Definition
The Sawtooth chart is a graphical representation of the inventory-over-time data normally shown in the Order Schedule Detail grid.
It can be accessed through the Purchase --> Order Schedule screen, or as a popup when you see the "Sawtooth Chart..." option.
The sawtooth chart can be shown in daily, weekly, or monthly resolution. In the Order Schedule, it uses whatever interval is selected in the Order Schedule display options. In its own popup, you can select your desired interval and use the "Refresh" button to update the display.
- Current Period - A vertical line indicates the current period. You can select if you want to see one year, two years, or all available history on the chart, or none at all.
- Firm Supplies - Yellow bars indicating firm supply (PO, WO, TRX etc)
- Planned Receipts - Maroon bars indicating planned purchases buy StockIQ
- Actuals - AKA independent demand, this is the firm demands (e.g. open sales) still to be serviced. In the historical section, those are historical actual demands
- Operational Forecast(s) - Any of your forecast series showing forecasted demand.
- Expiration Forecast- Purple forecast stacked on any operational forecast, if you are doing expiration forecasting
- Firm Dep Fcst - The firm portion of dependent forecast.
- Dep Fcst - The non-firm portion of dependent forecast
- Projected Available - The black line indicating the projected available quantity of inventory over time
- Cycle Stock Range - This green area represents the area in which you would ideally be planning - your safety stock at the bottom, and your preferred max stock at the top.
- Planned Overstock Range - This light-blue area represents the range between your preferred max stock and your max stock, which helps visualize the effect of supplier mins/maxes. Usually you will observe StockIQ planning you within the cycle stock and planned overstock ranges, so the black line should bounce up and down in a sawtooth fashion in these two areas.
- Overstock Range - This darker blue shaded area is the range between your Max Stock and Excess. Ideally you should not ever be in this range. Above this you are in excess.
If you have Time Phased Statistical Inventory enabled in your Global Replenishment Settings, you will see StockIQ's predictions of these changes over time in the shaded areas moving up and down as demand for the item goes up and down.
