Answer 1

actually your are picking up the correct data from Table EKET (EKET-EINDT) but your are printing that in item data loop for EKET might have already executed in your script and the header of that internal table consist the last entry of the table so for that. Fetch the delivery date explicite from the Table EKET when your in item level processing and print that.
For Example u can use this code.
To print you have write the this code in Script item level printing window "MAIN" window
Following perform is called to get the line item delivery date in PO
{/: PERFORM GET_DEL_DATE IN PROGRAM ZPerform_prog
/: USING &EKPO-EBELN&
/: USING &EKPO-EBELP&
/: CHANGING &DEL_DATE&
/: ENDPERFORM}
{* Dellivery date &DEL_DATE& }
write the below code in the Z program "ZPerform_prog"
{ FORM get_del_date  TABLES in_par STRUCTURE itcsy
                         out_par STRUCTURE itcsy.
  READ TABLE in_par WITH KEY 'EKPO-EBELN'.
  CHECK sy-subrc = 0.
  $_po_no = in_par-value.
  READ TABLE in_par WITH KEY 'EKPO-EBELP'.
  CHECK sy-subrc = 0.
  $_po_line = in_par-value.
  SELECT *
  FROM eket UP TO 1 ROWS WHERE ebeln EQ $_po_no AND ebelp EQ $_po_line.
    $_del_date = eket-eindt.
    CALL FUNCTION 'CONVERT_DATE_TO_EXTERNAL'
      EXPORTING
        date_internal            = eket-eindt
      IMPORTING
        date_external            = $_del_date
      EXCEPTIONS
        date_internal_is_invalid = 1
        OTHERS                   = 2.
    READ TABLE out_par WITH KEY 'DEL_DATE'.
    CHECK sy-subrc EQ 0.
    out_par-value = $_del_date.
    MODIFY out_par
                INDEX sy-tabix.
    CLEAR : $_po_no , $_po_line ,$_del_date.
  ENDSELECT.
ENDFORM.                    "GET_DEL_DATE }
