populating ITABs

hai SDNs,

the story is bit lenghty.,,

but could any one pls help me out..

this is my final output table::

(some of the fiedls not all data)

FINAL TABLE:

CIRCLE X CONTRIBUTION PAID EXCESS PAY_DATE

ANP 3 15574 0 15574 0

ANP 9 11600 0 11600 0

HAR 6 316 0 316 0

KER 6 14052 0 14052 0

KOL 6 453.8 0 453.8 0

MAP 6 981 0 981 0

MAP 7 2741 0 2741 0

ORI 6 795.25 0 795.25 0

PUN 7 1310 6608 -5298 20041116

UPE 6 281.8 0 281.8 0

UPW 6 1695.3 0 1695.3 0

HAR 6 0 158 -158 20040930

KER 6 0 7026 -7026 20040930

PUN 6 0 10000 -10000 20040901

check the alignment it is not correct.

now i have populate the 'paid' and 'pay_date' fields from another table having contents:

GSBER MONAT DMBTR BUDAT

HAR 6 316 20040930

KER 6 7026 20040930

PUN 6 10000 20040901

PUN 8 6608 20041116

xyz 1 2200 20040981

here DMBTR = Paid amt and BUDAT = Pay_date(in above table)

so i have to do this based on conditions, checking both table GSBER and circle (in above table) AND monat = x ( in above table)

here :

case 1:

if both business area and monat are equal then modify the record,

other wise append the new record to final table.

so here i did the part of it:

CODE I have written::

<b>----

*case-1

sort lt_bsis by gsber monat.

sort lt_output by circle x.

loop at lt_bsis into lw_bsis.

lf_monat = lw_bsis-monat - 1.

loop at lt_output into lw_output where x = lf_monat and

circle = lw_bsis-gsber.

lw_output-paid = lw_bsis-dmbtr.

lw_output-pay_date = lw_bsis-budat.

if ( lw_output-paid is not initial ) and ( lw_output-pay_date is not initial ).

modify lt_output from lw_output transporting paid pay_date .

endif.

clear: lw_output, lw_bsis .

endloop.

endloop.

----

*case-2

loop at lt_bsis into lw_bsis.

lf_monat = lw_bsis-monat - 1.

if lf_monat = '00'.

lf_monat = '12'.

endif.

loop at lt_output into lw_output where x <> lf_monat and

circle = lw_bsis-gsber.

if sy-subrc = 0.

lw_output_temp-contribution = ' '.

lw_output_temp-paid = lw_bsis-dmbtr.

lw_output_temp-pay_date = lw_bsis-budat.

lw_output_temp-circle = lw_bsis-gsber.

lw_output_temp-x = lw_bsis-monat.

append lw_output_temp to lt_output_temp .

endif.

clear: lw_output_temp, lw_output, lf_monat.

endloop.

endloop.</b>

this is working fine. YOU CAN SEE THIS IN SECOND TABLE.

THERE 3 records are appended and one is modified.

the condition :

where x = lf_monat and circle <> lw_bsis-gsber.

this condition is not working.

i am unable append this particular record satisfying above condition:

<b>xyz 1 2200 20040981 </b>

thanks in advance
