I had created a new order component specification [significant update] in a new cartridge.
The clean, build and deploy are successfully completed.
However, I hit an error when I submit an order to test out.
Invalid Order Specification Fault
Failed to create and start the order due to java.lang.RuntimeException: com.mslv.oms.OMSException: Error amending order  caused by:Cannot find entity in orchestration model: oracle.communications.ordermanagement.orchestration.generation.e@856a44[name=HandOverServicesSignificantUpdates,namespace=COM_SalesOrderFulfillment,type=T=OrderComponentSpec@http://xmlns.oracle.com/communications/ordermanagement/model]
