The Days of Stock Remaining calculation forecasts when you're likely to run Out of Stock. By default, we estimate the number of days by dividing the non-hand units by the average number of Units Sold daily during the last 30 Days. Days of Stock Remaining = (Units Inbound + Units Reserved + Units Available) / (Units Sold last 30 Days / 30 ). However, it can be modifed by utilising the controls in the header to calculate the estimate using the Units Sold in the previous 1 Day, 7, 14, 30, 60, 90, 180 or 365 Days. Should be used in conjunction with the Sell-through % calculation.
