How to optimize GUI_DOWNLOAD function I am using...

[Former Member]

Hi,

I have got 54 internal tables populated at the end of the report.

I am using GUI_DOWNLOAD Function to download the data in flat files each corresponding to one internal table.

Now in GUI_DOWNLOAD Function, I know I have to mention name of file and name of table as follows:

CALL FUNCTION 'GUI_DOWNLOAD'

EXPORTING

• BIN_FILESIZE =

FILENAME = filenam

WRITE_FIELD_SEPARATOR = ' '

• FILETYPE = 'ASC'

• APPEND = ' '

TABLES

DATA_TAB = ITAB1.

Now I do not want to code GUI_DOWNLOAD 54 times since there are 54 internal tables and I have to mention the name of table always in DAT_TAB parameter.

How can I achieve this ?

You can simply wrap the GUI_DOWNLOAD into a subroutine(FORM) and call this FORM over and over.

form download tables itab
                      using file_name type string.

CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
* BIN_FILESIZE =
FILENAME = file_name
WRITE_FIELD_SEPARATOR = ' '
* FILETYPE = 'ASC'
* APPEND = ' '
TABLES
DATA_TAB = ITAB.


endform.

Now just call this FORM with the parameters.

perform download tables itab1
                        using file_name1.

perform download tables itab2
                        using file_name2.


perform download tables itab3
                        using file_name3.

Or you could use a macro.

define macro_download.

CALL FUNCTION 'GUI_DOWNLOAD'
EXPORTING
* BIN_FILESIZE =
FILENAME = &1
WRITE_FIELD_SEPARATOR = ' '
* FILETYPE = 'ASC'
* APPEND = ' '
TABLES
DATA_TAB = &2.
 
 
end-of-definition.

Then simply call it like so. I think this will work when passing an internal table.

macro_download file1 itab1[].
macro_download file2 itab2[].
macro_download file3 itab3[].
macro_download file4 itab4[].

But I stuck here:

IF PTRVTGPER[] IS NOT INITIAL.

Concatenate '
bma-files-06\redirectedfolders$\tushar.shah\Desktop\TREATY_TABLE_DATA\' 'PTRVTGPER.txt' into FNAME.

perform download tables PTRVTGPER

using FNAME.

ENDIF.

I don't want to put 'PTRVTGPER.txt' in concatenate function, I want that name to be dynamcially taken when I am doing concatenation of string after initial check of internal table ?????

[RichHeilman]

Ok, if you path is constant, then just pass the filename and concatenate inside the FORM.

[code]IF PTRVTGPER[] IS NOT INITIAL.

fname = 'ptrvtgper.txt'.

perform download tables PTRVTGPER

using FNAME.

ENDIF.

form download tables itab using fname type string.

Concatenate '
bma-files-06\redirectedfolders$\tushar.shah\Desktop\TREATY_TABLE_DATA\' fname

into FNAME.

.....

Endform.[/code]

Hi,

Probably have three parameters for the subroutine..

perform download tables PTRVTGPER

<b>* Folder - File path</b>

using 'Concatenate '
bma-files-06\redirectedfolders$\tushar.shah\Desktop\TREATY_TABLE_DATA\'

<b>* File name</b>

'PTRVTGPER.txt'.

FORM download tables itab

using folder

fname.

IF NOT ITAB[] IS INITIAL.

<b> Concatenate folder fname INTO fname.</b>

• Call the FM GUI_DOWNLOAD..

ENDIF.

ENDFORM.

Is this what you want??

Thanks,

No, I think I am trying to be too much ambitious. I wanted the name of the internal table to get populated in the .txt name and I don't have to write it. I was trying to do this because I have 54 internal tables, hence if I do the way you guys are suggesting then I have to mention name of the internal tables 54 timesbecause I ma using the name of internal table as file name, every time i concatenate....

Hi,

As mentioned pass the internal table name in the subroutine parameter..

Thanks,
