filename = 'c:/data.txt'

FILETYPE = 'ASC'

• APPEND = ' '

WRITE_FIELD_SEPARATOR = 'X'

HEADER = '00'----

---

>wanna know whether i can use this to give a header line. what exactly does paramter mean and what r the available options.

• TRUNC_TRAILING_BLANKS = ' '

• WRITE_LF = 'X'

• COL_SELECT = ' '

• COL_SELECT_MASK = ' '

• DAT_MODE = ' '

• CONFIRM_OVERWRITE = ' '

• NO_AUTH_CHECK = ' '

• CODEPAGE = ' '

• IGNORE_CERR = ABAP_TRUE

• REPLACEMENT = '#'

• WRITE_BOM = ' '

• TRUNC_TRAILING_BLANKS_EOL = 'X'

tables

data_tab = i_chqs.

Thanks A lot.

Hi

You can use HEADER parameter only for BINARY file (so not ASCII): it's used to indicate informations like code page.

The particular parameter is not for header but there is another table parameter for Fileheader, but it works only for filetype DBF.

if you want to have header for your columns, first call gui_download with just the header and then call gui_download again with parameter APPEND= 'X' and data table to the same file

Dear Santosh,

'Header' parameter in FM 'GUI_DOWNLOAD' is not meant for inserting a table header, rather 'this parameter enables you to place individual bytes in front of data in the case of a binary download'.

To put the header line in download table, you have 2 options.

1. If your file type is 'DBF', use parameter 'FIELDNAMES'.

2. What I use commonly to enter columnnames in internal table is like this.

types : begin of ztype,

dat1(10) TYPE c,

dat2(15) TYPE c,

dat3(10) TYPE c,

dat4(15) TYPE c,

end of ztype.

data : itab type standard table of ztype,

wa type ztype.

wa-dat1 = 'Test1'.

wa-dat2 = 'Test2'.

wa-dat3 = 'Test3'.

wa-dat4 = 'Test4'.

INSERT wa INTO itab INDEX 1.

call FM 'GUI_DOWNLOAD' with data_tab = itab

Hope this solves your problem.

Regards.
