A forecast of future requirements, based on past consumption figures, is needed to support some requirements planning methods. In some cases, the forecast is compulsory, in others, it is used to provide additional, optional information. The forecast is carried out before requirements are planned.

!) Define MRP type relevent fro forcasting like VV.

2) Maintain firecasting view in material master with suitable forecast profile.

2) enter the past consumption data in the additional data tab "consumption"

4) now execute the forecast from MP30 or from MM02 forecasting view.

Forecast reqs will be copied in MD04 once you save the material master.

If any question then let me know.

The Forecast in SOP

With the forecast, you can estimate the future progression of values in a time series on the basis of past history. You do this either online or in the background.

In standard SOP, you can forecast the sales quantities of a product group or material. The system bases the forecast on the historical consumption of materials. It then aggregates these results to the product group level. Consumption data includes every kind of goods issue, even goods that have been written off as scrap.

In flexible planning, you can forecast any key figure that you want, provided that it has been defined for forecasting in Customizing (in Set parameters for info structures and key figures). The system bases the forecast on the actual values of this key figure. In level-by-level planning, you can also base the forecast on historical consumption data. In this case, the information structure must contain the characteristics "material" and "plant," and you must set the Consumpn. indicator in the forecast profile.

In level-by-level planning, you can base the forecast on the consumption quantities of a "reference material." This is useful if you do not have any historical values for a material; for example, because it is new. You define the reference material in the material master record.

The historical data is automatically aggregated to the current planning level before the forecast is carried out. If you run the forecast online, this is the planning level on which you are working in the planning table. If you run the forecast in the background, this is the planning level you define in the job variant.

Forecast Models

When a series of consumption values is analyzed, it normally reveals a pattern or patterns. These patterns can then be matched up with one of the forecast models listed below:

Constant¾consumption values vary very little from a stable mean value

Trend¾consumption values fall or rise constantly over a long period of time with only occasional deviations

Seasonal¾periodically recurring peak or low values differ significantly from a stable mean value

Seasonal trend¾continual increase or decrease in the mean value

Copy of actual data (no forecast is executed)¾copies the historical data updated from the operative application, which you can then edit

Irregular¾no pattern can be detected in a series of historical consumption values
