API for Eikon vs Workspace Data

Hello @Jayson

Thank you for the information. I checked the given source code. The client's code queries the fields from internal database, so I cannot test the completed fields set the same as client.

Please confirm if my replication results (see below) are the same as the client, then I will contact the library team to check this issue.

I am testing with https://developers.lseg.com/en/api-catalog/eikon/eikon-data-api and Data Library version 1 (RD)/Data Library version 2 (LD) using the following query and field:

query_string1 = (

    'SCREEN('

    'U(IN(DEALS)), '  # Base filter for deals

    'IN(TR.MnAStatus,"P","C"), '  # MnA Status filter: Pending or Completed

    'IN(TR.MnAType,"1"), '  # MnA Type filter: Specific type: Disclosed Value

    'IN(TR.MnATargetNation,"US") OR IN(TR.MnAAcquirorNation,"US"), '  # Nation filter: Target or Acquiror is US

    'BETWEEN(TR.MnAAnnDate,20100101,20241128), '  # Date range filter: 2010-01-01 to 2024-11-22

    'TR.MnARankValueIncNetDebt(Scale=9)>=1, '  # Rank value filter: >= 1 (scaled to billions)

    'NOT_IN(TR.MnAREITType,"EQ","HY","MO","UN"), '  # REIT Type exclusion: Exclude specific REIT types

    'TR.MnAHasDisclosedFee==true, '  # Disclosed fee filter: Include only deals with disclosed fees

    'NOT_IN(TR.MnATargetFinAdvisorLong,"5422M","33722M","48279M","49326M","50255M","53043M","53456M","61457M") AND '

    'NOT_IN(TR.MnAAcquirorFinAdvisorLong,"5422M","33722M","48279M","49326M","50255M","53043M","53456M","61457M")' # Exclude PJT

    ')'

)



fields = ['TR.MNARATIOOFENTERPRISEVALUEATEFFDATETOEBIT']

Eikon Data API:

import eikon as ek


ek.set_app_key('My App Key')




deal_ek, err = ek.get_data(

                instruments = query_string1,

                fields = fields,

                parameters = {"Curn": "USD"},

                field_name=True

            )


deal_ek.head()




deal_ek.dtypes

Data Library version 1:

import refinitiv.data as rd


rd.open_session()


deal_rd = rd.get_data(

	universe=query_string1,

    fields=fields,

    parameters={"Curn": "USD"},

    use_field_names_in_headers=True

)


deal_rd.head()


deal_rd.dtypes

Note: Data Library version 2 (LD) returns the same result as version 1

Hello @Jayson

I have contacted the Data Library team. The team says that rd.session.get_default().config.set_param("apis.data.datagrid.underlying-platform","rdp") statement changes underlying platform to get the data in the right format which takes times + requesting SCREEN() is also a time consuming, so the timeout can be occurred.

The team suggests the client increases HTTP request timeout to avoid the issue.
