Missing attributes in Vendor Purchase Order API response

[ANarayanan-Cervello]

Hi Team,
I am getting the following attributes at an item(ASIN) level from the API response for each purchase order using the endpoint (https://github.com/amzn/selling-partner-api-docs/blob/main/references/vendor-orders-api/vendorOrders.md#get-vendorordersv1purchaseorders) :

'itemSequenceNumber': '1',
'amazonProductIdentifier': 'xxxxxxxxx',
'vendorProductIdentifier': 'xxxxxxxxx',
'orderedQuantity': {'amount': x, 'unitOfMeasure': 'xxx', 'unitSize': x},
'isBackOrderAllowed': False,
'netCost': {'currencyCode': 'USD', 'amount': 'xxx'},
'listPrice': {'currencyCode': 'USD', 'amount': 'xxx'}}]}}

However, when I look for the purchase orders up on the Vendor Central, I can see additional information/attributes
namely-> 'Expected Date', 'Accepted Quantity', 'Quantity received',
'Quantity Outstanding'.

I understand that details like expected date , accepted quantity quantity and quantity received/outstanding are shipment related information. However, why don't we have these added to the existing get-vendorordersv1purchaseorders endpoint, so that the end result mirrors the report that is generated from the portal . Alternatively, we could have a new GET endpoint under Shipments (vendor-shipments-api/vendorShipments.md) , wherein we could retrieve shipment related information by passing in a purchase order number. Thoughts?

@chapmanjw Is there going to be any work for this?

I would also benefit from being able fetch Expected Date, Accepted Qty, and Quantity Received from the API.

I suggest that you take a look at Get purchase order status This one has details on the quantity received (Payload_orderstatus_itemstatus_receivingstatus) and acknowledged (payload_ordersstatus_itemstatus_acknowledgementstatus). Use case guide has a few sample use cases
