Help on File - itab - table problem

Question

Good day!
My problem is this. I am suppose to create an ABAP program that would get the 2 inputs from the user. The table name as well as a filename. My program should be able to transfer the contents from the file to the table in their respective fields. Now, the file is tab-delimited. and I should transfer the contents to the respective tables. The file is I am testing right now has about a 1000 entries so for every 1 row in the file, it is equivalent to the fields in the table. ex.
CoCd     DocumentNo     S     PLSTAT     Period     Reference     ZZGRP     BIZ_TYPE     Doc. Type     Crcy     Document Header Text     Pstng Date     Cre.Date     Last updte
2200     924     1          06     4000013407               ME     AED     INV.7800009952-BL30240499     06/02/2008     06/05/2008     06/05/2008
That's just one entry. It looks messy because it is crammed into this box. but in a text file it is actually per line. My code now looks like this.
REPORT  ZISZT_UPL_PDPL                          .
*DATA DECLARATIONS                                                     *
TABLES: ZISZT_ZPDPLH, ZISZT_ZPDPLD.
PARAMETERS: tble_n(20) TYPE C OBLIGATORY,
            file_n(20) TYPE C OBLIGATORY.
DATA: BEGIN OF zpdplh_tab OCCURS 100.
      INCLUDE STRUCTURE ZISZT_ZPDPLH.
DATA: END OF zpdplh_tab.
DATA: FILE TYPE STRING.
FILE = file_n.
*UPLOAD FILE TO TABLE                                                  *
CALL FUNCTION 'GUI_UPLOAD'
     EXPORTING
         FILENAME               = FILE
         FILETYPE               = 'DAT'
     TABLES
         DATA_TAB               = zpdplh_tab
     EXCEPTIONS
        FILE_OPEN_ERROR         = 1
        FILE_READ_ERROR         = 2
        OTHERS                  = 3.
LOOP AT zpdplh_tab.
  WRITE zpdplh_tab-BUKRS.
ENDLOOP.
The Loop is just to test if my internal table is getting the contents of the file. But it seems that it only gets one line. How do i fix this? Also, am I doing the right thing? Creating an internal table to transfer the files to then I would transfer it to the table in the database. Is this right? Or is there an easier way, I am suppose to transfer its contents to the table inputted by the user. Is there possible to implement some error cehcking here as well? Thanks in advance for the ideas and adivces,

hi there check this ..
DATA: BEGIN OF zpdplh_t OCCURS 100.
INCLUDE STRUCTURE ZISZT_ZPDPLH.
DATA: END OF zpdplh_t.
data: zpdplh_tab type standard table of zpdplh_t.
and one more thing.. gui_upload will not work in background.. so check if it might be an issue later..
CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
FILENAME = PATH
FILETYPE = 'ASC'
HAS_FIELD_SEPARATOR = 'X'
HEADER_LENGTH = 0
TABLES
DATA_TAB = ITAB
EXCEPTIONS
FILE_OPEN_ERROR = 1
FILE_READ_ERROR = 2
NO_BATCH = 3
GUI_REFUSE_FILETRANSFER = 4
INVALID_TYPE = 5
NO_AUTHORITY = 6
UNKNOWN_ERROR = 7
BAD_DATA_FORMAT = 8
HEADER_NOT_ALLOWED = 9
SEPARATOR_NOT_ALLOWED = 10
HEADER_TOO_LONG = 11
UNKNOWN_DP_ERROR = 12
ACCESS_DENIED = 13
DP_OUT_OF_MEMORY = 14
DISK_FULL = 15
DP_TIMEOUT = 16
OTHERS = 17.
