Hi,

I want to disable the inventory, because we don't need it. So in the commerce manager I've set the inventory tracking and inventory status to disable on a variation.

Whenever I try to order a project (reproduced this on the QuickSilver demo site (https://github.com/episerver/Quicksilver)) the Workflow engine returns me the warning: 

Item "" has been removed from the cart because it is no longer available or there is not enough available quantity.

Whenever I set the Max Quantity setting on the variable to something higher then 0, it starts working. This was also confirmed when I debug activity: CheckInventoryActivity

The below method is called and eventually it will set the lineItemQty to 0 and the changeQtyReason.Add("by Max Quantity setting"). 

protected Decimal GetNewLineItemQty(LineItem lineItem, List changeQtyReason, Shipment shipment)
    {
      Decimal lineItemQty = shipment != null ? Shipment.GetLineItemQuantity(shipment, lineItem.LineItemId) : lineItem.Quantity;
      if (lineItemQty < lineItem.MinQuantity)
      {
        lineItemQty = lineItem.MinQuantity;
        changeQtyReason.Add("by Min Quantity setting");
      }
      else if (lineItemQty > lineItem.MaxQuantity)
      {
        lineItemQty = lineItem.MaxQuantity;
        changeQtyReason.Add("by Max Quantity setting");
      }
      if (!this.InventoryTrackingEnabled(OrderGroupActivityBase.GetEntryRowForLineItem(lineItem)))
        return lineItemQty;

I would expect whenever I disable the inventory I would not set the Max Quantity on the variation?
