This routine allows you to simulate the retrieval of forecasted demand for an item/warehouse combination. This function is used in many other places in the system to estimate a forecasted demand during a specified time span, for one item/warehouse record. The function requires a start time and a time span length and accumulates from the period forecasts in the Forecast file to get a total forecasted demand for the requested time span. Note that the time span does not need to be fixed forecast periods.
Note: The calculation you make here does not result in an update of the Inventory Control system. These calculations are simulated.
- Item
- Enter the item code of the item/warehouse combination for which you want to calculate a simulated forecast demand.
- Warehouse
- Enter the warehouse code of the item/warehouse combination for which you want to calculate a simulated forecast demand.
- Start date
- Enter the start date for when you want this calculation to begin. The start date must be within the range of active forecast periods. If you do not enter a start date, the Start period field must be completed.
- Start period
- Enter the start period for when you want this calculation to begin. The start period must be within the range of active forecast periods. If you do not enter a start period, the Start date field must be completed.
- Number of days
- Enter the number of days from the start date or start period that you want this calculation to include. If you enter a value here, then do not complete the Number of weeks, Number of months, or Number of periods fields.
- Number of weeks
- Enter the number of weeks from the start date or start period that you want this calculation to include. If you enter a value here, then do not complete the Number of days, Number of months, or Number of periods fields.
- Number of months
- Enter the number of months from the start date or start period that you want this calculation to include. If you enter a value here, then do not complete the Number of days, Number of weeks, or Number of periods fields.
- Number of periods
- Enter the number of periods from the start date or start period that you want this calculation to include. If you enter a value here, then do not complete the Number of days, Number of weeks, or Number of months fields.
- Forecast demand
- After you have the data for this simulation, click OK. This field then displays the simulated forecast demand value calculated according to the parameters that you established in the above fields.
- Unit
- Displays the item unit, but can be changed.
