This feature shows that a user cannot change the Item Type if there is an available stock for that item.
For example, both MAIN and NY warehouses have available In Stock qty for this item (BED-FITTED SHEET).
Notice that BED-FITTED SHEET item type is Inventory Item. Changing the Item Type from “Inventory”, “Production” or “Assembly” to “Kit”, “Service” or “Non-Inventory” is not possible when there are available stocks for that item.
If you try to change Inventory Item to Kit item
Inventory form will prompt you to do an inventory adjustment or zero out the stock first before changing the item type.
