Segment extraction format
The Segment extraction format extracts a subsection of an output item. It can be used, for example, to extract only the numeric values from an alphanumeric string such as ID235ZA.
Note: Segments are reserved for alphanumeric fields. Segment functionality cannot be applied to numeric reference fields, where
the field is referential.
Segments are specified by offset and length.
For example, to extract the numeric string 235 from the alphanumeric string ID235ZA , specify an offset of 2 and a length of 3.
The offset of 2 specifies that the first two characters of the string are ignored.
The length of 3 specifies that the extracted string is three characters long.
