confused with the ML actual cost component split logic when CK24

Hi, expert

I was confused with the logic about ML  actual cost component split.  the notes said it should be the same as cost component structure in planning.

I created a new materail,  and made cost estimate for it,  then post the price with ck24.

Bute I found difference exist between cost estimate result (CK13N )and the S price ACCS result( MLCCSPD), why this happens? Can anyone give some guides?
