Showing Key figure total on detail from Higher Level

HI,

please see following scenario.

PROD = Product

PRODGROUP = Product Group  (Products roll up to Product Group)

Planning Levels:

PL1 = Period Prod

PL2 = Period Prodgroup

Key Figures:

KF1@PL1 = Stored

KF2@PL2 = Stored

1)   Can i display following in Excel  (without using EPM formatting).  Basically trying to show a total product group value for each product, and what percent that is of product group total

                      Period 1                                                                         Period 2 etc...

Prod1             KF1@PL1  ,    KF2@PL2     ,    KF1@PL1 / KF2@PL2     KF1@PL1      KF2@PL2   etc. 

Prod2             KF1@PL1  ,     KF2@PL2    ,     KF1@PL1 / KF2@PL2     KF1@PL1      KF2@PL2   etc.         

Prod3             KF1@PL1  ,    KF2@PL2     ,    KF1@PL1 / KF2@PL2     KF1@PL1      KF2@PL2   etc.        

etc.

I am trying this with a approach similar to split factor caluclation but calculation KF1@PL1 / KF2@PL2 is always blank (not a null issue is most cases)

2) If this is possible,  does KF1@PL1 and KF2@PL2 have to be stored.  Can either or both of these need to be caluclated?

Thanks!
