Reserved instance used in another account

Question

When a customer has consolidated billing, if a reserved instance is not used in the account where it was purchased, it will be used in the best suitable linked account that maps with the same characteristics.

Is there a way to trace that account/instance-id where it was used. It is challenging to know who is taking the unused reserved instances for internal budgeting.

Accepted Answer

You can trace it by using [Cost and Usage Report][1]. It shows customers how the RIs are applied. [The Discounted Usage line][2] item describes the instance usage that received a matching RI discount benefit, and is added to customer's bill when they have usage that matches one of their RIs.
