Wrong quantity in Product Quantities By Warehouse
The quantity computed by "Product Quantities By Warehouse" can be wrong if the first move of the product is today. This is because we always add a fake record on today and the quantity computation based on delta requires that dates are ordered by also unique. In our case there will be two computation for today, the first one is right bu the second will be with start=today and end=today so it overrides the computation with zero.
