Introduction to the Sales Forecast Register

The Sales Forecast register is where you can enter future sales predictions for each Item, as describedin the bullet points below. These sales predictions will provide the basis for all the Production Plan and Purchase Order Plan calculations made in the MRP module.

In this register, you can enterfuture sales predictions for each Item, as follows:

  • Each Sales Forecast should be one week or one month in duration, depending on the Period Type that you have selected in the Forecast Settings setting.

  • For each Item, you should enter one Sales Forecast for each period (i.e. for each week or each month).

  • You can enter more than one Sales Forecast record for each period, but they must contain different Items. You cannot use the same Item in more than one Sales Forecast in the same period (unless you are using Forecast Classes).

  • If you need to enter more than one Sales Forecast for the same period for the same Item, assign different Forecast Classes to the Sales Forecast records. For example, you can use Forecast Classes to represent different branches, allowing you to forecast sales of the same Item in different branches.

  • You must mark a Sales Forecast as OK to make it available to the Production Plan and Purchase Order Plan calculations. After marking a Sales Forecast as OK, no further changes will be possible.

  • It is likely that you will enter Sales Forecasts several weeks or months in advance, and that you will mark them as OK to make them available to the calculations. Entering Sales Forecasts well in advance will ensure there is enough time to produce and purchase the Items in the Forecasts.

    From the point of view of the calculations, future Sales Forecast records will be used in the calculation of the required beginning-of-period stock level figures for each Item. The calculation of these figures depends on the No. of Periods that you have specified in the Forecast Settings setting. If you specify a large No. of Periods figure, you will need to ensure that you have Sales Forecasts for at least that number of periods ahead of your reporting periods, to maintain accuracy
