Descriptive flexfields have two different types of segments, global and context-sensitive . Descriptive flexfields provide customizable "expansion space" on your forms. You can use descriptive flexfields to track additional information, important and unique to your business, that would not otherwise be captured by the form. Descriptive flexfields can be context sensitive, where the information your application stores depends on other values your users enter in other parts of the form.A global segment is a segment that always appears in the descriptive flexfield pop–up window. A context–sensitive segment is a segment that may or may not appear depending upon what other information is present in your form. A descriptive flexfield uses columns that are added on to a database table. A descriptive flexfield requires one column for each possible segment and one additional column in which to store structure information (that is, the context value).
