Adding values for a single customer

Question

Hi Everybody,
I am facing a programming issue. I have to do something like this:
For a each customer, for all open items for that customer, I have to add the amount due at every period in aging in Accounts receivable. So for example, if I have two customers: A and B and
A has 5 open items
B has 3 open items
for each open item there is an amount due for both customers. So what i have to do is add for A 1+2 = amount 1.
amount 1 + 3 = amount 2, amount 24 = amount 3, amount 35 = amount 4.
Similarly for B also I have to do the same thing. Right now my amount are getting added up into one single value at each line of the table. So for all customers it is just getting added in every row of the table and not seperately for every new customer.
Can somebody suggest something or give some example?
Please help.
Thanks & regards,
AM

I'm not sure I understand what you are trying to do. Is it something like:
REPORT ztest.
TABLES: bsid.
PARAMETERS p_bukrs LIKE bsid-bukrs.
SELECT-OPTIONS s_kunnr FOR bsid-kunnr.
DATA: BEGIN OF itab OCCURS 0,
        bukrs LIKE bsid-bukrs,
        kunnr LIKE bsid-kunnr,
        under_30_amt LIKE bsid-dmbtr,
        under_60_amt LIKE bsid-dmbtr,
        under_90_amt LIKE bsid-dmbtr,
        over_90_amt  LIKE bsid-dmbtr,
      END   OF itab.
DATA: under_30_date LIKE sy-datum,
      under_60_date LIKE sy-datum,
      under_90_date LIKE sy-datum,
      over_90_date  LIKE sy-datum.
under_30_date = sy-datum - 30.
under_60_date = sy-datum - 60.
under_90_date = sy-datum - 90.
over_90_date  = sy-datum - 30.
SELECT bukrs kunnr bldat dmbtr
  INTO CORRESPONDING FIELDS OF bsid
  FROM bsid
  WHERE bukrs = p_bukrs
    AND kunnr IN s_kunnr.
  CLEAR itab.
  MOVE: bsid-bukrs TO itab-bukrs,
        bsid-kunnr TO itab-kunnr.
  IF bsid-bldat > under_30_date.
    MOVE bsid-dmbtr TO itab-under_30_amt.
  ELSEIF bsid-bldat > under_60_date.
    MOVE bsid-dmbtr TO itab-under_60_amt.
  ELSEIF bsid-bldat > under_90_date.
    MOVE bsid-dmbtr TO itab-under_90_amt.
  ELSE.
    MOVE bsid-dmbtr TO itab-over_90_amt.
  ENDIF.
  COLLECT itab.
ENDSELECT.
LOOP AT itab.
  WRITE: /001 itab-bukrs,
              itab-kunnr,
              itab-under_30_amt,
              itab-under_60_amt,
              itab-under_90_amt,
              itab-over_90_amt.
ENDLOOP.
<i>Caveats</i>
I'm not sure what date you should use for aging. I used the document date. Maybe it's the baseline date. Maybe it's something else.
Collect is inefficient. You might want to do it another way.
I may be way off base - you may be doing something else entirely.
