How to process AT END OF command for company code and transaction number.

Question

Hi,
  I  have report with selection screen with company code and key date.  Based ON key date given I should calculate Accrued interest for all transaction with in each company code.
    When I run report with one company code it works fine. But when I run with multiple company codes the amounts are messed up.
I am getting all company codes with transaction details in to ITAB1 like this below, and PERFORM get_processdata. has my calculation for interest rate.
  SORT itab1 BY company_code  transaction.
  LOOP AT itab1 INTO wa_tab1.
    itab2 = wa_tab1.
    APPEND itab2.
    AT END OF transaction.
       PERFORM get_processdata.
    ENDAT.
  ENDLOOP.
Thank you.

Hello,
You need to use AT New event to clear your total variables.
AT New - this will go for first time also but we want to clear variables from second time. it requires flag to stop going it first time
Pseudo code:
clear: flag.
Loop at itab1 to itab2.
At New.
if flag eq c_x.
clear: <total variables>, intenal tables.
move c_x to flag.
endif.
tab2 = wa_tab1.
APPEND itab2.
AT END OF transaction.
PERFORM get_processdata.
ENDAT.
ENDLOOP.
