Using aggregation in ABAP code for internal table

Question

I have written following code to get cumulative amount on a date but i have to hit database for each record.
Can't I use some function similar to SUM for doing the same thing on internal table??It would increase my performance.
code is:
    SELECT SUM( DEB_CRE_LC ) FROM /BIC/AZFIAR_O500
     INTO LV_BALMONTH   WHERE   DEBITOR = LV_DEBITOR AND
    CALMONTH GE LV_STARTMONTH AND CALMONTH  LE LV_LASTCALMON.
I want to put  ZFIAR data to internal table and read and do SUM thing..is it possible?? withotut usiong loop.
regards,

Hi Rajesh,
types : begin of ty_tab,
            date type dats,
            DEB_CRE_LC   type .....     " delare type & is the filed need to summerized
            end of ty_tab,
data: itab type standard table of ty_tab.
SELECT date
              SUM( DEB_CRE_LC )  as DEB_CRE_LC  FROM /BIC/AZFIAR_O500
              INTO corresponding fields of itab
              where CALMONTH GE LV_STARTMONTH AND CALMONTH LE LV_LASTCALMON
              group by date.   " date is the field available in your ODS/transparent table
simulate the above code in your program...
Hope this will work..
