Data Element

The basic units of information in the EDI standards containing a set of values that represent a singular fact. They may be single character codes, literal descriptions or numeric values. EXAMPLE: "PURCHASE-ORDER-NUMBER."

Data Element Delimiter

The single character delimiter follows the segment identifier and each data element in a segment except the last.

Data Element Length

This is the range, minimum to maximum, or the number of character positions available to represent the value of the data element. A data element may be of variable length with the range from minimum to maximum, or it may be of fixed length in which the minimum is equal to the maximum.

Data Element Reference Number

Unique identifier assigned to each data element.

Data Element Requirement Designator

A code defining the need for a data element value to appear in the segment if the segment is transmitted. The codes are Mandatory (M), Optional (O) or Conditional ©.

Data Element Type

A data element may be one of six types: numeric, decimal, identifier, string, date or time.

Delimiters

The delimiters consist of two levels of separators and a terminator. The delimiters are an integral part of the transferred data stream. Delimiters are specified in the interchange header and may not be used in a data element value elsewhere in the interchange.

DISA

Segment

Logically grouped data, usually an electronic representation of a "line" on a printed business document. A data segment consists of a segment identifier, one or more data elements, each preceded by an element separator and ending with a segment terminator (X12.6).

Segment Directory

X12.22 provides the purposes and formats of the segments used in the construction of transaction sets. The directory lists each segment by name, purpose, identifier, the contained data elements in the specified order and the requirement designator for each data element.

Segment Identifier

A unique identifier for a segment composed of a combination of two or three uppercase letters and digits. The segment identifier occupies the first character positions of the segment. The segment identifier is not a data element.

Segment Terminator

A unique character appearing at the end of a segment to indicate the termination of the segment.
