Hi @priyanka.mundargi,

The RDMFieldDictionary file represents the complete list of fields you will encounter throughout the different asset classes within Elektron. The structure of the file defines key attributes such as the FID (Field ID), Acronym (Name of the field), the type etc. The file structure is used by multiple products consuming Elektron data.

The enumtype.def field is specifically reserved for those fields that are defined within the RDMFieldDictionary as "ENUMERATED", for example:

CURRENCY   "CURRENCY"  15  NULL  ENUMERATED    5 ( 3 )  ENUM             2
! The currency in which the instrument is quoted.

For ENUMERATED fields, you will find the possible enumerated values associated with the specified field within the enumtype.def file. For example for the CURRENCY FID (15):

! ACRONYM    FID
! -------    ---
!
CURRENCY      15
CURRENCY_2  1084
CURRENCY_3  1085
...

! VALUE      DISPLAY   MEANING
! -----      -------   -------
      0        "   "   Not allocated
      4        "AFA"   Afghanistan afghani (from 1925 until 2003)
      8        "ALL"   Albanian lek

The value populated within CURRENCY will be represented as the values you see above. Many FIDs are ENUMERATED types and share the same definition - as you see above.

Hope this helps.
