Why are there fields visible in data item browser that are not accessible via Eikon Data AP?

@javan.graham, You can filter the fields in data item browser, by typing in the RIC code for the item you are interested in, in which case only the applicable fields are shown.

These fields are relevant to equities and can be pulled for equity quotes like:

>>> df, err = ek.get_data(['GOOG.O','MSFT.O', 'FB.O'], ['CF_LAST', 'CF_BID', 'TRADE_DATE'])
>>> df
  Instrument    CF_LAST   CF_BID  TRADE_DATE
0     GOOG.O  1228.8400  1228.60  2019-07-30
1     MSFT.O   140.8435   140.84  2019-07-30
2       FB.O   196.4850   196.47  2019-07-30

Hi Javan, the “CF_” field is “Consolidate/Common” field generated by application
such TRKD and Eikon. The applications use their own logic to map
the existing field to the "CF_" field, and these are only available for RIC's. Thanks.
