Hi,

I have a requirement to send the xml file from ecc to a 3rd party url through HTTPS. How can we achieve this using ABAP.

Client doesn't have XI enviroment. The client has provided the 3rd party url where the file needs to be uploaded.

Please help ! <removed by moderator>

Thanks in advance.

Regards,

Chitra.K

Hi Chitra,

I had similar requirement and here is what I did: -


REPORT  Z_HTTP_POST_TEST_AMEY.

Also, in below link, you can ignore XI specific part and observe how its sending XML to external URL:-

(I know it describes call to SAP XI server's URL, but it can be used to call any URL)

http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/ae388f45-0901-0010-0f99-a76d785e3ccc

In addition to all above, following configs to be present at ABAP application server: -

1. The hostname used to URL should be present in SAP ABAP application server's 'hosts' file.

2. Security certificate (if available) for URL to be called must be installed in SAP ABAP application server.

Let me know if you achieve any progress with it...

When tried to use this solution to upload a file to Sharepoint, the following statement did not work:

CALL METHOD L_HTTP_CLIENT->REQUEST->SET_HEADER_FIELD

    EXPORTING NAME  = '~request_method'

               VALUE = 'POST' .

I had to use:

CALL METHOD L_HTTP_CLIENT->REQUEST->SET_HEADER_FIELD

    EXPORTING NAME  = '~request_method'

               VALUE = 'PUT' .

Also be aware that Sharepoint requires the full domain qualified name e.g. "domain\username" and not just "username".

My test program ended up as:

*&---------------------------------------------------------------------*

*& Report  ZTEMP_HTTP_XML

*&

*& This program uploads a file to a Sharepoint folder.
