Allocating Plan and Actual Values
Use
Allocating plan values in an actual allocation cycle
Separate allocation cycles are created for plan and actual allocations. In segment definition you can specify that the plan data is allocated in actual instead of the posted actual amounts and actual quantities. To do this, in segment definition select Plan values. Actual amounts and actual quantities are allocated analogous to the plan amounts and plan quantities.

Allocations that have already occurred in the plan are not taken into account.
