Purpose

To be able to carry out Characteristics-Based Forecasting, you must configure the system. You define a CBF table and assign it to the product. The CBF table contains details about the CBF-characteristics to use. You can do this either directly or automatically.

If you want to plan products taking dependencies between characteristics into account, you have to use the first method.

Example

You have noticed that people who order the most powerful engine for a car, tend to prefer the color black. You wish to plan this combination separately. Another example is that some combinations are to be excluded for technical or marketing reasons. The most powerful engine is not offered with a manual 4-gear transmission.

If you assume the characteristics are mutually independent, you can use the second method, which requires less effort. 

Prerequisites

You have created a planning area for use with CBF as described in Creation of Planning Areas and Planning Books for Use in CBF.

Process

Direct

...

       1.      Create at least one CBF table. CBF tables contain details of the characteristics to be used and the permissible values and combinations. The tables are not related to individual products. From the SAP Easy Access screen, choose Master Data ® Application-Specific Master Data ® Demand Planning ® Configured Products ® Maintain Master Data for CBF.

As the initial object on the next screen, choose CBF table. Do not enter a name for the table at this stage. Choose Create.

In the top left-hand screen area choose the Create a New Table icon (This graphic is explained in the accompanying text). In the fields that appear enter a name and a description for the table. Choose Enter.

       2.      You now assign characteristics to the table. In the lower left-hand screen area, you can see characteristics that have already been assigned to CBF tables. You can assign one or more of these characteristics to the current table by selecting them and either using drag and drop or choosing This graphic is explained in the accompanying text with the quick info text Assign Characteristics to Table. Alternatively, if the characteristic you want to use has not yet been assigned to a CBF table, go to the Structure tab page in the lower right-hand screen area. If necessary, choose This graphic is explained in the accompanying text with the quick info text Add Characteristics to create a new row. In the Char. Name column, enter a characteristic by using the F4 help. Here you can choose from  all characteristics in the system.

You can also create new characteristics by double-clicking on an empty characteristic field on the Structure tab page. Similarly by double-clicking on an existing entry you can edit a characteristic that has already been created.

Choose Save.

       3.      The next step is to decide which characteristic value you want to use for planning purposes. In the case of tables with more than one characteristic, you specify the combinations that are relevant for planning. 

In the lower left-hand screen area go to the Contents tab page. You can enter single combinations by choosing This graphic is explained in the accompanying text with the quick info text Add New Entries, double-clicking on individual fields, and then choosing one of the characteristic values. Alternatively, you can choose This graphic is explained in the accompanying text with the quick info text Assign New Combinations. A dialog box appears. On the left-hand side, you can see all possible characteristic values. Select the values with which you want to work and choose This graphic is explained in the accompanying text with the quick info text Suggest New CBF Combination. The system generates all the possible combinations. You can then delete combinations that you do not require. Choose Enter. The combinations appear on the previous tab page.

Save the assignments.

       4.      Maintain the CBF profile.

For more details on this step, see Maintaining CBF Profiles.

...

       1.      Create the necessary classes to contain the CBF-characteristics. Choose Master Data  ® Classification System ® Classes. See Creating Characteristics and Classes for Use in CBF in SAP APO.

       2.      Enter integrated profile maintenance in the product view. Proceed as  described in Maintaining CBF Profiles, steps 1-5.

       3.      Instead of manually assigning tables, choose This graphic is explained in the accompanying text with the quick info text Create Profile with Class in the top left-hand screen area. The system automatically copies all the characteristics with all their values into the profile. You can subsequently delete characteristics or characteristic values.

       4.      Save the profile.
