## Working with Detail Forecasts

This chapter provides an overview of detail forecasts and discusses how to:

- Create detail forecasts.

- Create forecasts for a single item.

- Review detail forecasts.

- Revise detail forecasts.

- Revise forecast prices.

- Generate a Forecast Price Rollup.

### Understanding Detail Forecasts

Detail forecasts are based on individual items. Use detail forecasts to project demand at the single item level, according to each item's individual history.

Forecasts are based on sales data from the Sales Order History File table (F42119) and the Sales Order Detail File table (F4211). Before you generate forecasts, you use the Refresh Actuals program (R3465) to copy sales order history information from tables F42119 and the F4211 into the Forecast File table (F3460). This table also stores the generated forecasts.

You can generate detail forecasts or summaries of detail forecasts, based on data in table F3460. Data from the forecasts can then be revised.

After you set up the actual sales history on which you plan to base the forecast, you can run the Forecast Generation program (R34650), to generate the detail forecast for one or multiple items. You can then revise the forecast to account for any market trends or strategies that might make future demand deviate significantly from the actual sales history.

The system creates detail forecasts by applying multiple forecasting methods to past sales histories and generating a forecast that is based on the method which provides the most accurate prediction of future demand. The system can also calculate a forecast that is based on a method that you select.

When you generate a forecast for any method, including best fit, the system rounds off the forecast amounts and quantities to the nearest whole number.

When you create detail forecasts, the system:

- Extracts sales order history information from the Forecast File table (F3460).

- Calculates the forecasts by using methods that you select.

- Calculates the percent of accuracy (POA) or the mean absolute deviation (MAD) for each selected forecast method.

- Creates a simulated forecast for the months that you indicate in the processing option.

- Recommends the best fit forecast method.

- Creates the detail forecast in either dollars or units from the best fit forecast.

The system designates the extracted actual records as type AA and the best fit model as BF. These forecast type codes are not hard coded, so you can specify the codes. The system stores both types of records in table F3460.

When creating detail forecasts, the system enables you to:

- Specify the number of months of actual data to use to create the best fit.

- Forecast for individual large customers for all methods.

- Run the forecast in proof or final mode.

- Forecast up to five years into the future.

- Create zero forecasts, negative forecasts, or both.

- Run the forecast simulation interactively.

### Creating Detail Forecasts

This section discusses how to:

- Run the Forecast Generation program.

- Set processing options for Forecast Generation (R34650).

#### Running the Forecast Generation Program

Select Periodic Forecasting Operations (G3421), Create Detail Forecast.

Note. Use the data selection for the Forecast Generation program to create detail forecasts for one or multiple items.

#### Setting Processing Options for Forecast Generation (R34650)

Processing options enable you to specify the default processing for programs and reports.

Method 1-3

These processing options specify which forecast types that the system uses when calculating the best fit forecast. You can also specify whether the system creates detail forecasts for the selected forecast method.

Enter 1 to use the forecast method when calculating the best fit. The system does not create detail forecasts for the method. If you enter zero before the forecast, for example, 01 for Method 1: Percent Over Last Year, the system uses the forecast method when calculating the best fit and creates the forecast method in the Forecast File table (F3460). If you leave the field blank, the system does not use the forecast method when calculating the best fit and does not create detail forecasts for the method.

A period is defined as a week or month, depending on the pattern that is selected from the Date Fiscal Patterns table (F0008). For weekly forecasts, verify that you have established 52 period dates.

1. Percent Over Last Year | Specify which type of forecast to run. This forecast method uses the Percent Over Last Year formula to multiply each forecast period by a percentage increase or decrease that you specify in a processing option. This method requires the periods for the best fit plus one year of sales history. This method is useful for seasonal items with growth or decline. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 01: Uses the Percent Over Last Year formula to create detail forecasts.
2. Percent | Specify the percent of increase or decrease used to multiply by the sales history from last year. For example, type 110 for a 10 percent increase or type 97 for a 3 percent decrease. Values are any percent amount, however, the amount cannot be a negative amount. Enter an amount to use or select it from the Calculator.
3. Calculated Percent Over Last Year | Specify which type to run. This forecast method uses the Calculated Percent Over Last Year formula to compare the periods specified of past sales to the same periods of past sales of the previous year. The system determines a percentage increase or decrease, then multiplies each period by the percentage to determine the forecast. This method requires the periods of sales order history indicated in the processing option plus one year of sales history. This method is useful for short term demand forecasts of seasonal items with growth or decline. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 02: Uses the Calculated Percent Over Last Year formula to create detail forecasts.
4. Number of Periods | Specify the number of periods to include when calculating the percentage increase or decrease. Enter a number to use or select a number from the Calculator.
5. Last Year to This Year | Specify which type of forecast to run. This forecast method uses Last Year to This Year formula which uses last year's sales for the year's forecast. This method uses the periods best fit plus one year of sales order history. This method is useful for mature products with level demand or seasonal demand without a trend. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 03: Uses the Last Year to This Year formula to create detail forecasts.

Methods 4-6

These processing options specify which forecast types that the system uses when calculating the best fit. You can also specify whether the system creates detail forecasts for the selected forecast method.

1. Moving Average | Specify which type of forecast to run. This forecast method uses the Moving Average formula to average the months that you indicate in the processing option to project the next period. This method uses the periods best fit from the processing option plus the number of periods of sales order history from the processing option. You should have the system recalculate this forecast monthly or at least quarterly to reflect changing demand level. This method is useful for mature products without a trend. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 04: Uses the Moving Average formula to create detail forecasts.
2. Number of Periods | Specify the number of periods to include in the average. Enter a number to use or select a number from the Calculator.
3. Linear Approximation | Specify which type of forecast to run. This forecast method uses the Linear Approximation formula to compute a trend from the periods of sales order history indicated in the processing options and projects this trend to the forecast. You should have the system recalculate the trend monthly to detect changes in trends. This method requires periods best fit plus the number of periods that you indicate in the processing option of sales order history. This method is useful for new products or products with consistent positive or negative trends that are not due to seasonal fluctuations. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 05: Uses the Linear Approximation formula to create detail forecasts.
4. Number of Periods | Specify the number of periods to include in the linear approximation ratio. Enter the number to use or select a number from the Calculator.
5. Least Squares Regression | Specify which type of forecast to run. This forecast method derives an equation describing a straight line relationship between the historical sales data and the passage of time. Least Squares Regression (LSR) fits a line to the selected range of data such that the sum of the squares of the differences between the actual sales data points and the regression line are minimized. The forecast is a projection of this straight line into the future. This method is useful when there is a linear trend in the data. This method requires sales data history for the period represented by the number of periods best fit plus the number of historical data periods specified in the processing options. The minimum requirement is two historical data points. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 06: Uses the Least Squares Regression formula to create detail forecasts.
6. Number of Periods | Specify the number of periods to include in the regression. Enter the number to use or select a number from the Calculator.

Methods 7-8

These processing options let you specify which forecast types that the system uses when calculating the best fit. You can also specify whether the system creates detail forecasts for the selected forecast method.

1. Second Degree Approximation | Specify which type of forecast to run. This method uses the Second Degree Approximation formula to plot a curve based on the number of periods of sales history indicated in the processing options to project the forecast. This method adds the periods best fit and the number of periods, and then multiplies by three. You indicate the number of periods in the processing option of sales order history. This method is not useful for long term forecasts. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 07: Uses the Second Degree Approximation formula to create detail forecasts.
2. Number of Periods | Specify the number of periods to include in the approximation. Enter the number to use or select a number from the Calculator.
3. Flexible Method | Specify which type of forecast to run. This forecast method specifies the periods best fit block of sales order history starting n months prior and a percentage increase or decrease with which to modify it. This method is similar to Method 1. Percent Over Last Year, except that you can specify the number of periods that you use as the base. Depending on what you select as n, this method requires periods best fit plus the number of periods indicated in the processing options of sales data. This method is useful for a planned trend. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 08: Uses the Flexible method to create detail forecasts.
4. Number of Periods | Specify the number of periods before the best fit that you want to include in the calculation. Enter the number to use or select a number from the Calculator.
5. Percent Over Prior Period | Specify the percent of increase or decrease for the system to use. For example, type 110 for a 10 percent increase or type 97 for a 3 percent decrease. You can enter any percent amount, however, the amount cannot be a negative amount.

Methods 9

These processing options let you specify which forecast types that the system uses when calculating the best fit. You can also specify whether the system creates detail forecasts for the selected forecast method.

1. Weighted Moving Average | Specify which type of forecast to use. The Weighted Moving Average forecast formula is similar to Method 4: Moving Average formula, because it averages the previous number of months of sales history indicated in the processing options to project the next month's sales history. However, with this formula you can assign weights for each of the prior periods in a processing option. This method requires the number of weighted periods selected plus periods best fit data. Similar to Moving Average, this method lags demand trends, so this method is not recommended for products with strong trends or seasonality. This method is useful for mature products with demand that is relatively level. Values are: Blank: Does not use this forecast. 1: Calculates the best fit forecast. 09: Uses the Weighted Moving Average formula to create detail forecasts.
2. One Period Prior through 13. Twelve Periods Prior | Specify the weight to assign to one period through 12 periods prior for calculating a moving average. Enter the number to use or select it from the Calculator.
14. Periods to Include | Specify the number of periods to include. Enter the number to use or select a number from the Calculator.

Method 10-11

These processing options let you specify which forecast types that the system uses when calculating the best fit. You can also specify whether the system creates detail forecasts for the selected forecast method.

1. Linear Smoothing | Specify which type of forecast to run. This forecast method calculates a weighted average of past sales data. You can specify the number of periods of sales order history to use in the calculation (from 1 to 12) in a processing option. The system uses a mathematical progression to weigh data in the range from the first (least weight) to the final (most weight). Then, the system projects this information for each period in the forecast. This method requires the periods best fit plus the number of periods of sales order history from the processing option. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 10: Uses the Linear Smoothing method to create detail forecasts.
2. Number of Periods | Specify the number of periods to include in the smoothing average. Enter the number to use or select a number from the Calculator.
3. Exponential Smoothing | Specify which type of forecast to run. This forecast method uses one equation to calculate a smoothed average. This becomes an estimate representing the general level of sales over the selected historical range. This method is useful when there is no linear trend in the data. This method requires sales data history for the time period represented by the number of periods best fit plus the number of historical data periods specified in the processing options. The minimum requirement is two historical data periods. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 11: Uses the Exponential Smoothing method to create detail forecasts.
4. Number of Periods | Specify the number of periods to include in the smoothing average. Enter the number to use or select a number from the Calculator.
5. Alpha Factor | Specify the alpha factor, a smoothing constant, the system uses to calculate the smoothed average for the general level or magnitude of sales. You can enter any amount, including decimals, from zero to one.

Method 12

These processing options let you specify which forecast types that the system uses when calculating the best fit. You can also specify whether the system creates detail forecasts for the selected forecast method.

1. Exponential Smoothing with Trend and Seasonality | Specify which type of forecast to run. This forecast method calculates a trend, a seasonal index, and an exponentially smoothed average from the sales order history. The system then applies a projection of the trend to the forecast and adjusts for the seasonal index. This method requires months best fit plus two years of sales data and is useful for items that have both trend and seasonality in the forecast. Use the processing options to enter the alpha and beta factor rather than have the system calculate them. Values are: Blank: Does not use this method. 1: Calculates the best fit forecast. 12: Uses the Exponential Smoothing with Trend & Seasonality method to create detail forecasts.
2. Alpha Factor and 3. Beta Factor | Specify the alpha factor or beta factor, smoothing constants that the system uses to calculate the smoothed average for the general level or magnitude of sales. You can enter any amount, including decimals, from zero to one.
4. Seasonality | Specify whether the system includes seasonality in the calculation. Values are: 0: Does not include seasonality. 1: Includes seasonality. Blank: Does not include seasonality.

Defaults

These processing options let you specify the defaults that the system uses to calculate forecasts. The system extracts actual values from Sales History and stores the forecasts that are generated in the Forecast File table (F3460). You can define forecast types for Actuals (AA) and best fit (BF).

1. Actuals Forecast Type | Specify the forecast type that identifies the sales order history used as the basis for the forecast calculations, or Actuals. Forecast type is a user-defined code (34/DF) that identifies the type of forecast to run. Enter the forecast type to use as the default value or select it from the Select User Define Code form.
2. Best Fit Forecast Type | Specify the forecast type that is generated as a result of the best fit calculation. Forecast type is a user-defined code (34/DF) that identifies the type of forecast to run. Enter the forecast type to use as the default value or select it from the Select User Define Code form.

Process

The system applies the selected forecasting methods to past sales order history and compares the forecast simulation to the actual history. When you generate a forecast, the system compares actual sales order histories to forecasts for the months or weeks that you indicate in the processing option, and computes how accurately each of the selected forecasting methods would have predicted sales. Then the system recommends the most accurate forecast as the best fit.

Mean Absolute Deviation (MAD) is the mean of the absolute values of the deviations between actual and forecast data. MAD is a measure of the average magnitude of errors to expect, given a forecasting method and data history. Because absolute values are used in the calculation, positive errors do not cancel out negative errors. When comparing several forecasting methods, the one with the smallest MAD has is the most reliable for that product for that holdout period.

Percent of Accuracy (POA) is a measure of forecast bias. When forecasts are consistently too high, inventories accumulate and inventory costs rise. When forecasts are consistently too low, inventories are consumed and customer service declines. A forecast that is ten units too low, then eight units too high, then two units too high is an unbiased forecast. The positive error of ten is canceled by negative errors of eight and two.

1. Mode | Specify whether the system runs in proof or final mode. Values are: Blank: Proof mode, creating a simulation report. 1: Final mode, creating forecast records.
2. Large Customers | Specify whether to create forecasts for large customers. Based on the Customer Master table (F0301), if the ABC code is set to A and this option is set to 1 the system creates separate forecasts for large customers. Values are: Blank: Does not create large customer forecasts. 1: Creates large customer forecasts.
3. Weekly Forecasts | Specify weekly or monthly forecasts. For weekly forecasts, use fiscal date patterns with 54 periods. For monthly forecasts, use fiscal date patterns with 14 periods. Values are: Blank: Monthly forecasts. 1: Weekly forecasts.
4. Start Date | Specify the date on which the system starts the forecasts. Enter a date to use or select a date from the Calendar. If you leave this field blank, the system uses the system date.
5. Forecast Length | Specify the number of periods to forecast. You must have previously established fiscal date patterns for the forecasted periods. If you leave this field blank, the system uses 3.
6. Actual Data | Specify the number of periods of actual data that the system uses to calculate the best fit forecast. If you leave this field blank, the system uses 3. The system applies the selected forecasting methods to past sales order history and compares the forecast simulation to the actual history. When you generate a forecast, the system compares actual sales order histories to forecasts for the months or weeks you indicate in the processing option and computes how accurately each of the selected forecasting methods would have predicted sales. Then, the system recommends the most accurate forecast as the best fit.
7. Mean Absolute Deviation | Specify whether the system uses the Mean Absolute Deviation formula or the Percent of Accuracy formula to calculate the best fit forecast. Values are: Blank: Percent of Accuracy formula. 1: Mean Absolute Deviation formula.
8. Amounts or Quantity | Specify whether the system calculates the best fit forecast using amounts or quantities. If you specify to use amounts, you must also extract sales history using amounts. This also affects forecast pricing. Values are: Blank: Quantities. 1: Amounts.
9. Fiscal Date Pattern | Specify the fiscal date pattern type to use for the forecast calculations. When generating weekly forecasts, the fiscal date pattern defined here must be set up for 52 periods.
10. Negative Values | Specify whether the system displays negative values. Values are: Blank: Substitutes a zero value for all negative values. 1: Displays negative values.

Interop

This processing option lets you specify the transaction type that the system uses for interoperability.

1. Transaction Type | Specify the transaction type used for interoperability. Values are: Blank: Does not create outbound forecasts. JDEFC: Creates outbound forecasts.

### Revising Detail Forecasts

This section provides an overview of detail forecast revisions and discusses how to revise detail forecasts.

#### Understanding Detail Forecast Revisions

After you generate and review a forecast, you can revise the forecast to account for changes in consumer trends, market conditions, competitor activities, marketing strategies, and so on. When you revise a forecast, you can change information in an existing forecast manually, add or delete a forecast, and enter descriptive text for the forecast.

You can access the forecasts that you want to revise by item number, branch/plant, forecast type, or any combination of these elements. You can specify a beginning request date to limit the number of periods.

As you revise the forecast, be aware that these combinations must be unique for each item number and branch record:

- Forecast type

- Request date

- Customer number

For example, if two records have the same request date and customer number, they must have different forecast types.

#### Form Used to Revise Detail Forecasts

Form Name | FormID | Navigation | Usage
Detail Forecast Revisions | W3460A | Periodic Forecasting Operations (G3421), Enter/Change Forecast On Work With Forecasts, locate a forecast to revise. | Revise detail forecasts. To associate text or drawings with a forecast type, select the row and then select Attachments from the Form menu.

#### Revising Detail Forecasts

Access the Detail Forecast Revisions form.

U/M (unit of measure) | Enter a user-defined code (00/UM) that indicates the quantity in which to express an inventory item, for example, CS (case) or BX (box).

### Revising Forecast Prices

This section provides an overview of forecast price revisions and discusses how to revise forecast prices.

#### Understanding Forecast Price Revisions

You can enter prices for unique combinations of item number, branch/plant, forecast type, and customer number. All these values are stored in the Forecast Prices table (F34007), and are used to extend the amount or quantity on a detail forecast record in the Forecast File table (F3460) and the Forecast Summary File table (F3400). You can roll up these prices to the higher level items in the forecast hierarchy by using the Forecast Price Rollup program (R34620).

If the forecast is stated in terms of quantity, you can use table F34007 to extend the forecast in amounts, for example, as a projection of revenue. In the case of a sales forecast, the forecast might already be stated in terms of revenue. In this case, you might want to convert the forecast into quantities to support production planning.

Effective Date | Enter a date that indicates when a component part goes into effect on a bill of material or when a rate schedule is in effect. The default is the current system date. You can enter future effective dates so that the system plans for upcoming changes. Items that are no longer effective in the future can still be recorded and recognized in Oracle's JD Edwards EnterpriseOne Product Costing system, JD Edwards EnterpriseOne Shop Floor Management system, and Oracle's JD Edwards EnterpriseOne Capacity Planning system. The JD Edwards EnterpriseOne Requirements Planning system uses Material Requirements Planning (MRP) to determine valid components by effectivity dates, not by the bill of material revision level. Some forms display data based on the effectivity dates you enter.
