Meaning of the Fulfillment-inbound-api-v2024-03-20 ListInbounPlans LastUpdateAt

[liuguoxiang9965]

Fulfillment-inbound-api-v2024-03-20 Whether the last updated time field (lastUpdatedAt) returned in each shipment plan in the API listInboundPlans list interface can represent:
After the shipment, boxes, goods and other related information under the shipment plan changes, the last update time field will also change. Please elaborate on the behavior involved in causing the change in the last update time field, such as: change in the status of the shipment;Can anyone help?

If I need to synchronize these data, can I incrementally obtain inboundPlan, shipments, boxes and other information through the last update time?If not, is there any other way to obtain this data incrementally?

Hi,
lastUpdatedAt will update whenever some change occurs to the inbound plan including changing the quantities, once shipment status gets updated, etc. Also we provide couple of FBA Reports where you can shipments data.

@puppsupr Okay, thanks, I probably already know the answer to the first question. Is the second question feasible?

[liuguoxiang9965]

Now there is another problem: I found that the InboundPlan's LastUpdateAt does not effectively represent the most recent update time of the shipment
For example: The last update time of InboundPlan is 2024-09-09, but the most recent update time from the Amazon store is 2024-10-30 (The latest update time of the shipment obtained from the background system)
Corresponding interface to obtain InboundPlan details: FBA Fulfillment-0320 GetInboundPlan interface

@liuguoxiang9965 The update should be due to some related change in the inbound plan. Please open a support case following the guidance here so we can further look into the reason for update.
