From
F1:
Reservation
This is a reservation. Usually, the user has reserved this item for the order
Tracking
The program has allocated the supply for this demand. The system only tracks if the Tracking Policy field on the item card is set to Tracking Only or Tracking & Action Msg., or during planning in the planning worksheet.
Surplus
Surplus occurs in connection with tracking, for example, if the supply is not allocated to any demand, or the demand is not allocated to any supply.
Prospect
Used for non-order network entities, e.g. item journal line, to carry item tracking.
