Change mode is the way that Order Management handles changes to sales orders during the orchestration process. Change mode determines when Order Management takes a snapshot of the orchestration process and how it applies changes to the fulfillment lines1 Simple change mode takes a snapshot only when the orchestration process starts. It applies changes to all fulfillment lines regardless of their status1 Incremental change mode takes a snapshot only when the orchestration process starts. It applies changes only to the fulfillment lines that are not yet completed1 Advanced change mode takes a snapshot when the orchestration process starts and when a change order is received at an orchestration process step. It applies changes to the fulfillment lines based on the snapshot and the current status of the lines1 None change mode does not take any snapshot and does not apply any changes to the fulfillment lines1 Therefore, the correct answer is C. Advanced, because it is the only change mode that takes a snapshot of the following stages: when the orchestration process starts and when a change order is received at an orchestration process step.
