Base64 encoding not recognized

Former Member — Thu, 29 Sep 2016 08:32:43 GMT

Hi Gurus,

We are building Interface with Ariba using web service method. Requirement from Ariba is SAP needs to send 5 files then zipped it and encode it into base64 format.

Below is my code snipet .

DATA lv_contents TYPE arbfnd_attachment_content,

Do 5 times.

OPEN DATASET gv_file FOR INPUT IN BINARY MODE.

IF sy-subrc EQ 0.

DO.

READ DATASET gv_file INTO lv_xstring.

IF sy-subrc EQ 0.

EXIT.

ENDIF.

ENDDO.

ENDIF.

CLOSE DATASET gv_file.

DATA: lv_filename TYPE string.

lv_filename = p_filename.

CALL METHOD go_zipper->add

EXPORTING

name = lv_filename

content = lv_xstring.

Enddo.

CALL METHOD go_zipper->save

RECEIVING

zip = gv_zip.

CALL FUNCTION 'SCMS_BASE64_ENCODE_STR'

EXPORTING

input = gv_zip

IMPORTING

output = lv_encoded_b64.

EXPORT my_data = lv_encoded_b64 TO DATA BUFFER lv_buffer.

IMPORT my_data TO lv_contents FROM DATA BUFFER lv_buffer IN CHAR-TO-HEX MODE.

My problem is to send encoded base64 xstring to Ariba.

But as per my understanding base64 format is string, thats why I convert the value from string to xstring after being encoded.

Now I'm receiving error from my webservice saying there is serialization/deserialization error.

Please advice am I missing some step or is it because the base64 format provided by abap is different with what Ariba is expeceted.

Regards,

If you have a XSTRING field as a return parameter (or a component) of your webservice, it will be transformed automatically to base 64. So just use gv_zip and remove the explicit conversions.

Thanks Sandra,

This clarification is exactly what I need.

I have try to follow your suggestion error 'SOAP:1027 SRT: Serialization / Deserialization failed' still persist but web method successfully executed with document response.

At least now I know now that error was generic and its not something that always related with encoding and decoding of base64.

Thanks,
