Unable to resolve all requested fields in ['TR.SHARETYPE'].

Vikram_2910

To return to my previous problem, I realized that only part of the query worked. I can successfully extract the "GICS Sector" and the "GICS Industry Sector" from an ISIN using the fields "TR.GICSSector" and "TR.GICSIndustryGroup". However, I can’t extract the "Instrument Type" using the field you provided me: "TR.ShareType".

 

Here is my code (for one ISIN to simplify):

 

import lseg.data as ld

 

ld.open_session()

 

isin = ["IE00B4BNMY34"]

 

try:

    result = ld.get_data(

        universe=isin,

        fields=["TR.ShareType"]

    )

 

    print("\n=== Résultat brut de ld.get_data ===")

    print(result)

 

except Exception as e:

    print(f"\nErreur pendant la requête LSEG : {e}")

 

ld.close_session()

 

I get this error (which I have already encountered many times when trying to extract the type of instrument):

 

Erreur pendant la requête LSEG : Unable to resolve all requested fields in ['TR.SHARETYPE']. The formula must contain at least one field or function.

 

Do you have any idea to help me extract the type of instrument from an ISIN in Python? Is there a place where I can find documentation regarding field names (like "TR.ShareType" for example)?

@Vikram_2910 Thanks for your question - so you can find all fields that are available using the Data Item Browser app (type DIB into the launcher bar). In this case the field you requested in not spelt correctly:

ld.get_data(

universe=['IE00B4BNMY34'],

fields=['TR.SharesType']

)

I hope this can help.
