On DSS when I search for RIC for the ISIN US207932AB01 it retunes the two instruments below, both instruments have the same ISIN but different identifiers.
When I try and run a historical request via the DSS REST API using the ISIN 'US207932AB01' it only returns the instrument on the EJV source and not both, which I thought it would have, If I run a similar request for the ISIN 'GB00BH4HKS39'; I get several records returned on various sources.
Without being able to get the RIC from the ISIN we can't get the Time and Sales data.
