I am trying to receive the field IssueISIN from Catalog -> Search -> Derivative Instruments in KNOWLEDGE DIRECT API (http post: http://api.trkd.thomsonreuters.com/api/Search/Search.svc/REST/DerivativeInst_1/GetDerivativeInst_1)
https://www.trkd.thomsonreuters.com/SupportSite/TestApi/Op?svc=Search_1&op=GetDerivativeInst_1#
I am able to receive the field ISIN resp. IssueISIN in the EquitySearch and FundSearch but in DerivativeInstrumentsSearch it seems to be impossible to retrieve the ISIN. Is that so? Also searching for an ISIN is not possible by using "IssuerISIN", but at least works with the field "Code". However, the field "Code" can not be retrieved as well.
Is there any solution for my problem?
