Which four statements are true about defining Global Segments for a Descriptive flexfield?

Which four statements are true about defining Global Segments for a Descriptive flexfield?
(Choose four.)

A.
Global Segments should be planned first.

B.
Some Descriptive flexfields use only Global Segments.

C.
Descriptive flexfields cannot existonly along with Global Segments.

D.
Global Segments are segments that appear regardless of the context.

E.
Global Segments can be planned anytime while defining a Descriptive flexfield.

F.
The columns that are used for Global Segments cannot hold context-sensitive segments.

Explanation:
A (not E): When you define your descriptive flexfield, you should always define your
global segments first to ensure that your global segment can “reserve” that column for all
structures. Then, you define your context-sensitive segments using the remaining columns.
D: A global segment is a segment that always appears in the descriptive flexfield pop-up window
(or page, for HTML-based applications), regardless of context (any other information in your form
or page).
F:A global segment uses the same column for all rows in the table. A context-sensitive segment
for one structure uses a given column, but a context-sensitive segment in a different structure can
“reuse” that same column.
Note:
Descriptive flexfields have two different types of segments, global and context-sensitive, that you

can decide to use in a descriptive flexfield structure.
A global segment is a segment that always appears in the descriptive flexfield pop-up window (or
page, for HTML-based applications), regardless of context (any other information in your form or
page). A context-sensitive segment is a segment that may or may not appear depending upon
what other information is present in your form.
