Negotiation Requirements Setup Best Practice

Hi Team, I’m a newbie and after some input into structure of requirements and reusable requirements lists to meet needs of large negotiations.  We are on 12.1.3 and starting to implement Sourcing module, which we have had for a long time.

We have a large number of different Sourcing needs with a lot of similar requirements, keeping requirements lists grouped by Business Unit is good for Buyers, but I’m struggling with potential duplicates.  I am keen to know how implementations have structured their requirements knowing that requirement name needs to be unique.

An example being an IT Solution with hundreds of functional and non-functional requirements that need answering.
