Configured inventory revaluation options

Hi

We are working in E9.2 and configured items /its components are setup with 07 cost method. The question is how do we revalue the already existing configured items inventory whenever we update 07 cost of the components used in the configured items.  Understand that configured items does gets cost at the time of SO entry based on P/Q/R rules and configured item/per sales order has unique cost populated. Not sure how do we handle the inventory revaluation of already existing configured products. Appreciate your inputs.

Thanks

Thiru
