Submit button how does it work in noninteractive forms

Question

Hi ,
I read the below part in one of the articles on interactive forms . can anyone explain how this is done ....
An interactive form can, in standalone, make a call to some web service. And as you may know, in the NetWeaver versions of SAP systems, every remote-enabled function module can be exposed as a web service!
The web service call logic is embedded in the Interactive Form you sent to your customer. When he clicks on 'Submit';, the web service is called, and your SAP backend is updated. Great!
As per my understanding a RFC FM is created and it is configured in the SFP transaction.. is it correct ?

Hi Abhilash,
how create web service in WAS you can read in "Access SAP Business Functions (ABAP) via Web Services" https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/06adbf03-0a01-0010-f386-d8e45561a3c4
Here is an example. Move code bellow to click event of a regular button (Control Type = Regular). In this example I use my function module ZHRABAM_ECHO_STRING which can be called as a web service.
[code]callWebService();
function callWebService() {
  var lXmlData=GetData();
  try{
    SOAP.wireDump = false;
    var oURL = "http://server:8005/sap/bc/soap/wsdl11?services=ZHRABAM_ECHO_STRING&sap-client=100";
    var service = SOAP.connect(oURL);
    if(typeof service != "object") {
      xfa.host.messageBox("Error calling the Web Service.");
      return;
    if (service.ZHRABAM_ECHO_STRING == "undefined") {
      xfa.host.messageBox("Error calling the Web Service.");
      return;
    var lResult = service.ZHRABAM_ECHO_STRING();
    if( lResult != null){
      xfa.host.messageBox("Result: "+lResult);
    } else {
      xfa.host.messageBox("Result is null.");
  } catch (e) {app.alert(e.message);}
function GetData() {
  var myDataNode = null;
  var xml = "";
  try {
    myDataNode = xfa.resolveNode("$data.nodes.item(0)");
    xml = myDataNode.saveXML();
  } catch (ex) {}
  return xml;
}[/code]
[code]FUNCTION ZHRABAM_ECHO_STRING.
""Local Interface:
*"  IMPORTING
*"     VALUE(IV_TEXT) TYPE  STRING
*"  EXPORTING
*"     VALUE(EV_TEXT) TYPE  STRING
ev_text = iv_text.
ENDFUNCTION.[/code]
