Using Extraction Request template #DataScope.Select.Api.Extractions.ExtractionRequests.PriceHistoryExtractionRequest",
over https://selectapi.datascope.refinitiv.com/RestApi/v1/Extractions/ExtractWithNotes, the value for field "Amount
Outstanding Unscaled" always seems to be None. Is this data (daily time series of amount outstanding for bonds) not available in DataScope ? Or do I need to use some other API or field name ?
