A basic IDOC type has the following characteristics:

List of permitted segments: The segments make up the IDOC structure.

Hierarchy of segments : The hierarchy of segments specifies the physical sequence and

any parent - child relationship in the segments.

Mandatory Vs Optional Segments : When used in the IDOC type, each segment has

an attribute that defines whether the segment is option or mandatory.

Minimum/Maximum range for each segment: It defines the maximum and minimum

number of timesa data record corresponding to a segment cn exist in an IDOC.
