Understanding the IDoc schema

The RSEIDOC3 report is composed of a packet container that can hold one or more IDocs. Therefore, the schema generated represents the contents. Each IDoc contains a control record, many data records, and some status records. Each IDoc consists of, and its sequence and structure are dictated by, the sequence and structure of segments in a particular kind of IDoc.

The IDoc structure is either ALE or EDI and schemas are generated for each format appropriately.

The attributes of a schema correlate directly to the IDoc metadata report. The IDoc fields correspond to items in a type. For example, the field name generates the item name and the text generates the item description. IDoc data is character-based and only the text or item description is language-dependent.

The schemas generated for either ALE or EDI contain types that are identically defined named Packet, IDoc, Group_number, Field, and Control Record. However, there are differences in how the segments are defined for the two different formats. A schema generated for ALE does not contain a Status Record type.
