The Innovation Central Warehouse module is where you may choose to move challenges and Ideas after an event has ended. This is one of two archiving options available in Innovation Central; the other is to use the local Archive Space in the IdC module.
Ideas moved to the Warehouse are not included in any reporting. You can move Ideas from the Warehouse back to the originating IdC module, or another IdC module, at any time.
The only users allowed to use the Warehouse module are those specifically provided with Warehouse Admin access.
