I have using Commerce Kickstart and Commerce Marketplace. I have added 2 products into the cart (products from different stores).The problem is when I taken review order page it shows as different order, also different order created. What is wrong with me.I wish to add these two product as the same order.
It sounds like you have something misconfigured. With the Marketplace module, you'll actually have 3 orders created. One is a Marketplace Order and one is a Store Order. It appears that your Store Orders are being displayed instead of the Marketplace Order. Check your pane configuration and ensure that you've enabled the proper marketplace modules and that your Views are showing the Marketplace Order.
