Adding Header to a TEXT File

[Former Member]

Hi All,

I am downloading some data into a text file using GUI_DOWNLOAD FM.

Is there any way that i can add a header line on top of the file? In excel file, it is possible, but how do i do it for a *.txt file?

hi..

add filetype also

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

filename = f_name " a variable to hold file name

filetype = 'ASC'

Try changing the file type to DAT. Also make sure HAS_FIELD_SEPARATOR parameter is checked

Hello,

Check this.

* Headings: TEXT-U01 ... TEXT-U28
    DO 28 TIMES.
      CLEAR: L_F_INDEX,L_F_NAME,L_F_HEADERS.
      L_F_INDEX = SY-INDEX.
      CONCATENATE 'TEXT-U' L_F_INDEX INTO L_F_NAME.
      ASSIGN (L_F_NAME) TO <FS_HEADER>.
      L_F_HEADERS = <FS_HEADER>.
      APPEND L_F_HEADERS TO L_T_HEADERS.
    ENDDO.

    CALL FUNCTION 'WS_DOWNLOAD'
         EXPORTING
              FILENAME                = SP_FILE
              FILETYPE                = 'DAT'
         TABLES
              DATA_TAB                = L_T_OUT
              FIELDNAMES              = L_T_HEADERS " Check Here
         EXCEPTIONS

Hi Abhijit,

You can follow the following approach:-

Let your data is in ITAB which u want to download to front end.

1) Create a data set using OPEN DATASET

2)Transfer text DATASET.

3) LOOP AT ITAB.

TRANSFER ITAB to DATASET.

ENDLOOP.

Now your data with header is in Application Server.

4) Now you use the transaction CG3Y and transfer data from App. Server to Presentation Server.

Hi Abhijith,

The below code is to download a CSV txt file. If u want u can get the excel file also by just changing the extension from .txt to .exl Try in the way given below. U will be able to insert the required header too and get the excel file also.

FORM gui_download.

*--Local data declaration

DATA : l_count TYPE i,

l_filename TYPE string.

FIELD-SYMBOLS: <fs_download>.

*--Count the number of fields

DO.

ASSIGN COMPONENT sy-index OF STRUCTURE wa_inputtab TO <fs_download>.

IF sy-subrc <> 0.

EXIT.

ELSE.

l_count = l_count + 1.

ENDIF.

ENDDO.

CLEAR wa_inputtab.

*--Inserting the fields to the internal table in the required format

LOOP AT inputtab INTO wa_inputtab.

DO l_count TIMES. " Adding the delimiter in required places

ASSIGN COMPONENT sy-index OF STRUCTURE wa_inputtab TO

<fs_download>.

CONCATENATE wa_csv_output ',' <fs_download> INTO wa_csv_output.

ENDDO.

SHIFT wa_csv_output.

APPEND wa_csv_output TO itab_csv_output.

CLEAR wa_csv_output.

ENDLOOP.

*--Inserting the header to the internal table.

CONCATENATE 'DTAFF#' 'DTPRAC' 'DTPPP' 'DTREP' 'DTCURR' 'DTNATL'

'DTLAMT' 'DTFMD' 'DT$AMT' 'DTUNIT' 'DTRATE'

INTO wa_csv_output SEPARATED BY ','.

INSERT wa_csv_output INTO itab_csv_output INDEX 1.

IF NOT itab_csv_output[] IS INITIAL.

*--Download Data

l_filename = p_output.

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

filename = l_filename

filetype = 'ASC'

has_field_separator = 'X'

TABLES

data_tab = itab_csv_output

EXCEPTIONS

file_open_error = 1

gui_refuse_filetransfer = 4

invalid_type = 5

no_authority = 6

unknown_error = 7
