Hi Babbalsingh,

You can write code as follows:

OPEN DATASET v_file1 IN TEXT MODE FOR OUTPUT ENCODING DEFAULT IGNORING CONVERSION ERRORS.

LOOP AT it_gr_data1 INTO wa_gr_data1.

TRANSFER wa_gr_data1 TO v_file1.

CLEAR wa_gr_data1.

******Here you can do your processing.

ENDLOOP.

CLOSE DATASET v_file1.

HI,

Please try the following


*open file in read mode to get data 
  OPEN DATASET l_file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
  IF sy-subrc <> 0.
    WRITE :'Invalid filename'.
  ELSE.
    DO.
       READ DATASET l_file into wa
         IF sy-subrc <> 0.
           EXIT.
        ENDIF.
        APPEND WA TO ITAB.
   ENDDO.
  ENDIF.
  CLOSE DATASET l_file.
  WRITE:/ 'FILE UPLOADED TO THE PATH', l_file.

wa is the workarea where the data from the file is placed in every do loop pass and it is added to the internal table IT.

Hope this helps

Regards,

Sachin

Hi,

If we want to save the internal table data to the application server

DATA: gdf_filepath type dxfile-filename

DATA: gdt_data type table of gts_data.

DATA: ldf_length type i.

FIELD-SYMBOLS: <lfs_outfile> TYPE gts_data

START-OF-SELECTION.

gdf_filepath = 'C:\mydata.txt'

OPEN DATASET gdf_filepath FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

LOOP AT prt_data ASSIGNING <lfs_outfile>.

DESCRIBE FIELD <lfs_outfile> LENGTH ldf_length IN BYTE MODE.

TRANSFER <lfs_outfile> TO prf_file LENGTH ldf_length.

ENDLOOP.

CLOSE DATASET gdf_filepath.

If we want to save the internal table data to the application server

PARAMETERS p_file TYPE dxfile-filename.

START-OF-SELECTION.

OPEN DATASET p_file IN TEXT MODE ENCODING DEFAULT FOR INPUT.

DO.

READ DATASET p_file INTO gds_data.

IF sy-subrc <> 0.

EXIT.

ENDIF.

APPEND gds_data TO gdt_data.

ENDDO.

CLOSE DATASET p_file.

For the file data which has tab separator between field columns.

DATA: gds_field_split type gts_data.

FIELD-SYMBOLS: <fs_field> TYPE gts_data.

PARAMETERS p_file TYPE dxfile-filename.

START-OF-SELECTION.

OPEN DATASET prf_file IN TEXT MODE ENCODING DEFAULT FOR INPUT.

DO.

READ DATASET p_file INTO gds_field.

SPLIT gds_field AT cl_abap_char_utilities=>horizontal_tab

INTO TABLE gdt_field_split.

LOOP AT gdt_field_split into gds_field_split.

gdf_index = gdf_index + 1.

ASSIGN COMPONENT gdf_index OF STRUCTURE

gds_data to <fs_field>.

IF sy-subrc = 0.

<fs_field> = gds_field_split.

ENDIF.

ENDLOOP.

APPEND gds_data TO gdt_data.

ENDDO.

CLOSE DATASET p_file.

Thanks & Regards

Hi,

You can use this function module /SAPDMC/LSM_F4_SERVER_FILE for F4 help for application server file and then you can use the function module TEXT_CONVERT_XLS_TO_SAP to read data into internal table.

Thanks.
