because manual and duplicate entry is eliminated. Everything flows untouched, leaving a trail for easy future tracking. More supply chain visibility – With EDI, product sales data, product inventory status, demand forecasts and other metrics can be shared with suppliers and their suppliers. This allows for better inventory management and supports just-in-time delivery. Enhanced security – Thanks to numerous communications protocols addressing encryption and other security issues, critical business or personal data may be exchanged with higher levels of security via EDI than by any other means. Greater management information – Because EDI data is electronic data, you have a source of information to guide management decisions or to mine for further analysis.Ready to take advantage of the many benefits of EDI?

It provides a completeoverview of EDI…and it’s FREE.EDI Partner Profile ConfigurationA partner profile is defined for every business partner with whom you exchange businessdocuments. In EDI, a partner can be a customer, a vendor, a bank, or any entity with whichyour company does business.In ALE, a partner is a remote SAP system or legacy system with which you exchange data. Apartner profile specifies the various characteristics of data that you exchange with a businesspartner, the mode of operation, and an organization or person responsible for handling errorsfor that business partner.Its transaction code is WE20 and its Path is : From the Area menu of EDI, choose IDoc,Partner Profile.A partner profile has three views, which maintain different parameters for a partner.1.The General Parameters view. Values are stored in table EDPP1.2·The Outbound Parameters view. Values are stored in table EDP13, except for the Messagecontrol parameters, which are stored in table EDP12.3·The Inbound Parameters view. Values are stored in table EDP21.
    • The General ViewThe main Partner Profiles screen, shown in figure below, displays the general parametersview at the top of the right frame. The outbound and inbound views are also accessed fromthis screen; they appear below the general view fields.The General Parameters view contains very basic information about the partner, such aspartner number, partner type, partner status, and default individual to notify in case an erroroccurs.These partner attributes appear at the top of the main Partner Profiles screen and under thePost Processing: Permitted Agent and Classification tabs. The entries under the Telephony tabare generally not relevant to EDI or ALE. You enter this information only once for eachpartner, and these values are stored in table EDPP1.
    • We define the attributes in thegeneral parameters view like1.Partn. number: In EDI, the partner number can be a customer number, vendor number, orbank ID. In ALE, it is the logical name assigned to the partner SAP system or legacy system.The standard system validates the partner number against the customer master, vendor master,or bank master data, depending on the type of business partner.2·Partn. type: The partner type represents the type of your business partner. For example, inEDI it is customer (KU), vendor (LI), and bank (B). In ALE, it is the logical system(LS).(72.4)EDI Partner Profile Configuration part twoThis is in continuation with EDI Partner profile configuration part one. In the Post Processing:Permitted Agent tab, you define the individuals to be notified when an error occurs in IDocprocessing at a point where the system has identified the partner, but not the message type.The fields on this part of the general parameters view areTyp: This field identifies the workflow object type of the Agent to be notified in case of error(for example, US for user ID, S for position, or O for organization).Agent: This field indicates the workflow object (for example, user, position, or organizationalunit) used for notification. This object is notified when a corresponding outbound or inboundrecord is not found for a message that is being sent to or received from this business partner."Configuring Workflow," for details on how the system sends workflow notifications forerrors. For example, if a person with position ID 12345678 is responsible for handling errorsfor this business partner, the value of the various fields are S for Typ, 12345678 for Agent,and E for Lang.Lang : This field identifies the language in use for this agent.Avoid using a user ID in the Agent field. You should use more abstract object types, such as
    • position, job, or organizational unit. This approach saves you the headache of changing theentry when the user leaves the company or changes jobs. Compared to users, objects such aspositions, jobs, and organizational units tend to be more stable.On the Classification tab, we define the following:Partner Class : This field is for documentation only and has no intelligence behind it. Youuse this field to classify your partners. For example, if you want to classify automotivevendors versus railroad vendors, you can enter particular codes representing automotive orrailroad.Archv: This field is also for documentation purposes only. It indicates whether a partneragreement exists. Partner agreement is an EDI term for legal documents that define eachpartners responsibilities in a business relationship.Partner Status: This field makes a partner active or inactive. If a partner is deactivated, nodocuments are passed to it.If you maintain partner profiles in the production system, you can use the Partner Status fieldto indicate that a partner profile is under construction. After the partner profile is complete,you activate it to mark it ready for use.(72.8)Difference Between EDI and IDOCEDI is nothing but Electronic data interchange. SAP will support EDI through Intermediatedocuments (IDOCS).EDI (Electronic Document interchange) - EDI is the electronic exchange of businessdocuments between the computer systems of business partners, using a standard format over acommunication network.EDI is also called paperless exchange.Advantages:Reduced Data entry errorsReduced processing timeAvailabilty of data in electonic formReduced paperworkReduced CostReduced inventories and better planningStandard means of communicationsBetter business processEDI has two process1.

    • Explain to me about Idoc?IDoc (for intermediate document) is a standard data structure for electronic data interchange(EDI) between application programs written for the popular SAP business system or betweenan SAP application and an external program. IDocs serve as the vehicle for data transfer inSAPs Application Link Enabling (ALE) system.IDocs are used for asynchronous transactions: Each IDoc generated exists as a self-containedtext file that can then be transmitted to the requesting workstation without connecting to thecentral database.Another SAP mechanism, the Business Application Programming Interface (BAPI) is usedfor synchronous transactions.A large enterprises networked computing environment is likely to connect manygeographically distributed computers to the main database. These computers are likely to usedifferent hardware and/or operating system platforms. An IDoc encapsulates data so that itcan be exchanged between different systems without conversion from one format to another.IDoc types define different categories of data, such as purchase orders or invoices, which maythen be broken down into more specific categories called message types. Greater specificitymeans that an IDoc type is capable of storing only the data required for a particulartransaction, which increases efficiency and decreases resource demands.An IDoc can be generated at any point in a transaction process. For example, during ashipping transaction process, an IDoc may be generated that includes the data fields requiredto print a shipping manifest. After a user performs an SAP transaction, one or more IDocs aregenerated in the sending database and passed to the ALE communication layer. Thecommunicationlayer performs a Remote Function Call (RFC), using the port definition and RFC destinationspecified by the customer model.The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some externalsystem. *-- AshokALE, EDI & IDOCS in SAPALE, EDI & IDOCS in SAPWe will discuss a practical scenario here (specifically master data distribution using ALE ) .Here is what we will discuss in this article. If you want a more detailed explanation, pleasetake our professional training course on SAP ALE, EDI & IDOCS 1. What is ALE ? 2. What is EDI ? 3. Difference between ALE & ED 4. Customization involved in Master Data distribution using ALE.
    • Related TrainingsSAP TrainingSAP AccessSAP EDI TrainingWhat is ALE ?ALE stands for Application Link Enabling. Application Link Enabling is a very commontechnology used in SAP to transfer master and transactional data between different LogicalSystems. ALE is a proprietary SAP technology.What is EDI ?EDI stands for Electronic Data Interchange. EDI is a much older term and has been used inexistence much before SAP. EDI is a generic technology that has been standardized usingANSI and EDIFACT standards. EDI is a very standard Industry standard used for businesscommunication across partners.What is IDOC ?IDOC stands for Intermediary DOCument. IDOC is an SAP proprietary format for storingbusiness data that needs to be communicated across systems. When we mean systems, thiscould be between multiple systems ( Both SAP as well as non-SAP systems).What is the Difference between EDI & ALE ?ALE is used for distributing large volumes of similar data between different Logical systems.For example, distributing customer master data between two SAP systems is easily doneusing ALE. Similarly, when invoices from the core SAP system needs to be transferred to adifferent non-SAP invoice processing system, ALE is used.EDI is also used to communicate data between different logical systems. For ex., sending outinvoices, or order acknowledgements to customers is a perfect example to use EDI. Similarly,we could use EDI to receive inbound orders from customers.There is a general confusion that ALE is a technology to be used between different SAPsystems and EDI is the technology to be used between SAP and non-SAP systems. While thisis true statistically, in principle the difference is much more subtle.EDI is used to communicate with Partner Systems, while ALE is used to communicatebetween Logical Systems. Please do however observe that a Partner System could also be alogical system.CustomizationCustomization of ALE & EDI is pretty similar technically. Let’s concentrate on ALE first.
    • [SALE] -> This is the transaction code used for ALE configuration[WEDI] -> This is the transaction code used for ALE Development.We will be doing all the customization in an ECC 6.0 IDES system. So, please get access toone before following along.Logical System :In SAP, a logical system means a client in an SAP instance. A logical system is just a labelthat needs to be assigned to a client in SAP. Goto [SALE]->Basic Setting->Logical Systems.Here is where you define logical systems and assign them to a client.A shortcut to view the list of clients is [SCC4].Let’s pick client 800 (double click ) and as you can see, the name of the logical system isT90CLNT090. You can change it if you want to.Similarly, there is another client 810. Now, lets try to establish master data communicationbetween client 800 and client 810. (ie) between the two logical systems.If a new logical system needs to be defined, it can be defined here. Each logical system needsto be assigned to a client.
    • Configuration to be done on SENDER systemRFC ConnectionRFC stands for Remote Function Call.SAP mandates that the name of the RFC destinationshould be the same as the logical system. An RFC connection provides a level of abstractionover the actual connection details between 2 different systems. In this case the communicationshould happen between client 800 and client 810 on the same SAP instance. We are nowtrying to create an RFC connection for client 810 on 800. This would require connectiondetails ( IP Address ), client number and authentication details ( user id and password ). Whatwe are essentially doing is establishing a conduit to another system.In this example, we are trying to establish an RFC connection between two clients on thesame SAP instance. However, this procedure is same even if it is across different SAPinstances.As you can see, there are different types of RFC connection. Without confusion ourselvesfurther, lets just say, ABAP connections are used when the source and destination systems areSAP. TCP/IP connections are used when communicating with a non-SAP system.
    • Let’s try to create the RFC connection with the same name as the RFC destination –CUSTDEM810. ( In a standard SAP IDES system, this name could be different )The system automatically picks up the IP address if the host is on the same subnet.
    • Enter the user id and password to test the RFC connection.Cross Company CodeWhen transferring master data that has company code relevant data ( For example, theFinance view of the customer master data ), SAP mandates that we maintain a cross-companycode. This is more of an SAP hack and might be taken away in the future.Define a new cross-system company code say “GL2300″ -And follow further configuration to assign the company code to Chart of Accounts and actualcompany code.It is pretty self-explanatory.All of these functions can be handled in the menu path shown above. As discussed, these arejust labels and do not have any controls.Here is assigning cross-system company code GL2300 to company code 2300 and to INTchart of Accounts.
    • Distribution ModelA Distribution Model defines the following Sender Logical System Receiver Logical System Message Type ( logical Message type , Not the IDOC type )Goto [BD64], select the pencil button and click on “Create Model View”. Enter a technicalname and a short text.After generating the distribution model, goto Environment -> Generate Partner Profiles. Enterthe name of the target logical system.
    • The log of the partner profiles will be generated. Sometimes SAP does not do thisautomatically and we might have to create the partner profiles manually.If you go to [WE20] you can see that SAP has generated partner profiles for us automaticallybased on the previous step. (Select Partner Type LS ).
    • Pushing a Customer ThroughNow lets push a customer through. Goto [BD12] (Tools -> ALE -> Master Data Distribution -> Cross Application -> Customer )Enter a customer number, the output type ( DEBMAS in this case ). If you execute the systemnow, a master IDOC will be created and as many number of communication IDOCS will becreated as there are distribution models set for the output type. If you select the right logicaldestination, only 1 communication IDOC will be generated.
    • If you want to see the IDOC that has been processed, goto [WE02] and select the IDOCScreated for today and sort by date to get the latest IDOC. As we can see from the greensquare, the IDOC has been processed successfully. If in case the IDOC has failed, use [BD87]to re-process the IDOC.Now, in order to check the IDOC on the other logical system ( Client 810 in this case ) , logonto the client 810 and use [WE02] to look at the IDOCS in bound.
