The parameters such as Seasonal Profiles, Weekly Profiles, Period Profile and Holiday template have to be defined for each flow/part combination to achieve a good system forecast. One way to achive this is to set these parameters for each flow/part combination manually or to manually copy these down from several flow/group combinations down to each individual flow/parts. This approach will demand a lot of manual work if new parts are added to the system. To reduce this manual work involved with setting these parameters, an inheritance model is introduced to determine a parts right profiles (Seasonal Profiles, Weekly Profiles & Period Profile) and holiday template. The Inheritance function means that when a new part is introduced to Demand Planning the part will get Seasonal Profiles, Weekly Profiles, Period Profile and Holiday template inherited based on the group or group combinations that the new parts belongs to.
The most dominant group is Group 1 and which will be followed in descending priority by Group 2, Group 3 Group 4 Group 5 and Group 6 respectively. See Demand Plan Server setup. If you have set up Inheritance ruels for both Group 1 and Group 2, a part that is member of both groups will inherit the profiles set on Group 1, since it has higher rank.
Combined flows as also a rank number connected to them, the flow with the higest rank number will be choosen over a flow with a lower rank number, if both have equaly matching group rules.
Creating inheritance rules can be done either in the Inheritance Rules table or it can be set by selecting the group level you want to be the scource of the inheritance in the Demand Plan Client GUI, and then select the wanted profiles when you push the inheritance button in front of the profiles and set turn the inheritance on you will create an inheritance rule. And all parts that is members of this group setting and that have inheritance on will get this profile inherited down.
