Order Management Sub System - Order Processing - Part 1

When ever we submit order, There are several action WC considers to complete the submission.

1.  Order Process command is triggered.
2. If BusinessFlowEventListener component is enabled in ws-server-*.xml, unified business function will be called.
3. Flow type is OrderProcess . ProcessOrderCmdImpl task command is called.

In BusinessFlowEventListener

• Execute OrderProcessPreApprovalCmd, which invokes PreProcessOrderCmd
• Execute OrderProcessCheckApprovalCmd to check whether approval is required
• Execute OrderProcessPostApprovalCmd, which invokes ProcessOrderCmd

     4.  ProcessOrder command will do inventory check , payment finalization, tax calculation to complete the order.

Note:

If your store does not require approval of the order, You do not require Business Flow. Set BusinessFlowEventListener to false in ws-server.xml. This will call processOrderCmd Directly.
