Calling webservice in Adobe interactive form

Question

Hi,
I have a webservice created for a function module which in turn calls the BAPI_PR_CREATE (purchase requisition creation) BAPI. I am trying to call this webservice from an Adobe interactive form I've created. Basically the user will enter all necessary data inside the form and when he presses a button the webservice should be called and the purchase requisition should be created.
My question is what type of "Control type" should I use for the button "Regular", "Execute" or "Submit" and how should the javascript code look like?
I have tried a lot of solutions that I've found on the internet but nothing worked.
The ADS service is not yet installed, I know that this is a big issue but could this affect the functionality or could this be the cause why nothing seem to work?
Thank you and Best Regards,
Mihai

Hi Florian,
thank you for the given information.
Unfortunatelly I was waiting for a long time from the BASIS team to install the ADS. Yesterday they've told me it's finally done.
Consequently I started to retest the solutions I've found but with no result so far.
I've tried to make the button an "Execute" control type and added the Connection inside the Execute tab.
I've also tried with the following javascript inside the xml file (inside the click event of the button) and all of the button control types:
var tempsoapAddress = xfa.connectionSet.DataConnection.getElement("soapAddress").value;
var tempwsdladdress = xfa.connectionSet.DataConnection.getElement("wsdlAddress").value;
var ServerPath = body.systemConfig.system.rawValue;
var client = <Get Client from a data attribute>
var Soap_PreServerPort =  "http://";
var Soap_PostServerPort =  "/sap/bc/soap/rfc?sap-client=";
var SoapAddress = Soap_PreServerPort + ServerPath + Soap_PostServerPort + client ;
var Wsdl_PreServerPort =  "http://";
var Wsdl_PostServerPort1 =  "/sap/bc/soap/wsdl11?services=ZBAPI_PO_CREATE2&amp;sap-client=";
var wsdlAddress =  Wsdl_PreServerPort + ServerPath + Wsdl_PostServerPort1 + client ;
xfa.connectionSet.DataConnection.getElement("soapAddress").value = SoapAddress;
xfa.connectionSet.DataConnection.getElement("wsdlAddress").value = wsdlAddress;
xfa.connectionSet.DataConnection.execute(0);
xfa.connectionSet.DataConnection.getElement("soapAddress").value = tempsoapAddress;
xfa.connectionSet.DataConnection.getElement("wsdlAddress").value = tempwsdladdress;
xfa.connectionSet.DataConnection = null;
I've also found that maybe I should have attached the following roles and authorization objects to my user:
Authorization objects: S_USER_PRO, S_SERVICE and S_ICF_ADMIN, S_SRT_ADM
Roles:
a) SAP_BC_WEBSERVICE_ADMIN
b) SAP_BC_WEBSERVICE_ADMIN_BIZ
c) SAP_BC_WEBSERVICE_ADMIN_TEC
d) SAP_BC_WEBSERVICE_CONSUMER
e) SAP_BC_WEBSERVICE_DEBUGGER
f) SAP_BC_WEBSERVICE_OBSERVER
g) SAP_BC_WEBSERVICE_SERVICE_USER
Do you have ideea what could be the issue? Can you give me another solution?
Thank you and Best Regards,
Mihai
