Documentation Tools
The IDoc interface is an open interface, which means that the structure and use of the IDoc types is transparent. To allow for this, the IDoc Interface provides tools which display the documentation in various formats. You can choose between the technical view (such as field lengths or release information) and the application view (such as the meaning of the actual application data in the segment).
Another advantage of the documentation tools is that they can also format information for automatic processing. In this way, an EDI subsystem, for example, can be supplied with information about a new IDoc type so that the IDoc type can be processed correctly in future.

format is used for output to the screen.
