Tracing factor

Hi Friends,

In assessment cycle, if skf is used as tracing factor, how can I see this setting of skf in the cycle?

How does an SKF work?

Is my understanding correct , as described:

1. Canteen is used by 3 departments .

2. Each department has the following number of employees:

Dept A : 10

Dept B : 15

Dept C : 20

Using the above ratio, is cost allocated using skf of employee numbers simply as follows:

Cafeteria cost $1000

Cost allocated to Dept A : [10 / (101520) ] * 1000?

likewise for the rest of departments?

Is it just like what I described above? Kindly confirm for me if I am correct.

regards

Markus
