Disaggregating Demand Data in Collaborative Sales Forecasting
In the collaborative sales forecasting (CSF) process, you release demand data from CSF to short-term forecasting after you have run a consensus finding in CSF. When you release demand data from CSF to short-term forecasting, SAP Supply Network Collaboration (SAP SNC) must disaggregate the demand
data it has received from statistical forecasting from weekly to daily time buckets. It disaggregates the data because short-term forecasting displays data in daily time buckets. In the supplier-lead process variant, the forecast data received from CSF is in weekly time buckets. The system disaggregates
the data during release using the demand weighting factor of the forecasting process (time series type VMIP1
and key figure DWFACTOR
). The distribution pattern for disaggregation is based on the key figure DWFACTOR
.
In the customer-lead process variant, forecast and planning is done on a daily time bucket level. Therefore no additional disaggregation takes place when the final consensus forecast is sent to short-term forecasting.
If you are using the factory calendar for the CSF process, you have a forecast profile in which you have defined the factory calendar you are using. To enable the factory calendar, you have selected the Factory Calendar enabled
checkbox on the SAP
Easy Access
screen under .
If you are using a factory calendar, SAP SNC disaggregates the total quantity from the weekly buckets in CSF and distributes the quantity among the daily buckets in short-term forecasting. SAP SNC distributes the quantities based on the working days you have defined in your factory calendar.
To determine how SAP SNC disaggregates quantities and distributes them among the daily buckets in cases of holidays and other events, you can make calendar adjustments in the Calendar adjustments
field on the SAP Easy Access
screen under . You can determine if SAP SNC distributes the quantity from a holiday on the previous day, the next day, or proportionally among the
remaining working days.
Note
If the holiday is a Monday, and Saturday and Sunday are defined as non-working days, SAP SNC distributes the quantities from Monday to the next day by default. If the holiday is a Friday, and Saturday and Sunday are defined as non-working days, SAP SNC distributes the quantities from Friday to the previous day by default.
You are using CSF with a factory calendar enabled. Your factory calendar defines Monday to Friday as working days, while Saturday and Sunday are defined as non-working days. You want to release demand data in a weekly bucket for the period of 2010-07-19 to 2010-07-25 (24th of July and 25th of July being the non-working days) with 80 pieces of PRODUCT_A from CSF to short-term forecasting. When CSF releases the demand data, SAP SNC disaggregates it as follows:
Period |
19.07.2010 |
20.07.2010 |
21.07.2010 |
22.07.2010 |

You are using CSF with a factory calendar enabled. Your factory calendar defines Monday to Friday as working days, while Saturday and Sunday are defined as non-working days. In this period, Tuesday is a national holiday and you have set up your calendar adjustments so that SAP SNC distributes the quantity for the holiday proportionally among the remaining working days. You want to release demand data in a weekly bucket for the period of 2010-07-19 to 2010-07-25 (the 20th of July being the holiday while the 24th of July and 25th of July are the non-working days) with 80 pieces of PRODUCT_A from CSF to short-term forecasting. When CSF releases the demand data, SAP SNC disaggregates it as follows:
Period |
19.07.2010 |
20.07.2010 |
