Try this:.
In Z_PROGRAM use function
..PERFORM get_data_from_z_program in Y_PROGRAM.
In Y_PROGRAM write:
FIELD-SYMBOLS: <qals>. (example for qals table)
* inspection lot data
DATA: t_qals LIKE qals OCCURS 0 WITH HEADER LINE.
DATA: wa_qals LIKE LINE OF t_qals.
   ASSIGN ('(Z_PROGRAM)QALS[]') TO <qals>.
   IF NOT ( <qals> IS INITIAL ) .
     t_qals[] = <qals>.
     READ TABLE t_qals INTO wa_qals INDEX 1.
     IF sy-subrc = 0.
       qals = wa_qals.
     ENDIF.
   ENDIF.
