Future Price Material Master

We have 230 plants where we execute. We created all materials in one dummy plant where we execute costing for all plants and then update the price through MM02 in Accounting View Future Price and enter the valid from date. Then we go to CKMPRP - Maintain Future Prices and maintain the valuation. Then we go to release the future price from CKME - Release Planned Prices . Can any body tell me if there is any problem we can face due to this or its ok.
