Create a Order XML in Websphere Commerce

If we hhe inventory system as DOM then the order will goes to external system  and  inventory also process from external system only.

But We have a store in ATP and NON ATP then still if the order goes to external system or generate as a xml file then we have to extend the command
com.ibm.commerce.order.event.ProcessOrderSubmitEventCmdImpl and skip the inventory system check. then automatically the orders goes to external system.
