Allocation - distributing into 12 month

Question

We want to spread the amounts in accounts in P&L on all months of the year in 2 ways: Equally (1) and according to a driver (3).
Equally works fine, according to account DRIVER does not:
*SELECT(%BYEAR%,"[YEAR]",VERSION,"[ID]='BUDGET'")
*XDIM_MEMBERSET PACCOUNT = BAS(ORG_PL)
*XDIM_MEMBERSET TIME = BAS(%BYEAR%.TOTAL)
*WHEN PACCOUNT.PERIODIC
*IS "1"
*RUNALLOCATION
   *FACTOR = 1/12
   *DIM PACCOUNT WHAT=[PERIODIC]= "1";   WHERE=<<<
   *DIM TIME             WHAT=%BYEAR%.12;      WHERE=BAS(%BYEAR%.TOTAL)
*ENDALLOCATION
*ENDWHEN
*WHEN PACCOUNT.PERIODIC
*IS "3"
*RUNALLOCATION
   *FACTOR = USING/TOTAL
   *DIM PACCOUNT WHAT=[PERIODIC]="3"; WHERE=<<<; USING=DRIVER; TOTAL=<<<
   *DIM TIME WHAT=%BYEAR%.12; WHERE= BAS(%BYEAR%.TOTAL); USING= BAS(%BYEAR%.TOTAL); TOTAL=<<<
*ENDALLOCATION
*ENDWHEN
Instead of taking the amount in the individual account with property Periodic = 3, it sums up the amounts of all accounts with the Periodic = 3, allocates with the driver and places the calculated amount per month in all accounts with Periodic = 3 u2013 even those accounts having an amount of 0 to distribute.
When changing WHAT=[PERIODIC]= "3" with the single account, it works fine.

Hi Anne,
You can significantly simplify your script.
First of all, you don't need WHEN/ENDWHEN since you have DIM on PACCOUNT. RUNALLOCATION will select data only from records restricted to that set of members. So, you can safely remove both WHEN/ENDWHEN and check that you have same results.
Now, since you have WHAT, WHERE, USING and TOTAL referring to same set in PACCOUNT you can define same set in XDIM_MEMBERSET and remove it from under RUNALLOCATION.
Different results between equal distribution and proportional are not because proportion is different, but I'd think that you have only 1 account with PACCOUNT.PERIODIC =1. This is how RUNALLOCATION works in NW: it accumulates amounts from all records defined in all WHATs and that distributes them. If you want to distribute each account individually you'd have to put RUNALLOCATION inside a FOR/NEXT loop on accounts.
