Actual or plan activity as var portion type in cylce

Question

hi,
i see in receiver tracing factor in cycle, there is a variable portion type actual activity and plan activity.
May I know what is the use if we choose actual activity or plan activity because normally we are using SKF.
For AT, normally it is fixed where rate in kp46 and quantity in kb21n.
may i know if there is actual or plan activity in cycle receiver tracing factor, how can it work? i mean where to define the rate and quantity?
thanks

Answer 1

Variable portions indicate that the tracing factors are determined automatically from the totals record file. You define the criteria for this database access in the    Tracing Factor screen.
As an example,   Sender A distributes $100,000 to three receivers. The tracing factors are the actual costs.
   Receiver             Cost Element         Amount
   B                    430000               $2000
   C                    430000               $1000
   D                    430000               $2000
       Total       $5000
       The SAP system calculates the following values:
       Receiver B: 100,000/5000 X 2000 = $40,000
       Receiver C: 100,000/5000 X 1000 = $20,000     
       Receiver D: 100,000/5000 X 2000 = $40,000
Actual consumption is also similar to above, in the sense that it reads the value in cost elements of the receivers objects. Whereas actual activity will make the tracing factor to read the values posted in the activity types.
You can see the Receiving tracing factor change as you change the type.
