Running BAPI_SALESORDER_CHANGE over many orders takes long time

Question

Hi,
I'm using the bapi BAPI_SALESORDER_CHANGE to change orders, and it works well.
I'm using this bapi to change some orders all at once. Therefore I put it into a loop.
When I run my code over all orders that created in one day, it takes about five minutes, but when I run it over all the orders that created during one week, it takes many hours.
Can someone please explain to me what the reason of it and how can I improve it?
Best Regards,
Mohamad.

Hi Prabhu,
When I run the function over about 250 SO it takes some minutes but when run it over about 2000 SO, it takes many hours.
Here is the function that update one order, I use it into a loop, and each step updating one SO.
FUNCTION Update_orders.
  DATA: header_in   LIKE bapisdh1,
            salesdocument LIKE bapivbeln-vbeln,
            header_inx LIKE  bapisdh1x,
            order_item TYPE  bapisditm,
            order_items TYPE TABLE OF bapisditm,
            order_itemx TYPE  bapisditmx,
            order_itemxs TYPE TABLE OF bapisditmx,
            retrn     LIKE bapiret2 
                             OCCURS 0 WITH HEADER LINE,
            pos TYPE posnr_va,
            wa_sales_target TYPE LINE OF ysales_target_table_type.
  REFRESH: order_items, order_itemxs.
  header_inx-updateflag = 'U'.
  LOOP AT sales_target INTO wa_sales_target.
    READ TABLE pos_list INDEX sy-tabix INTO pos.
    CLEAR: order_item, order_itemx.
    order_itemx-itm_number = pos.
    order_itemx-updateflag = 'U'.
    order_itemx-prc_group4 = 'X'.
    APPEND order_itemx TO order_itemxs.
    order_item-itm_number = pos.
    order_item-prc_group4 = wa_sales_target.
    APPEND order_item TO order_items.
  ENDLOOP.
  CALL FUNCTION 'BAPI_SALESORDER_CHANGE'
       EXPORTING
            salesdocument    = salesdocument
            order_header_inx = header_inx
       TABLES
            order_item_in    = order_items
            order_item_inx   = order_itemxs
            return           = retrn.
  CALL FUNCTION 'BAPI_TRANSACTION_COMMIT'.
ENDFUNCTION.
