does that mean PHYSICAL_COUNT “resets” the inventory to the number (AKA quantity is an absolute number), whereas adjustments are relative to the current count?
furthermore, whether an adjustment increments or decrements the inventory count would need to be inferred from the TO_STATE and FROM_STATE.
For instance, going from in stock -> sold is decrement, whereas going from none -> in stock is an increment.
Other states include:
RETURNED_BY_CUSTOMER
RESERVED_FOR_SALE
SOLD_ONLINE
