Get z table data to internal table

Question

hi friends,
when i'm trying to get ztable data to an internal table and run the smartform it's giving a runtime error saying
"In the function module interface, you can specify only fields of a specific type and length under "ITAB".
Although the currently specified field "IT_ZPPR2" is the correct type, its length is incorrect."
here is my se38 code
REPORT  ZPPR_2.
TYPE-POOLS: SLIS.
TABLES : MAST, STPO, ZPPR2.
DATA ITAB LIKE ZPPR2 OCCURS 0 WITH HEADER LINE.
TYPES : BEGIN OF TY_FINAL,
  WERKS TYPE ZPPR2-WERKS, "PLANT
  MATNR TYPE ZPPR2-MATNR, "MATERIAL
  MENGE TYPE ZPPR2-MENGE, "QTY
END OF TY_FINAL.
DATA : IT_ZPPR2 TYPE TABLE OF TY_FINAL WITH HEADER LINE,
       WA_ZPPR2 TYPE TY_FINAL.
START-OF-SELECTION.
SELECT * FROM ZPPR2
  INTO CORRESPONDING FIELDS OF TABLE IT_ZPPR2.
CALL FUNCTION '/1BCDWB/SF00000081'
* EXPORTING
*   ARCHIVE_INDEX              =
*   ARCHIVE_INDEX_TAB          =
*   ARCHIVE_PARAMETERS         =
*   CONTROL_PARAMETERS         =
*   MAIL_APPL_OBJ              =
*   MAIL_RECIPIENT             =

    ITAB                       = IT_ZPPR2
* EXCEPTIONS
*   FORMATTING_ERROR           = 1
*   INTERNAL_ERROR             = 2
*   SEND_ERROR                 = 3
*   USER_CANCELED              = 4
*   OTHERS                     = 5
IF SY-SUBRC <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO

ENDIF.

Hi,
In smartform you have declared as below,
yes, like this
ITAB LIKE ZPPR2
under Tables tab in Form Interface
Then why in program,
TYPES : BEGIN OF TY_FINAL,
  WERKS TYPE ZPPR2-WERKS, "PLANT
  MATNR TYPE ZPPR2-MATNR, "MATERIAL
  MENGE TYPE ZPPR2-MENGE, "QTY
END OF TY_FINAL.
DATA : IT_ZPPR2 TYPE TABLE OF TY_FINAL WITH HEADER LINE,
       WA_ZPPR2 TYPE TY_FINAL.
declare IT_ZPPR2 same in program and smartform both.
declare in program as,
DATA : IT_ZPPR2 type table of ZPPR2 ,
       WA_ZPPR2 TYPE zpr2.
Hope above will solve your problem.
