 Phase-In Profile

Definition

Forecast curve that the system creates using historical data of products that are in the same phase-in groups. The system uses this profile to create forecast values for newly introduced products that belong to this phase-in group.

Use

To create a forecast for a new product, you assign a suitable phase-in profile to the new product. To create this phase-in profile, you assign newly introduced products that have a similar sales history to the same phase-in group. Using historical values of these products from the first period, the system then creates a phase-in profile for the phase-in group.

You can define the characteristics of the phase-in groups and the resulting phase-in profile in the IMG activity Phase-in Groups in Customizing for Advanced Planning and Optimization under Start of the navigation path Supply Chain Planning Next navigation step Service Parts Planning (SPP) Next navigation step Forecast End of the navigation path .

Structure

A phase-in profile is defined by the following parameters for phase-in groups:

  • Number of periods that it consists of

  • Maximum number of historical periods that a product may have in order to be considered during the creation of the phase-in profile

  • Minimum number of products that must be available to create a phase-in profile

If there is a large deviation between the historical periods within a group, a phase-in group can consist not just of a standard profile, but also of multiple phase-in profiles. In this case, the phase-in group consists of a profile for high demand, a profile for medium demand, and a profile for low demand. For a profile for high demand, the system calculates the average of the historical data of both products whose historical data shows the highest demand. For a profile for low demand, the system calculates the average of the historical data of both products whose historical data shows the lowest demand. The system calculates a profile for medium demand using the historical data of all other products in the phase-in group. For a system to create several profiles for one phase-in group, the following conditions must be met:

  • There must be a minimum number of products.

  • The deviation between products with low average values and products with medium average values must be greater than a certain minimum variance.

  • The deviation between products with high average values and products with medium average values must be greater than a certain minimum deviation.
