Sapscript printing only the last value

Question

Hello,
Im currently coding subroutine for medruck.. My problem is sapscript is only printing the last value of the item for all items.. For example:
Item # 1    10 pcs  10,000.00
Item # 2     5 pcs   10,000.00
Item # 3     5 Pad  10,000.00
where actually the value of item 1 and item 2 is not 10,000.. sapscript prints only the price of item # 3 for the  first two items.. here is my code..
  TABLES: konv, ekko, ekpo.
  DATA: BEGIN OF tab OCCURS 0,
      brtwr LIKE ekpo-brtwr,
      ebelp LIKE konv-kposn,
      ebeln LIKE ekko-ebeln,
      knumv LIKE ekko-knumv,
      kbetr LIKE konv-kwert,
END OF tab.
  DATA: sum TYPE p DECIMALS 2, gross TYPE p DECIMALS 2, val(16) TYPE c, d_knumv LIKE ekko-knumv, tab1 LIKE tab, val1(20) TYPE c,
        ext TYPE p DECIMALS 2, val2(20) TYPE c, extend TYPE p DECIMALS 2.
  REFRESH: tab.
  READ TABLE in_tab INDEX 1.
  CHECK sy-subrc = 0.
  SELECT brtwr ebelp ebeln FROM ekpo INTO TABLE tab WHERE ebeln = in_tab-value.
  LOOP AT tab.
    AT NEW ebelp.
      tab-kbetr = 0.
      ext = 0.
    ENDAT.
    SELECT SINGLE knumv FROM ekko INTO tab-knumv WHERE ebeln = tab-ebeln.
    SELECT SINGLE kbetr FROM konv INTO tab-kbetr WHERE knumv = tab-knumv AND kposn = tab-ebelp                                AND kschl = 'ZDEL'.
    ext = tab-brtwr + tab-kbetr.
    AT END OF ebelp.
      READ TABLE out_tab INDEX 1.
      WRITE ext TO val.
      out_tab-value = val.
      MODIFY out_tab INDEX 1.
    ENDAT.
    CLEAR: tab.
  ENDLOOP.
