All I wanted was DFF names and segments
I updated on OAUG email and got the below query which is somewhat useful.
--------------------------
SELECT dff.descriptive_flexfield_name,
dff.application_table_name,
app.application_short_name app,
u.descriptive_flex_context_code,
u.application_column_name,
u.end_user_column_name
FROM fnd_descr_flex_column_usages u,
fnd_descriptive_flexs dff,
fnd_application app
WHERE u.descriptive_flexfield_name NOT LIKE '$SRS$.%'
AND dff.descriptive_flexfield_name = u.descriptive_flexfield_name
AND app.application_id = dff.table_application_id
--AND dff.application_table_name = 'OE_ORDER_HEADERS_ALL'
--and u.descriptive_flexfield_name = 'RA_ADDRESSES_HZ'
ORDER BY app.application_short_name,
descriptive_flexfield_name,
descriptive_flex_context_code,
TO_NUMBER (REGEXP_REPLACE (u.application_column_name,
'[^0-9]'))
