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.

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.

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.

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.

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.
