Hello!

We very much need inventory item Replenishment information to for our WMS system. Hope you could expose this information to API.

Replenishment class -information is most needed if others are more difficult to expose.

Hello Teemu, 

could you please also specify the operation (GET-PUT-POST) that you'd like to get "Replenishment class" field exposed via the Inventory Endpoint ?

Replenishment information to GET InventoryItem endpoint is most needed.
