When you enter a sales order for a configurable product/material in R/3, you enter the configuration. The configured sales orders can then consume the forecast for the configuration. This is available for both CDP and CBF characteristics.
This function is closely integrated with SAP R/3 where you create sales orders thus configuring the product.
When setting up the system, you have to decide whether you want to work with characteristics-based forecasting (CBF) or characteristics-dependent planning (CDP). These two methods use characteristics that are technically different (see Planning with Characteristics).
Certain settings have to be made for the material in SAP R/3 and product in SAP APO in order for consumption to take place. For more details see Prerequisites in R/3 for Consumption of Configured Products. If you are working with CDP, you must assign the class to the product in the product master.
This optional feature uses descriptive characteristics to integrate the sales order that is created in R/3 with characteristics-based forecasting and characteristics-dependent planning in SAP APO. This restricts the characteristics that you use to those with pre-defined values. There is also a BAdI (/SAPAPO/DM_SEL_MOD) that you can use to add your own logic and for instance assign ranges in a sales order to a particular value.
1. In the integration model (see Transfer of Data for CBF from SAP R/3 to SAP APO) you must also include an ATP check and sales orders for the products.
2. You proceed as in the normal CBF process (even if you are using CDP characteristics). However, after you have created the CBF tables and profiles, you create a consumption group. As well as the characteristics for product and location, you should also include the characteristics that the system generates for the configuration characteristics. You assign this consumption group to the products to be planned. Note that you can only do this in SAP APO, not in R/3.
3. You create a forecast in Demand Planning using the usual functions. When you release the demand plan to SNP PP/DS, enter the consumption group (if you are releasing directly, you can find this field by choosing the Extended button in the middle of the screen).
4. You create sales orders in SAP R/3 during which you configure the material. The sales order may contain more characteristics than in the consumption group. However, all characteristics in the consumption group must be in the sales order.
5. The forecast is consumed if the characteristic values in the sales order are the same as those in the forecast.
In the standard case CBF/CDP uses requirements strategy 30 that uses the individual planning segment. This segment is not visible in SNP. SNP only uses the net segment. As a result neither the forecast demand or the demand from sales orders can be seen or planned in SNP.
SNP cannot plan with characteristics. However, the characteristic assignments remain and can be evaluated in PP/DS. If you want to plan products in SNP without reference to a characteristic, you can create your own requirements strategy.
