Statistical Key Figure Groups in Assessment Cycles

Dear All,

What is the use of Statistical Key Figure Groups (SKF) in the Assessment Cycle?

My question is that we have one Sender Cost Center and Two Receiver Cost Centers and I have created one SKF (for ex: no of employees) ,based on this I will run the assmt cycle for allocation.This is OK

Then where shall we use the SKF Groups?Kindly share if anybody knows about the use of SKF Groups.

PT Ugent.
