Using field-symbols giving dump " the output area is too small. "

Question

Hi All,
Good Afternoon.
I  am creating a report using field-symbols. The purpose is :
"This development involves extracting all the fields and the entire data, of any SAP table, and download it as a ‘;’ seperator file."
For this I wrote following code:
*& Report  ZTOOL
REPORT  ztool1.
Tables***************************************
DATA : i_tab TYPE TABLE OF dfies WITH HEADER LINE.
Variables***************************************
DATA dref TYPE REF TO data.
FIELD-SYMBOLS <ft> TYPE ANY TABLE." with header line.
FIELD-SYMBOLS <fs> TYPE ANY .
DATA: w_heading(5000),
     w_line(5000).
CONSTANTS  sep TYPE c VALUE ';'.
Selection Screen*********************************
SELECTION-SCREEN BEGIN OF BLOCK b1 WITH FRAME.
PARAMETERS : p_tab LIKE dfies-tabname OBLIGATORY.
PARAMETERS : p_file(100) TYPE c .
PARAMETERS : p_lfile(100) TYPE c .
SELECTION-SCREEN END OF BLOCK b1.
START-OF-SELECTION.
  CALL FUNCTION 'GET_FIELDTAB'
   EXPORTING
     langu                     = sy-langu
  ONLY                      = ' '
     tabname                   = p_tab
  WITHTEXT                  = 'X'
IMPORTING
  HEADER                    =
  RC                        =
    TABLES
      fieldtab                  = i_tab
EXCEPTIONS
   internal_error            = 1
   no_texts_found            = 2
   table_has_no_fields       = 3
   table_not_activ           = 4
   OTHERS                    = 5
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
            WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.
     SELECT * FROM (p_tab) INTO <fs> .       
     endselect.
     CREATE DATA dref TYPE STANDARD TABLE OF (p_tab).
       ENDSELECT.
      assign dref to <fs> casting.
     ASSIGN dref->* TO <ft>.
     SELECT & FROM (p_tab) INTO table <ft>.
     OPEN DATASET p_lfile FOR INPUT IN TEXT MODE ENCODING DEFAULT.
LOOP AT i_tab.
  IF sy-index = 1.
    w_heading = i_tab-fieldname.
  ELSE.
  CONCATENATE w_heading i_tab-fieldname INTO w_heading SEPARATED BY sep.
  ENDIF.
ENDLOOP.
TRANSFER w_heading TO p_lfile.
LOOP AT <ft> into <ft>.
clear w_line.
  LOOP AT i_tab.
         ASSIGN COMPONENT i_tab-fieldname OF STRUCTURE <ft> TO <fs>.
         IF sy-index = 1.
              w_line = <fs> .
         ELSE.
              CONCATENATE w_line <fs> into w_line SEPARATED BY sep.
         ENDIF.
  ENDLOOP.
  TRANSFER w_line TO p_file.
ENDLOOP.
The program is executed well till the statement :
SELECT * FROM (p_tab) INTO <fs> .       
     endselect.
But here it gives the following dump : 
"Error analysis
    In an Open SQL select, the output area used t
    records must be at least as wide as the datab
    records are being read.
    In this particular case, the database table i
    but the output area is only 2 bytes wide."
Can you please help me solve this problem.
Thanks in advance.

Hi Abhii,
Both are having the same number of fields.
The only problem is with the data and time (in my scenario). Here, actual length of date is 8 and maximum length is 10. and for time the actual length is 6 and maximum length is 8.
So, my work area it is taking only the actual length but not the maximum length because of this it is going to dump.
Can i have any thing which also considers the maximum length of any field at a domain level so that by work area bytes should match according to the db table byte length.
Thanks
