Carrying some calculations in ABAP

Question

Dear Friends,
We are having two ztables. One table which is quantity table is hving fields Co Code, Bus Area, Item & Quantity. In this table mainly Items are of 4 types. In the other ztable which is rates table we are having fields like Year, Product 1, Product 2, Product 3, Product4 , Product 5, Product 6 in which we are maintaing rates.
Now, we want if the Itam is like Product 1 then it should take the quantity from the table 1 for that particular combination of Co Code & Bus Area then multiply it with the unit rate given in othr table.
Plz guide me in this in writing the code.
Thanx

Hi Nishu,
You can execute this code.
REPORT zkun_sdntable .
TABLES: zkun_quanttab, zkun_ratetab.
DATA: BEGIN OF itab1 OCCURS 0.
        INCLUDE STRUCTURE zkun_quanttab.
DATA: END OF itab1.
DATA: BEGIN OF itab2 OCCURS 0.
        INCLUDE STRUCTURE zkun_ratetab.
DATA: END OF itab2.
DATA : val TYPE zkun_quanttab-my_qty,
       rate TYPE zkun_ratetab-p1.
DATA : BEGIN OF itab3 OCCURS 0,
       value TYPE zkun_quanttab-my_qty,
       my_ccode TYPE zkun_quanttab-my_ccode,
       my_barea  TYPE zkun_quanttab-my_barea,
       my_item TYPE zkun_quanttab-my_item,
       my_year TYPE zkun_ratetab-my_year,
       END OF itab3.
SELECT * FROM zkun_quanttab INTO TABLE itab1.
SELECT * FROM zkun_ratetab INTO TABLE itab2.
val = 0.
rate = 0.
LOOP AT itab1.
  LOOP AT itab2.
    CASE itab1-my_item.
      WHEN 'P1'.
        rate = itab2-p1.
      WHEN 'P2'.
        rate = itab2-p2.
    ENDCASE.
    val = val +  rate * itab1-my_qty.
  ENDLOOP.
  itab3-value = val.
  itab3-my_ccode = itab1-my_ccode.
  itab3-my_barea = itab1-my_barea.
  itab3-my_item = itab1-my_item.
  itab3-my_year = itab2-my_year.
  APPEND itab3.
  val = 0.
ENDLOOP.
LOOP AT itab3.
WRITE : / itab3-my_ccode, itab3-my_barea, itab3-my_year , itab3-my_item,
    itab3-value.
ENDLOOP.
Hope this solves your query.
Regards,
Kunal.
Note :
The structure of table <b>zkun_quanttab</b> contains
my_ccode for company code, my_barea for business area, my_item for item and my_qty for quantity.
The structure of table <b>zkun_ratetab</b> contains
my_year for year, p1 for product1, p2 for product2 etc.
