Moving items from one fulfillment order to another location

Payments + Shipping & Fulfilment

Hi Shopify support,

I’m working with the fulfillment orders API endpoints and I have the following use case:

  1. FULFILLMENT_ORDER1 on LOCATION1 has the following items:
  • FO1Item1
  • FO1Item2
  • FO1Item3
  1. FULFILLMENT_ORDER2 on LOCATION2 has the following items:
  • FO2Item1

The use case is the following:

  1. I do a first fulfillment fulfilling only FO1Item1 and everything goes ok.
  2. Then I want to do a second fulfillment with the same tracking nb and the following items taken from LOCATION2
    1. FO1Item2
    2. FO1item3
    3. FO2item1

But to do this I will first need to move FO1Item2 and FO1Item3 to LOCATION2 with the move.json endpoint in fulfillment orders. When I do that according to the API this will happen:

Second scenario: Re-assign a subset of the line items belonging to a fulfillment order to a new location. You can specify a subset of line items using the fulfillment_order_line_items field under the FulfillmentOrder parameter (available as of the2023-04 API version), or specify that the original fulfillment order contains line items which have already been fulfilled.> > If the new location is already assigned to another active fulfillment order, on the same order, then the line items are moved to the existing fulfillment order. Otherwise, a new fulfillment order is created

So according to the API doc the expected result should be:

FULFILLMENT_ORDER2:

  1. FO1Item2
  2. FO1item3
  3. FO2item1

But what is happening in fact is that a new Fulfillment order is created containing the items I wanted PLUS the one remaining in FULFILLMENT_ORDER2, and that FULFILLMENT_ORDER2 is closed:

FULFILLMENT_ORDER3:

  1. FO1Item2
  2. FO1item3
  3. FO2item1

That is different from what the API doc is saying. I wanted to confirm what is the expected behavior
