How to get historical holdings and allocation data for funds?

How to get monthly or quarterly changes in a fund holdings, sector and country allocations? With the below code I'm only able to get the recent holdings and not the historical holdings.

Python

column_fields = [
    "TR.FundHoldingRIC",
    "TR.FundHoldingName",
    "TR.FundPercentageOfFundAssets",
]
refinitiv_data, err = ek.get_data(["SPY"], column_fields, date_paremters)
refinitiv_data

How to get the same historical weights for the below allocations?

Asset allocation -> ["TR.FundAssetAllocation", "TR.FundAllocationName"]

Country allocation -> ["TR.FundCountryAllocation", "TR.FundAllocationName"]

Sector allocation -> ["TR.FundIndustrySectorAllocation", "TR.FundAllocationName"]

Hi @BlackBird, I do not think the Eikon data API for Lipper (i.e. field name starts with "TR.Fund") can provide historical data currently. Because I do not see date parameters for these fields from Data Item Browser.

I know the RDP Funds API can can provide that.

However, if you only interested in ETFs, I am aware the constituent data is available from the Refinitiv's exchange data (not from Lipper I believe). Below is a sample code you can try. The sample is getting the data as of the month-end date 2 months ago. You can put in the exact date if you want, and I think they got daily data for most of ETFs. I am not sure if you can specify a date range. Also, I do not think the "allocations" data is available from Exchange data set, as allocations is likely only available from Lipper database.

df, err = ek.get_data(
    instruments = ['SPY'],
    fields = [
        'TR.ETPConstituentRIC',
        'TR.ETPConstituentName',
        'TR.ETPConstituentWeightPercent',
        'TR.ETPConstituentWeightPercent.Date'
    ],
    parameters = {'SDate': '-2M'}
)
df

Hi, regarding what was written above "I know the RDP Funds API can can provide that." could you please let me know how this could be done? I.e. reproduce the code you provided above with an SDate of -2M but for a non-ETF product, such as the following ID: LP40065886, and using the RDP Funds API? Many thanks in advance
