Client is facing the issue in running the Report client has access for the RIC .FTAS

from datetime import datetime as dt
import pandas as pd
import eikon as ek

app_key='c5468339768f4efd92d04b15e44ae3b62dab8f22'
ek.set_app_key(app_key)
index_code='.FTAS'
initial_date = pd.Timestamp(2025,7,18)

fields = ['TR.IndexJLConstituentChangeDate', 'TR.IndexJLConstituentRIC.change', 'TR.IndexJLConstituentRIC']
parameters = {'SDate': '0D', 'EDate': dt.strftime(pd.Timestamp(initial_date),'%d-%b-%Y'), 'IC': 'B'}

getting the joiners and leavers information

lj, err = ek.get_data(index_code, fields, parameters)

@Uday_PK, what is the issue?

Please ask the user to find out the applicable fields from the Data Item Browser for this instrument. These fields are not applicable to the index instrument provided.

Huma

Gurpreet,

The user is using the below script and the fields are available in DIB. Also the User is trying to pull the Historical constituents for .FTAS

import refinitiv.data as rd
from datetime import datetime as dt
import pandas as pd

rd.open_session()

universe = ['0#.FTAS']
initial_date = pd.Timestamp(2025,7,23)
fields = ['TR.IndexJLConstituentChangeDate', 'TR.IndexJLConstituentRIC.change', 'TR.IndexJLConstituentRIC']
parameters = {'SDate': '0D', 'EDate': dt.strftime(pd.Timestamp(initial_date),'%d-%b-%Y'), 'IC': 'B'}

df = rd.get_data(universe, fields, parameters)

print(df)

Even I tried to rebuilt it but getting the same Error as

refinitiv.data._errors.RDError: Error code -1 | Unable to resolve all requested identifiers in ['0#.FTAS'].

Secondly , Also wanted to know is the below Alert something related to the above concern.

Huma,

I don't see any data for the fields - 'TR.IndexJLConstituentChangeDate', 'TR.IndexJLConstituentRIC.change', 'TR.IndexJLConstituentRIC' in the Data Item Browser - neither for index, nor for the chain RIC. For content clarifications, please raise a ticket at LSEG MyAccount. We can only help with technical API related issues.

@Huma

Please contact the helpdesk to request the working @RDP .Data Excel formula. Once you have it, kindly share it with us so we can convert it into Python code.

Uday_PK

@Jirapongse Please find the below RDP Excel formula.

=@RDP .Data(".FTAS","TR.IndexJLConstituentChangeDate;TR.IndexJLConstituentRIC","CH=Fd RH=IN")

Jirapongse

@Uday_PK

Thank you so much.

The Python code looks like this:

ld.get_data(
    universe = ['.FTAS'],
    fields = ['TR.IndexJLConstituentChangeDate','TR.IndexJLConstituentRIC'])

I am using the get_data method in the LSEG Data Library for Python.

Uday_PK

@Jirapongse ,

Thanks for Providing an update.

Can you please create an Python script for the below formula.

=@RDP .Data(".FTAS","TR.IndexJLConstituentChangeDate;TR.IndexJLConstituentRIC;TR.IndexJLConstituentituentChange","SDate=2025-07-25 EDate=2000-01-01 CH=Fd RH=IN")

Jirapongse

The Python code is:

ld.get_data(
    universe = ['.FTAS'],
    fields = ['TR.IndexJLConstituentChangeDate','TR.IndexJLConstituentRIC','TR.IndexJLConstituentituentChange'],
    parameters = {
        'SDate':'2025-07-05',
        'EDate':'2000-01-01'
    })
