ISIN returns no best match in GetSymbology or get_data. Records found manually

I am having trouble matching some ISIN codes to their respective company information (attached the list).

I tried the get_symbology() and get_data() methods without luck. However, when I look for each ISIN manually on the RefinitivWorkspace Search Bar, there is information on the company, with a given RIC and all.

I wanted to check if there is another method to match these ISINs with their corresponding identifiers, instead of doing this manually.

Thank you

    Hello @ricardo.henriquez

    The Eikon Data API get_symbology function has the bestMath parameter with the following description:

    When set to True (default), only the primary symbol is requested. When set to False, all symbols are requested.

    I did a quick test with the following code:

    ek.get_symbology(
        list_isin_nas, 
        from_symbol_type='ISIN', 
        to_symbol_type='RIC',
        best_match=False)

    The result is as follows:

    Does this match your requirement?

    Additionally, I highly recommend you contact the Content support team to verify your ISIN names. You can contact the team directly via the https://my.refinitiv.com/content/mytr/en/productsupport.html website.

    Hello @ricardo.henriquez

    Thank you for contacting us. Do your ISIN codes are the valid code list?

    I quickly checked some of the given ISIN codes with the Workspace Search. Workspace suggests a RIC for some of your ISIN codes, but the Workspace Data Item Browser app (DIB) shows that the valid ISIN of that RIC is a different code.

    Example 1:

    AT0000676903 the search bar suggests the RHIM.L RIC

    isin-1.png

    But the Data item browser shows that the RHIM.L's ISIN is NL0012650360

    isin-2.png


    Some ISIN like NO00108611115 or BG1500003188, etc is not available on the Workspace search result at all.

    Example 2:

    BE0003790079 the search bar suggests the BAR.BR RIC.

    isin-3.png

    But the Data item browser shows that the RHIM.L's ISIN is BE0974362940.

    The Eikon Data API query with NL0012650360 and BE0974362940 shows a valid result.

    Hi @ricardo.henriquez

    If you try your list of ISINs on the API Playground with the actual symbology/lookup endpoint, you will note that most that for most of them the response is:

    "Input value does not exist in current time. You can use look-up type endpoint or 'showHistory' parameter to get more information".

    See input and output below.

    @wasin.w @umer.nalla Thank you both for your response.

    I believe some of these ISINs might be delisted/merged companies. Still, I haven't figured out how to programmatically get the suggested/actual ISIN instead, without looking one by one on the DIB or search bar. Thank you again
