Upload file in XSTRING format in SE38 report progr...

Former Member · ‎2010 Jun 21

Hi All,

We have a very typical requirement of uploading attachments for Infotype using both Frontend(Web-Dynpro ABAP) and Backend(SE38 report program).

From frontend it is very simple as we directly get the data in XSTRING format. However, from backend I am facing some difficulty in getting data into XSTRING format.

1st I tried using GUI_UPLOAD in BIN mode and it gives me a dump which points to some SAP standard error in transferring data(frankly i donno what is going on there)...Ok.... dump is due to output table type as string. when i change it to char1024 there is no more error but the output data looks like some weird combination of Chinese characters, # and ~.

2nd I tried GUI upload in ASC mode and then convert the text into XSTRING but i donno if the file structure will remain stable by doing so.... (here GUI upload does not give me any dump or error)

3rd - search for similar blogs but failed finding anything which is quite relevant to the requirement.

Here is the code which I used for BIN mode:


DATA: gt_bin_data TYPE STANDARD TABLE OF char1024.
DATA: gd_file_length TYPE i.

CALL FUNCTION 'GUI_UPLOAD'
  EXPORTING
    filename                      = p_file

*   ACCESS_DENIED                 = 13
*   DP_OUT_OF_MEMORY              = 14
*   DISK_FULL                     = 15
*   DP_TIMEOUT                    = 16
*   OTHERS                        = 17
          .
IF sy-subrc <> 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
*         WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
ENDIF.

Any help would be appreciated.

i guess you are uploading some PDF file.. right?

yes.. when it is uploaded with BIN format..it will come in those Chinese and ## type only.. (you try to download the same.. you will find your PDF back)..

you cant read your PDF file data by uploading with GUI_DOWNLOAD.. you need to upload a XML.. then you can use ST to transform data to your required format.

Hi,

Below is the code for the filetype BIN

<gs_upload_wa> TYPE ANY.

gv_tab TYPE REF TO data.

CREATE DATA gv_ref TYPE ty_data_tab_bin.

ASSIGN gv_ref->* TO <gs_upload_wa>.

CREATE DATA gv_tab TYPE TABLE OF ty_data_tab_bin.

ASSIGN gv_tab->* TO <gs_upload_table>.

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

filename = lv_filename_str

FILETYPE = lv_filetype

End UCC

IF sy-subrc <> 0.

RAISE upload_failed.

ENDIF.

Hi,

CREATE DATA gv_ref TYPE ty_data_tab_bin.

ASSIGN gv_ref->* TO <gs_upload_wa>.

CREATE DATA gv_tab TYPE TABLE OF ty_data_tab_bin.

ASSIGN gv_tab->* TO <gs_upload_table>.

what should be the type of "ty_data_tab_bin" in the above code. I tried using table to type string but it dumps.

Regards,

Dileep

"DATA: gt_bin_data TYPE STANDARD TABLE OF char1024."

you have an error in your data declarations. The type should be type table of tbl1024.

after the 'BIN' upload use the SCMS_BINARY_TO_XSTRING function module to convert binary table to xstring....very simple process and flawless for me.

BTW, this has been discussed at length in these forums previously. May I suggest a search before posting in the future....will save you a lot of time, since it is unlikely that you will come across a problem that has not been discussed here previously.

Hey man,

You did not mentioned what type is ty_data_tab_bin and w_data_tab_bin

and data_tab and w_data_tab and in above given code (Sumodh P Jun 21, 2010 11:25 AM).

Copy same code to your sample program you will get plenty of syntax error.

I'm probably late, but there's a solution to this problem. SAP handles the XSTRING, the hexadecimal string, and not the binary string when I try to display content using the various "viewers" available. So the GUI_UPLOAD solution is valid, but the conversion from BINARY to XSTRING is missing. Here's the code:

  DATA filename            TYPE string.
*  DATA FILETYPE            TYPE CHAR10.
*  DATA HAS_FIELD_SEPARATOR TYPE CHAR01.
*  DATA HEADER_LENGTH       TYPE I.
*  DATA READ_BY_LINE        TYPE CHAR01.
*  DATA DAT_MODE            TYPE CHAR01.
*  DATA CODEPAGE            TYPE ABAP_ENCODING.
*  DATA IGNORE_CERR         TYPE ABAP_BOOL.
*  DATA REPLACEMENT         TYPE ABAP_REPL.
*  DATA VIRUS_SCAN_PROFILE  TYPE VSCAN_PROFILE.
  DATA filelength          TYPE i.
*  DATA HEADER              TYPE XSTRING.
  DATA data_tab            TYPE STANDARD TABLE OF tdline.
*  DATA ISSCANPERFORMED     TYPE CHAR01.

  MOVE: url TO filename. "In this example i used variable url that contain the fullpath.
