Fund data points not pulling in through Python

mm23

Hello,

It seems fund data points such as 'TR.FundCompany' or 'TR.FundType' or 'TR.Fund1YearPerf' are not pulling in through Python (I use Jupyter Notebook).

Here is an example code:

import lseg.data as ld
ld.open_session()
df = ld.get_data(universe = ['LP65011527'], fields = [         'TR.FundCompany','TR.FundType','TR.Fund1YearPerf','TR.CommonName'] )
display(df)

Only the data point TR.CommonName shows correctly, the rest show <NA>.

LSEG helpdesk suggested I try this in CODEBOOK within Workspace and the code produced correct results. May I ask if this is a bug or a feature?

Kind regards

Thank you for reaching out to us.

Are you using the Platform session (platform.rdp or platform.ldp)?

I tested it on the platform session and got the following response.

[2026-01-16T14:55:13.009893+07:00] - [sessions.platform.ldp.0] - [DEBUG] - [9644 - MainThread] - [http_service] - [request] - HTTP Response id 4
status_code = 200
text = {"links":{"count":1},"variability":"","universe":[{"Instrument":"LP65011527","Company Common Name":"Danske Invest Compass Liquidity G","Organization PermID":null,"Reporting Currency":"Failed to resolve identifier(s)."}],"data":[["LP65011527",null,null,null,"Danske Invest Compass Liquidity G"]],"messages":{"codes":[[-1,221,221,221,-1]],"descriptions":[{"code":-1,"description":"ok"},{"code":221,"description":"The access to field(s) denied."}]},"headers":[{"name":"instrument","title":"Instrument","type":"string","description":"The requested Instrument as defined by the user."},{"name":"TR.FundCompany","title":"Fund Company","type":"string","description":"Fund Company."},{"name":"TR.FundType","title":"Fund Type","type":"string","description":"Fund Type."},{"name":"TR.Fund1YearPerf","title":"1 Year Performance to Last Month End","type":"string","description":"Takes into account not only the capital gains of an investment but also the income yield from dividends or interest payments. The calculation of total return is based on the assumption that interest payments or dividends are immediately reinvested. Value is measured for last year."},{"name":"TR.CommonName","title":"Company Common Name","type":"string","description":"Where available provides the name of the organization most commonly used. Provides primary share class name for funds."}]}

This could be a permission issue. As far as I know, some data may be only accessible through the desktop session.

You may need to contact your LSEG account team or sales team to verify this.

You can see the error code by enabling the debug before opening a session.

config = ld.get_config()

config.set_param("logs.transports.file.enabled", True)

config.set_param("logs.transports.file.name", "lseg-data-lib.log")

config.set_param("logs.level", "debug")


ld.open_session(…)

Then, the lseg-data-lib.log file will be created.
