Hi Louise, thanks for raising this in the community. You are right; for any products that have gaps in stock, whether that be due to seasonality or another break in production where you are likely to be out of stock for a number of months, this report will continue going into negative figures. If you were to then add stock, then this would reduce the negative forecasted figure by the amount of stock that has been added. This feature does, however, work very well for products in regular production and will help you accurately forecast the product stock availability. I appreciate what you are saying here and how this could be improved; if you could raise this as a feature request, that would be great! Let me know if you need anything else. Cheers!
