Issue with select query join....

Question

Hello,
I am facing a problem with a select query. I get a message that itab_data is not long enough.
DATA: itab_data like ptrv_head occurs 0 with header line.
SELECT *    from PTRV_HEAD
            as a inner join PA0002 as b
            on a~pernr = b~pernr
            inner join PA0001 as c
            on a~pernr = c~pernr
            INTO TABLE itab_data
       where a~PERNR in S_PERNR
       and   a~REINR in S_TRIP
       and   a~ZLAND in S_LAND
       and   a~DATV1 in S_BEGIN
       and   a~DATB1 in S_END
       and   b~NACHN in S_FIRST
       and   b~VORNA in S_LAST
       and   c~BUKRS in S_BUKRS
       and   c~KOSTL in S_KOSTL
       and   c~PERSG in S_EMPGP
       and   c~PERSK in S_SUBGP
       and   c~begda in ldbbegda
       and   c~endda in ldbendda.
Regards,
Jainam.

Hi,
Try this..
DATA: t_dfies  TYPE STANDARD TABLE OF dfies.
DATA: t_fields TYPE STANDARD TABLE OF char40.
DATA: s_dfies  TYPE dfies,
      s_fields TYPE char40.
* Get the fields
CALL FUNCTION 'DDIF_FIELDINFO_GET'
  EXPORTING
    tabname        = 'PTRV_HEAD'
  TABLES
    dfies_tab      = t_dfies[]
  EXCEPTIONS
    not_found      = 1
    internal_error = 2
    OTHERS         = 3.
IF sy-subrc <> 0.
  MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
          WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.
* Build the fields to be selected.
LOOP AT t_dfies INTO s_dfies.
  CONCATENATE 'A~' s_dfies-fieldname INTO s_fields.
  APPEND s_fields TO t_fields.
  CLEAR: s_fields.
ENDLOOP.
* Select.
SELECT (t_fields)    from PTRV_HEAD
