Each control account can have one or more work packages assigned but multiple control accounts cannot be assigned to one Work package.

It is unique identifier, the financial maangement team uses the control account for control and reporting purpose. The scope, cost and schedule information are intergrated & tracked through the control account and EV reproting is done through control account.

WBS component used for project cost accounting

In the cost aggregation the highest level aggretaion is at Control account level, the next is cost baseline creation with contingency reserve adding to the aggregated cost.
