Copy Key Figure with Disaggregation

Hi experts,

My requirement is to copy KF1 to KF2, where:

- KF1 is defined at a planning level that is more aggregate than the planning level of KF2.

- KF2 would have KF3 as disaggregation key figure.

I want the value from KF1 to be copied to KF2 and disaggregated by KF3

Example:

KF1 is defined at product / location (es: “Statistical Forecast”)

KF2 is defined at product/ location /customer (es: “Forecast disaggregated by Customer”)

KF3 is defined at product/ location /customer (es: “Previous Year sales by Customer”, stored)

My understanding is that Copy Operator could do the copy from KF2 to KF1 (with the prerequisite that the destination KF is stored); but it cannot copy from KF1 to KF2.

Which are the options to cover my requirement?

Thanks,

Patrizia
