Design a BPMN modeling diagram for the invoice checking scenario given below. (Marking Scheme: 10 marks =4 marks for process + 2 for process + 2 mark for relationship + 2 mark for cardinality) The approval workflow is a typical sales quote with discount approval, it is starting from employee submitting a sales quote with a discount for manager approval. 1. Staff or the Employee raises and submits a sales quote to the line manager. 2. The line manager reviews the sales quote and discount level to either approve or reject. 3. If all information is correct, and the discount meets agreed levels, the sales quote is sent for approval and an approved notification is sent and handle and process end. 4. If the sales quote contains a discount above agreed levels, it is processed as rejected, with either a rejected notification being sent or to be resubmitted with a revised discount level. 5. If an error occurs during the execution of the "Handle notification" activity, this error is caught by the attached Error Event, the activity is interrupted and the flow moves down the alternative path towards the "Handle notification Failure" activity back to employee
