Class ID

Class ID is the unique identifier or description of the class. 

If segments are setup for the class field in Key Segment Definition, the individual segments will display in the Class Edit Window and the Class ID will be populated with each segment value and separated with a  "-".  

If a segment is to be validated, a drop down list will be available that contains the valid values entered for the segment in Key Segment Validation.

See the Classes with Key Segments screen.
