send pdf with web service, using base64 encode

Hi Gurus,

I have a PDF in from a smartform using CONVERT_OTF and i can see pdf with GUI_DOWNLOAD. but i need to send it with base64 format, i used SCMS_BINARY_TO_XSTRING and convert base64 but it doesnt work.

Does anyone have any advice for me?

Regards,

So, you have a bug in your code, but how could we tell you what/where it is.

thank you for answer,

here is my code,

I submit a program in fm,

*** program codes

CALL FUNCTION 'CONVERT_OTF'
EXPORTING
format = 'PDF'
archive_index = archive_index
IMPORTING
bin_filesize = lv_bin_filesize
TABLES
otf = otf-otfdata
lines = it_lines
EXCEPTIONS
err_conv_not_possible = 1.

CALL FUNCTION 'SCMS_BINARY_TO_XSTRING'
EXPORTING
input_length = lv_bin_filesize
IMPORTING
buffer = lv_xstring
TABLES
binary_tab = it_lines
EXCEPTIONS
failed = 1
OTHERS = 2.
IF sy-subrc EQ 0.
gt_py-xspdf = lv_xstring.
APPEND gt_py.
ENDIF.

IF gt_py[] IS NOT INITIAL.
EXPORT gt_py TO SHARED BUFFER indx(st) ID 'ZTEMP'.
ENDIF.

*** function module codes

IMPORT gt_py FROM SHARED BUFFER indx(st) ID 'ZTEMP'.

IF sy-subrc EQ 0.
READ TABLE gt_py INDEX 1.
IF sy-subrc EQ 0.
lv_pdf = gt_py-xspdf.
ENDIF.
ENDIF.

CALL FUNCTION 'SSFC_BASE64_ENCODE'
EXPORTING
bindata = lv_pdf
binleng = lv_length
IMPORTING
b64data = lv_base64
EXCEPTIONS
ssf_krn_error = 1
ssf_krn_noop = 2
ssf_krn_nomemory = 3
ssf_krn_opinv = 4
ssf_krn_input_data_error = 5
ssf_krn_invalid_par = 6
ssf_krn_invalid_parlen = 7
OTHERS = 8.

i cant see lv_base64 like a pdf.

Based on the code you have posted, I can tell:

you export the PDF as a table of fixed-length lines, but you don't export the length in bytes, how can you deduce it when you convert to base 64 (how do you calculate LV_LENGTH?)
why don't you retrieve directly the xstring parameter from CONVERT_OTF, containing the PDF, and exporting it as is.

But I still don't understand why you say "it doesn't work", and "cant see base 64 like a pdf". What do you mean exactly? What did you try? Please give concrete and clear examples, eventually screen shots, etc.

i try to send payslip pdf with web services using base64 format. payslip is calculated a program so i used submit in a function module.

lv_length is not calculated.

the company which use my web service said me 'we decode your webservice value, but it doesnt work'.
