I am working on a C# app with a service reference to the datastream service. Is there a way to request the available requestable static and timeseries datatypes for a given symbol name (e.g. "<VOD.L>")? Similar to what product.datastream.com offers via the datatype search functionality? If there is no such way based on a specific symbol, a request via its security type (Equities, Commodities, Futures etc.) would be fine as well. We need this to offer a dynamic GUI for the user based on a selected symbol.
