Question

is there any function module to find total price for delivery no.

Answer 1

If you want to add tax, ... conditions, you could try to read conditions (good luck).
here it's a sample code for sales order (the table are different, but the function the same)
  DATA : is_vbak TYPE vbak ,
         is_vbap TYPE vbap .
* Check if the sales order exist.
  SELECT SINGLE *
         INTO is_vbak
         FROM vbak
         WHERE vbeln EQ vbeln.
  IF sy-subrc NE space.
    RAISE sales_order_unknown.
  ENDIF.
* Check if the sales order item exist.
  SELECT SINGLE *
         INTO is_vbap
         FROM vbap
         WHERE vbeln EQ vbeln
         AND   posnr EQ posnr.
  IF sy-subrc NE space.
    RAISE sales_order_item_unknown.
  ENDIF.
* Set data.
  MOVE : is_vbak-mandt    TO isg_komk-mandt ,
         is_vbak-kalsm    TO isg_komk-kalsm ,
         is_vbak-fkara    TO isg_komk-fkart ,
         'V'              TO isg_komk-kappl ,
         is_vbak-waerk    TO isg_komk-waerk ,
         is_vbak-knumv    TO isg_komk-knumv ,
         is_vbak-vbtyp    TO isg_komk-vbtyp ,
         is_vbak-bukrs_vf TO isg_komk-bukrs ,
         is_vbak-vbeln    TO isg_komk-belnr ,
         is_vbap-posnr    TO isg_komp-kposn .
  MOVE-CORRESPONDING : is_vbak TO isg_komk ,
                       is_vbap TO isg_komp.
* Get the KOMV table.
  CALL FUNCTION 'RV_PRICE_PRINT_ITEM'
    EXPORTING
      comm_head_i = isg_komk
      comm_item_i = isg_komp
    TABLES
      tkomv       = itg_komv
      tkomvd      = itg_komvd.
* Get the 'Marge'.
  CALL FUNCTION 'PRICING_BUILD_XKOMV'
    EXPORTING
      i_komk           = isg_komk
      i_komp           = isg_komp
      calculation_type = 'E'
    TABLES
      tkomv            = itg_komv
      e_xkomv          = itg_komv2
    EXCEPTIONS
      OTHERS           = 2.
