Hello. When using EIKON DATA API get_data() to retrieve a field such as TR.DividendYield for a specific date say 2019-08-31, the data is not available for some stocks on that specific date but is available for an earlier date say 2019-08-30. Is there any query parameter I can add to make get_data() return any most recent data without me issue another query for that earlier date? Thank you.
