MRP Forecast Parameters Forecast Models 2008-07-09 22:21:16 When a series of consumption values is analysed, certain patterns can usually be detected. From these patterns it is then possible to differentiate between various forecast models: constant trend seasonal seasonal trend A constant consumption flow applies if consumption values vary very little from a stable mean value.With a trend model, consumption values fall or rise constantly over a lo Read more:Forecast
Model Selection MRP Forecast Parameters 2008-07-09 22:20:13 Before the first forecast can be carried out, you must specify which forecast model the system is to use to calculate the forecast values.There are three basic possibilities:Manual Model Selection Automatic Model Selection Manual Model Selection with Additional System Check Read more:Forecast
Manual Model Selection MRP Forecast Parameters 2008-07-09 22:19:20 If you want to select a model manually, then you must first of all analyse past consumption data to determine whether a distinct pattern or trend exists according to which you can manually select a model for the system.Constant requirements patternIf your past data represents a constant consumption flow, you can then select either the constant model or the constant model with adaption of the smoot Read more:Forecast
Automatic Model Selection MRP Forecast Parameters 2008-07-09 22:18:13 If you do not want to specify a forecast model manually, you must instruct the system to make an automatic selection. The system then analyzes the historical data for different patterns and selects the appropriate model. The following models are possible:Constant model Trend model Seasonal model Seasonal trend model If the system does not detect any regular pattern in the past consumption data Read more:Forecast
Manual Model Selection with Additional System Check MRP Forecast Parameters 2008-07-09 22:17:40 In the third case, you can have a combination of manual and automatic model selection: you specify a model and set the system so that it additionally checks historical values for a seasonal pattern or trend.Possible combinations that you can choose are as follows:You enter a trend model for the forecast model and then let the system check historical data for a seasonal pattern by setting the model Read more:System

Model Initialization MRP Forecast Parameters 2008-07-09 22:17:09 Model initialization is the process of specifying the necessary model parameters, such as the basic value, the trend value and the seasonal indices for the selected forecast model. In each case, initialization occurs during the first forecast for a material. It must also be carried out in cases of structural interruption, that is, if the existing forecast becomes invalid.Which model parameters a Read more:Forecast
Ex-Post Forecast MRP Forecast Parameters 2008-07-09 22:16:20 If more past values are available than the system requires or is to use for model initialization (refer to "Number of historical values" and "Initialization periods" in Forecast
Parameters: Independent of the Forecast Model), then the system will carry out an ex-post forecast. In order to do this, the system divides the time series of past values into two groups. The first group with the older v
Parameter Optimization MRP Forecast Parameters 2008-07-09 22:15:40 For forecast models with exponential smoothing, you can instruct the system to optimize the smoothing factors (see ForecastParameter
s: Dependent on the Forecast Model).If the system is instructed to optimize the smoothing factors, it calculates several parameter combinations and then selects the combination with the lowest mean absolute deviation (MAD). The finer the degree of optimization, the Read more:Optimization
Maintaining MRP Forecast Parameters 2008-07-09 22:15:02 You maintain forecast parameters in the material master record. In order to do this, proceed as is described below:Starting from the menu screen of the material master record, select Material ® Create general. Enter the material type, allocate it to an industry sector and press ENTER. The pop-up window Select View(s) appears on your screen.Select the Forecast

MRP Forecast Parameters: Independent of the Forecast Model 2008-07-09 22:14:23 You can/must maintain the following parameters independent of the method you use for model selection and which model you choose.Period indicatorThe period indicator determines the time interval the system is to use to store consumption or forecast values. You can define the period indicator when maintaining the MRP parameters as well as when maintaining the forecast parameters.Fiscal year variantY Read more:Forecast
MRP Forecast Parameters: Dependent on the Forecast Model 2008-07-09 22:13:30 You can/must maintain the following parameters depending on how you carry out model selection and which model you choose. The relationship between parameters and model selection is shown in the following two tables.Parameters Dependent

Creating Historical Data MRP Forecast Parameters 2008-07-09 08:56:02 Historical data is generally updated in the material master record when stock is withdrawn from the warehouse. However, it is also possible to enter historical data manually, which then forms the basis of the initial forecast.There are two types of historical data (consumption values) in the material master record: total consumption and unplanned consumption values.Total consumption is the total o Read more:Creating

Creating Forecast Values MRP Forecast Parameters 2008-07-09 08:54:03 Forecast values are generally calculated by the system as part of the forecasting process, and then updated in the material master record. However, it is possible to enter forecast values manually, which then form the basis of the planning run.This is how you enter forecast values:1. Once you have specified the required entries on the Forecasting data screen, define whether forecast values are man Read more:Creating

MRP Carrying out the Forecast with Reference to Another Material 2008-07-09 08:53:06 If no historical data exists for materials, which the system can access during the forecast, it is possible to use another material for the forecast. To do this, you must define a so-called reference material for consumption as well as a reference plant, a validity date, and a multiplier.If you have defined a reference material, the system accesses the historical data of the reference material dur Read more:Forecast
Maintaining Parameters Using Profiles Overview 2008-07-09 08:52:13 You can maintain MRP parameters and forecast parameters using profiles. profile is a collection of information used to configure certain objects. It stores standard information that you need repeatedly in almost identical combinations when maintaining different objects.Thus, a profile simplifies data entry and data management.In a profile you specify;• which fields are filled with values when da Read more:Maintaining

MRP Forecast Parameters Changing a Profile 2008-07-09 08:48:23 When you change a profile, the system not only updates the changed values in the profile; it also generates a background job which updates all material master records that have this profile assigned to them. However, this applies only to changes that affect fixed values. A changed document is created automatically for all materials where such changes have occurred.Material master records are updat Read more:Changing

Deleting a Profile MRP Forecast Parameters 2008-07-09 08:46:46 The system also generates the background job PROFILE when you delete a profile. The job is started automatically in the evening. It cancels the profile in every material master record with that profile assigned to it; that is, the profile assignment disappears, but the values themselves remain stored in the material master record.If errors occur while the job is being run, they are recorded in a l Read more:Deleting
