The Usage view displays usage information including qualified and actual usage, stocking unit of measure, number of stockout days, the percentage dip below the safety stock for the current period and the last 12 periods and the stockout date..
The Usage view only displays Qualified usage when it differs from Actual usage or when a flag exists. This allows for better readability so it is easy to pick out the anomalies. If a an inquiry line doesn't show the qualified usage, that means it is the same as the actual usage.
