Hi Luan
Please check "Automatic Cost Update" Tab from Deployment Optimizer profile. In this tab, you can define priorities for your demand types (Customer Order, Forecast, Safety Stock etc) and also priorities for your Location Products(Class A, B, C).
You define the priority of location products in the location product master data on the SNP 2 tab page. You can enter values from 0 to 255 for the priority. Value 1 is the highest priority. Value 255 is the lowest priority you can enter. No value or value 0 corresponds to priority 256.
Please do read F1 help on those fields.
Thank you
