Use the Gross sales forecast form to record the expected part quantities to be sold, itemized by customer if required. Based on these forecasts, you can start ordering or producing parts, to avoid long lead times.
The Run MRP and Create purchase requirements for stock (time-phased order point method) processes take into account forecast quantities, provided that they fall within the planning horizon on the relevant processing form.
The information registered can also be used to collect data about forecasts and the sales ultimately generated, for example in the form of custom reports.
