I noticed that depends on the time of the day I query Refinitiv DataScope Select, data for a particular instrument may or may not be available. I can get a "Not Found" early in the morning but am able to pull the data later in the day. Is there a way to tell when a particular instrument becomes available for data extract?
There is a field "Asset Set Up Date" which seem to serve the purpose but when I tried to retrieve it for follow example using "https://selectapi.datascope.refinitiv.com/RestApi/v1/Extractions/ExtractWithNotes",
{
    "ExtractionRequest": {

            ],

        },
        "Condition": {

        }
    }
}I got a null for this field

}Any one has any advise on this?
