Access the .Net Service From ABAP.

[BalaMalvatu]

Hi,

Is there any Sample code or Guide to Access the .Net Webservice From ABAP Program.

My Coding is Throwing Error.The data is Transfered into xml.

CALL TRANSFORMATION ('ZDOWNPAYMENTCREDITCARD') " Convert into Xml

SOURCE root = wa_creditcard

RESULT XML out_xml.

• Request aufbereiten

CLEAR: i_request_len, str_request_len.

i_request_len = XSTRLEN( out_xml ).

MOVE: i_request_len TO str_request_len.

CALL METHOD cl_http_client=>create_by_destination

EXPORTING

destination = 'IHOMECOMPUTOP'

IMPORTING

client = http_client

EXCEPTIONS

argument_not_found = 1

destination_not_found = 2

destination_no_authority = 3

plugin_not_active = 4

internal_error = 5

OTHERS = 6.

CALL METHOD http_client->request->set_header_field

EXPORTING

name = '/WebService.asmx/DownpaymentCreditCard'

value = 'POST'.

CALL METHOD http_client->request->set_header_field

EXPORTING

name = '~server_protocol'

value = 'HTTP/1.1'.

CALL METHOD http_client->request->set_header_field

EXPORTING

name = 'Content-Type'

value = 'text/xml; charset=utf-8'.

CALL METHOD http_client->request->set_header_field

EXPORTING

name = 'SOAPAction'

value = '"http://Testservice/DownpaymentCreditCard.asmx'.

CALL METHOD http_client->request->set_data

EXPORTING

data = out_xml

offset = 0

length = i_request_len.

CALL FUNCTION 'CRM_IC_XML_XSTRING2STRING'

EXPORTING

inxstring = out_xml

IMPORTING

outstring = r_str.

CALL METHOD http_client->send

EXPORTING

timeout = 0

EXCEPTIONS

http_communication_failure = 1

http_invalid_state = 2

http_processing_failed = 3

http_invalid_timeout = 4

OTHERS = 5.

CALL METHOD http_client->receive

EXCEPTIONS

http_communication_failure = 1

http_invalid_state = 2

http_processing_failed = 3

OTHERS = 4.

output_xml = http_client->response->get_data( ).

• Check HTTP Status

CALL METHOD http_client->response->get_status

IMPORTING

code = status_code

reason = status_reason.

Error Is

<?xml version="1.0"?><soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/

envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http

Hi Bala,

check out this presentation, here they talk about consuming Web Services from ABAP: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/a4433436-0301-0010-f2a9-9281ad57.... Have you tested the .NET Web Service from a .NET application, the error looks like the Web Service throws an error which is not properly catched, in case you have access to the .NET code I would recommend doing some tracing.
