Hi Alexander,
The exact task that you are attempting is not possible.
The only objects that are stored in the repository with IDs are those
that are created explicitly using constructors exported to Excel. So
the QuantLib::Swap object that you are interested in exists in memory
but does not have an ID in the repository.
There is a little technique that can be used to grab such an object,
attach an ID to it, and return it to the spreadsheet. Effectively you
would be implementing a function "qlSwapRateHelperSwap" which would
return the ID of the swap. See
QuantLibAddin::MarketModelMultiProduct::evolution().
Regards,
Eric
