Reason and use of these order creation for O2A PIP cartridges when sample order is submitted - Close
1. O2A need to determine if there are any open trouble ticket was created due to all previous order creation failure against the same order number(Revision or multiple revision they all fail), this is due to OSM server currently don't have the information about a just created order is a base or revision order, so O2A order create event handler need to start a work order (CloseCreationFialedTroubleTicketOrder) to run a query and if find any TT then will close it, otherwise the WO will just be completed.
2. O2A also need to determine when order state change to in-progress, if there are any pending response message due to order state early change from in-progress to suspend. If there are pending message, O2A will re-route those message back to its normal response queue. Work order (ResumePendingInBoundMessage) is doing all this.
