My client is using the free of charge DSWS API ( Datastream Web Service). He is able to retrieve the data he wishes via his normal Eikon Datastream license ( Eikon R&A with DFO) or DWE but he cannot retrieve the data via the Datastream Web Services API. The tickers he is looking for are for example EM00Y00(ZY) EM00Y01(ZY) EM00Y02(ZY) EM00Y03(ZY) EM00Y04(ZY) EM00Y05(ZY) EM00Y06(ZY) EM02Y00(ZY) EM02Y01(ZY). Please get back to me if you need the full excel file of the data examples.
