I'm new to Datastream, and I have a limited knowledge of it, but I'm learning so please bear with me! :)
So I know how to find, download, extract, ... sovereign CDS spreads (I'm interested in CDS with 5y and 10y maturity). But I don't how to find their underlying sovereign debt/bond. I don't know how to find, with Datastream, the bond that has been used to calculate a specific CDS spread. For example, I can download the CDS for UK government "GBG5EAC"; but I don't know which 5y sovereign debt/bond in the list I should download when I'm searching for it. The thing is, I need to get the reference code for the bond in order to obtain the corresponding credit rating.
I hope I've been clear enough.
Thanks in advance for your help.
