Download more files in bsp application

[Former Member]

Hi to all,

i'm developing a new bsp  and i need to download more files;

for download file i use this method:  CALL METHOD cl_bsp_utility=>download

1.Convert the text to a text table ie Internal table with a line type char255 or some others.

2.Convert the text table into a string.

3.Convert the string to XSTRING.

4.Download that XSTRING as text file using the method

   CL_BSP_UTILITY=>download.

if I download 1 file  its all ok but     if I try to download 2 files on click button the system  always download the latest;

why?...how can I download 2 or more files on click button?

regard.

Maybe creating a single zip file containing the two files you want to download would provide a better solution. For example:

DATA: lr_zip          TYPE REF TO cl_abap_zip,
          lv_xstring   TYPE xstring.
    data: lv_zip_xstring  TYPE xstring.
    CREATE OBJECT lr_zip. "Create instance of Zip Class

*File 1 content in string lv_string1

CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
      EXPORTING
        text     = lv_string1
        mimetype = 'APPLICATION/MSEXCEL;charset=utf-16le'
      IMPORTING
        buffer   = lv_xstring.

    lr_zip->add(  name    = 'File1.xls'
                  content = lv_xstring ).

*File 2 content in string lv_string2
CALL FUNCTION 'SCMS_STRING_TO_XSTRING'
      EXPORTING
        text     = lv_string2
        mimetype = 'APPLICATION/MSEXCEL;charset=utf-16le'
      IMPORTING
        buffer   = lv_xstring.

    lr_zip->add(  name    = 'File2.xls'
                  content = lv_xstring ).
*   Get the binary stream for ZIP file
     lv_zip_xstring = lr_zip->save( ).

    IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
    ENDIF.
    lv_app_type = 'APPLICATION/zip'.
    CALL METHOD cl_bsp_utility=>download
      EXPORTING
        object_s            = lv_zip_xstring
        content_type        = lv_app_type
        content_disposition = 'attachment;filename=File.zip'
        response            = runtime->server->response
        navigation          = navigation.

Hi Jamie,

thanks for your response;

this solution is no good for me because i need of two files ( not zipped) ....i haven't idea.

Another questions......how to reload bsp after download file?..I have tried everything but without success.

Not sure how a serious requirement can reject a zipped file solution to this problem as the end user gets all the file in the end just the same, especially since you've had this issue open for months.

Also, I think what you are asking for might be outside the standard  browser capabilities although there are a few work arounds suggested in this thread:

Are you giving a different file names to your second download in parameter content_disposition? E.g.

*first file

CALL METHOD cl_bsp_utility=>download
               EXPORTING
                 object_s            = lv_xstring
                 content_type        = lv_app_type
                 content_disposition = 'attachment;filename=File1.xls'
                 response            = runtime->server->response
                 navigation          = navigation.

*second file

CALL METHOD cl_bsp_utility=>download
               EXPORTING
                 object_s            = lv_xstring
                 content_type        = lv_app_type
                 content_disposition = 'attachment;filename=File2.xls'
                 response            = runtime->server->response
                 navigation          = navigation.

Hello Swb,

I'm afraid that my last suggestion won't work. In fact, I don't think this method can be used to down load multiple files in one server round trip as it uses the http response to instruct the browser to start downloading and so as you have been finding if you call it twice in one server round trip the first call is overwritten with the second. You could always try to force this method my by having two server round trips - trigger a second event after the first call to this method  so that the second download start as soon as the page has reloaded.

Not user what you mean by reload BSP, the page should reload after each server round trip. If you mean return to some initial state you will have to program this yourself.

I'll try and offer some more constructive suggestions about this issue if I get a chance.

Points are always appreciated if you find a suggestion helpful.

Hi swb,

You may use GET_WITH_TABLE or GET_WITH_FILE or GET_WITH_URL methods of class CL_CRM_DOCUMENTS. For single file i used GET_WITH_URL method but for multiple files u can use loop.

And for uploading files we had used same class method (CREATE_WITH_TABLE).
