How to tally P&L YTD data with R/3

Question

Dear Friends,
Daily we are loading data 0FI_GL_4 data source to GL cube.
In GL two types accounts available.
1.Balance sheet items.
2.P&L items.
Balcne sheet items allways carry foward the last years balacne.So my closing balance is tallying with R/3
But in P&L end of the year R/3 side they close all items with 0 amount. In BW  there is no machanisam for 0 amount.
so in bw side last year closing balnce is carry foward the current year opening balance.Here closing balance is not tallying with R/3.
Here users requried YTD of P&L items.
For example: Balance sheet Account 800040 last year March-09 closing balance is 20,000.And current year APR-09 =2000010000-5000 (opening balcnedebit-credit) 25000 is closing balance of apr-09 i.e in balance sheet.
But P&L Account 900000 last year March-09 closing balance is 20,000.this closing balance is not carry fowred into current year.i.e in R/3 it is 0 amount.But in bw it shows 20000. accourding to formula APR-09 =2000010000-5000 (opening balcnedebit-credit) 25000 iam getting in BW report..But Accourding to P&L Actual amount is Apr-09= 0+10000-5000 = 5000 apr-09 clsoing balance have get in BW.
Any idea about P&L tallying with R/3

Dear Dennis,
What your saying that is right.
Our data is updated by all periods including 13 to 16 periods.
but p&l data is not following into bw with 0 amount.
Because in R/3 thay update manually all p&l items to 0 amount.And transfer to retained earnings.
Is there any setting in r/3 side to update 0 amount in BW?At the end of the year only.
