How do I set SOAP Headers when calling Client Proxies?

[Former Member]

Hi all,

I'm trying to call a SalesForce Web Service from ABAP.

I've generated an Enterprise WSDL in salesforce and created my client proxy in SAP.

Salesforce requires you to login which passes a sessionId back and you then use the sessionId in subsequent calls (e.g. to create an Asset).

The login is working fine.

However I can't work out how to set the session id.

The Payload needs to look similar to the sample payload I have included below

What I'm ideally after is some sample abap to populate the soapenv:Header with the Session Id.

Or if there is a way of configuring this in the proxy or soamanager.

Regards,

John

Sample Payload

<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"

xmlns:urn="urn:enterprise.soap.sforce.com"

</urn:SessionHeader>

</soapenv:Header>

<soapenv:Body>

Hi,

You need to use WS_HEADER to access parameters.

you can see source code exmple here:

SAP help documentation here: http://help.sap.com/saphelp_nwpi71/helpdata/en/51/d5cd16235e4643ae8ec92395c4ad97/frameset.htm

Hi John

I have the same problem like you. Iu2019m able to do the login.

Then I use the WS_HEADER as explained in .

TRY.

• Additional Header:

CONCATENATE '<soapenv:Header>'

'<urn:SessionHeader>'

'<urn:sessionId>' login_output-result-session_id '</urn:sessionId>'

'</urn:SessionHeader>'

'</soapenv:Header>'

INTO l_string.

• convert to xstring

l_xstring = cl_proxy_service=>cstring2xstring( l_string ).

ws_header ?= obj_add->get_protocol('IF_WSPROTOCOL_WS_HEADER').

IF NOT l_string IS INITIAL.

• create iXML DOM document from XML xstring

CALL FUNCTION 'SDIXML_XML_TO_DOM'

EXPORTING

xml = l_xstring

IMPORTING

document = xml_document

EXCEPTIONS

invalid_input = 1

OTHERS = 2.

IF sy-subrc = 0 AND NOT xml_document IS INITIAL.

xml_root = xml_document->get_root_element( ).

xml_element ?= xml_root->get_first_child( ).

• add header element by element to SOAP header

WHILE NOT xml_element IS INITIAL.

name = xml_element->get_name( ).

namespace = xml_element->get_namespace_uri( ).

namespace = 'urn:partner.soap.sforce.com'.

IF NOT xml_element IS INITIAL.

ENDIF.

• get WS_HEADER protocol

ws_header->set_request_header(

name = name

namespace = namespace

dom = xml_element ).

xml_element ?= xml_element->get_next( ).

ENDWHILE.

ENDIF.

ENDIF.

CATCH cx_ai_system_fault .

ENDTRY.

When Iu2019m calling the query-method, I get a Parser Error (CX_SXML_PARSE_ERROR). I think itu2019s from the Header.

Could you show me how you have done this part of coding?

Thanks,

Hi Daniel,

You also need to define prefix "urn" in header, edit header and then test . If still facing problem then please see log for error detail.

Example:

'<urn:SessionHeader xmlns:urn="yournamespace"> '
