for example, cross subsidiary fulfillments requires an inventorylocation default value that may not be exposed in rest

if you have favorable account configuration, then you want to specify which lines you wish to fulfill using the itemReceive checkbox, which will require you to understand how keys work while Working with Sublists

I’m looking into this now.

Having trouble creating a sales order with the following flag ticked as i cannot find the relevant field in the WSDL

for anyone wondering, it's not possible at all via webserivce to create cross sub fulfilment order

might be available via Rest API

and with cross sub fuliflment turned on, SOAP webservice initialize requests for Item Fulfilment will all error out with 'VALID_LINE_ITEM_REQD'

great feature 🙂
