I am trying to understand the debt management module of the TMS, can somebody explain the functionality of this modules?

what a debt management module does in the backend of the TMS. For example when the user enters the details of the debt item e.g. Bond, as well as the the hedge instrusment like Interest rate swap in to the TMS, what will happen, what the system will do after entering all this information by the user. What is the end goal achieved after entering the attributes of the debt item and or instrument in to the system. 

I am a corporate fiance student and working on the solutions thesis on treasury management's debt module.

Thanks
