Idoc types in sap
Both serve the purpose of data exchange and automation in computer systems, but the IDoc-Technology takes a different approach. While XML allows having some metadata about the document itself, an IDoc is obliged to have information at its header like its creator, creation time etc. While XML has a tag-like tree structure containing data and meta-data, IDocs use a table with the data and meta-data. IDocs also have a session that explains all the processes which the document passed or will pass, allowing one to debug and trace the status of the document.
Different IDoc types are available to handle different types of messages. IDoc technology offers many tools for automation, monitoring and error handling. When this order cannot be created because of an application error for example: The price per piece is lower than allowed for this materialthen the administrator on the vendor's system sees this IDoc among the erroneous ones and can solve the situation.
If the error is in the master data at the vendor's system, he can correct them and order the IDoc to be processed again. Because of the flexibility and transparency of IDoc technology, some non-SAP technologies use them as well.
The IDoc itself is a structured Text-File, that means IDocs can be used on all platforms, there is no need to translate binary data. Each record is identified by the name of the record. The load data is stored in a byte long container. The following transactions can be used to create and process IDocs. The list does not include any transaction required for the development of new IDoc types.
Please note that you get a comprehensive list of available transactions by using area menu WEDI. Messages can be printed, sent or transferred into IDocs. SAP uses this for many applications e. Purchase Orders PO. Unfortunately, the provided functionality is very basic; therefore, most customers are forced to create their own custom solution.

The basic idea behind an IDoc was introduced in a previous blog post. Unfortunately, the term IDoc is not always used consistently. In this post we want to define the following five IDoc terms and take a closer look at their specific concepts. In computer science an instance is an occurrence of an object during the runtime of a program.
An IDoc instance is of no difference here — it is a concrete occurrence of a document object. IDocs are stored internally in a persistent manner in the database in SAP, whereby the following tables are filled:.
Usually the user will not access the database tables directly but use the appropriate SAP transaction, like BD The following image shows IDoc Nr.
IDoc Instance in transaction BD To exchange an IDoc between SAP and an external system, an IDoc instance will be serialised to an export format and written into a physical file. IDoc XML-file. The following image shows the stored IDoc in transaction BD IDoc tree in transaction BD The message type describes the type of business document in an SAP system — e.
A message type can support different use cases. The message type ORDERS for example can be used for an outbound order sent to a supplier or an inbound order received from a customer.
The logical message type defines which application logic is being applied to the IDoc in the SAP system.
Thus, the logical message type provides the connection between the structure of the information and the application logic. The structure of the logical message type is further described by the IDoc basic type, which we will present in the next section. The IDoc basic type provides the structure for the logical message type.
"IDoc Basics: IDoc Basic Type and IDoc Message Type"
The following image shows the structure of IDoc Nr. IDoc structure in transaction WE The IDoc basic type can manifest itself in multiple logical message types. To get a list of all basic types and their logical message types, one may start a query via the following three tables. IDoc tables in QuickViewer. An IDoc extension type is an IDoc basic type with one or multiple additional segments. Book a Demo Philipp Liegl. Follow the author. Back To Overview.

In other words, an IDOC is like a data file with a specified format which is exchanged between 2 systems which know how to interpret that data. Every IDOC has a unique number within a client. In a case of any conflict in data size, it adopts one with greater length. IDOCs are independent of the direction of data exchange e.
Data is stored in character format instead of binary format. Structure of an IDOC The I doc structure consists of 3 parts - The administration part Control Record - which has the type of idoc, message type, the current status, the sender, receiver etc. This is referred to as the Control record.
The application data Data Record - Which contains the data. The Status information Status Record - These give you information about the various stages the idoc has passed through. Direction '1' indicates outbound, '2' indicates inbound. It contains data like the idoc number, name and number of the segment in the idoc, the hierarchy and the data The actual data is stored as a string in a field called SDATA, which is a char long field.
Segments are reusable components. For each segment SAP creates Segment Type version independent Segment Definition version dependent Segment Documentation The last 3 characters is the version of the segment Definitions keep changing as per the version but the segment type remains the same. In case you want to add more data to these restricted basic type you may use an extension type.
Most of the times you will NOT use extension. Orders, orders responses, invoices etc An idoc type can be associated with many message types Also, a message type can be associated with different idoc types. Partner Profiles A partner is defined as a business partner with whom you conduct business and exchange documents In the partner profile of a partner that we exchange Idocs with, we maintain the parameters that are necessary for exchanging the data.
The transaction used is WE Port The port defines the technical characteristics of the connection between your SAP system and the other system you want to transfer data with subsystem. The port defines the medium in which data is exchanged between the 2 systems. There are different types of ports. When using file port you can specify the directory where the IDOC file should be placed.ALE Objectives - ALE incorporates controlled exchange of data messages ensuring data consistency across loosely coupled applications.
ALE comprises of three layers. Each application is self-sufficient. The use of self-sufficient system implies a certain measure of data redundancy. Hence data has to be both distributed and synchronized. Message type gives the meaning of the IDOC. The messages exchanged between systems are of various message types. The message type depends on the data contained and the process involved.
The IDoc type indicates the SAP format that is to be used to interpret the data of a business transaction. Inbound as well as outbound interfaces use process code but for different purposes. How to trace the IDocs of the Receiving system from the Sending system? Message control is a mechanism by which documents are output based on a selection criteria and requirements. Message control determines the type of document, its timing, number, and the medium. NAST table stores output records. The conditions selection criteria and requirements for creating an output message are stored in condition tables.
Search mechanisms are used through access sequences, output processes, and requirements to determine whether an application document qualifies for output.

Where the IDOC information gets stored?Although we should always try to reuse iDoc Message Types and iDoc Types provided with standard SAP content, there could be scenarios where you need to create a completly new Message Type and iDoc type with your own custom processing logic.
Using Segment Editor configure the fields of each segment. Set the field names and assign a data type for each field. These two settings correspond to maximum number of occurrences and minimum number of occurrences of the iDoc segment. Notice, you also have to set the release version of your SAP system with the configuration.
Inbound iDoc function modules should be in a certain format. That is, all inbound iDoc processing function modules have the same signature import, export, tables and changing parameters. Find any standard inbound iDoc processing Function Module using transaction we57 and copy it to a custom Z function module in transaction se Create Partner Profile in transaction we20 with the same name of the Logical System we had registered in Step 1.
Then assign the custom Z process code created in previous steps. From the early days, I had a passion for coding, software development, and everything tech-related.

Other IDoc types are customer extensions. In these cases, a basic type is combined with an extension which is created by the customer, according to certain rules. Unlike customer extensionsthese extended. Messages of the same kind belong to the same message type. The Output type - An output type defines the characteristics and attributes of the output.
Generally used for Master Data transfer and as such depending upon the requirement can have different interfaces. The programs have a selection screen which has select options to select the objects, and parameters for specifying the recipient Logical System and the Message Type. Data is selected based on the specified objects from the tables.
The usual way of doing that is to define a batch-run job with transaction SM This job has to be set for periodic processing and start a program that triggers the IDoc re-sending. The only requirement for this program are two steps:. Basic IDoc type defines the structure and format of the business document that is to be exchanged between two systems.
Segments form the basic building blocks of an IDoc type and are used to store the actual datta. A segment type is the name of a segment and is independent of the SAP elease.

How to Create and Configure Custom iDoc Type in SAP
IDoc is an SAP object that carries data of a business transaction from one system to another in the form of electronic message. IDoc is an acronym for I ntermediate Doc ument. ANSI X12 describes business document as transactions and each transaction is represented by three digit number e. Each basic type describes standard IDoc segments, format of data fields and their size. Basic Type also defines number of segments and fields in an IDoc.
All the fields that are necessary for transmission of message for a particular business transaction are mapped in different segments. It also defines the structure and relationship of IDoc segments along with mandatory and optional segments.
Basic Idoc Type & message type
Basic type contains all the standard fields that are necessary for carrying out a business transaction. However, if any additional values are to be sent to the partner then we can make use of the IDoc Extension feature.
IDoc extension is extension of basic type and contains additional custom IDoc segments and fields that are not available in standard basic type. IDoc segments contain the actual data that is sent to or received from a partner.
These segments contain the actual values that are sent as part of IDoc transmission. IDoc segment is termed as Parent segment if it contains its own segments. The dependent segments are called as child segments. IDocs sent outside the system are termed as Outbound IDocs and the ones that are received into the system, are called as Inbound IDocs.
This signifies the direction is which information is sent and is similar to terminology used in mails. If information is sent outside the system then the direction is outbox when it is received into the system then direction is inbox. Partner is the Business Partner with which the exchange of information is to take place using IDoc. It can be a vendor or customer or any other system. IDoc processing involves transmission or receipt of document in the form of a message, each of which represents a document in SAP.
Message type is associated with Basic IDoc Type Basic Type and defines the kind of data or document that is exchanged with the partner. The process code contains the details of the Function Module that are used for IDoc processing. Message Type can be linked to the Process code. IDoc Port contains the information about the way data is sent between the source or target system. The type of port defines the information contained within the port.
Partner profile must be maintained for all the business partners to whom we want to send or receive the IDocs. Double clicking on the Partner will show the following screen:. Partner profile contains parameters for Inbound and Outbound processing of IDocs. Basic Type and extension. This contains application for which IDoc will be created e. Standard function modules are provided by SAP for this conversion however these can also be customized as per business needs.
Change Message Indicator indicates whether the IDoc is sentas a notification of change.
