In my previouse blog Use nodejs soap to block supplier invoice by call soap api in s/4 hana cloud,we can payment block supplier invoice with local application. Today I want to blog down developing and deploying  a rest api application on BTP Cloud foundry  to realize the same function.On BTP,we need to use destination  to call soap api in  s/4 hana  cloud . To to this , we need to replace the default httpClient used in soap client library .

For developing and deploying MTA application , please refer to the blog.  The folowing is the how is the MTA application look like .

We need to replace the  httpClient used SOAP client with sap-cf-axios to utilize destination . The following is the js code .

const express = require('express');
const app = express();
const bodyParser = require('body-parser');
// const cds = require('@sap/cds');
const core = require('@sap-cloud-sdk/core')
const short = require('short-uuid');
const uuid = require('uuid');
const SapCfAxios = require('sap-cf-axios').default;

const { retrieveJwt } = require('@sap-cloud-sdk/core');
const { desc } = require('@sap-cloud-sdk/core');




url = '/sap/bc/srt/scs_ext/sap/journalentrybulkchangerequest_';

const xssec = require('@sap/xssec');
const passport = require('passport');
const soap = require('soap');
const xsenv = require('@sap/xsenv');
xsenv.loadEnv();
const services = xsenv.getServices({
    uaa: { tag: 'xsuaa' }
});
passport.use('JWT', new xssec.JWTStrategy(services.uaa));
app.use(passport.initialize());
app.use(passport.authenticate('JWT', {
    session: false
}));


app.use(bodyParser.json());

var invoiceblock = function(req,res){

    if (req.authInfo.checkScope('$XSAPPNAME.User')) {
  
  
        const destinationName = "O5P";
        const axios = SapCfAxios(destinationName);
          
        var httpClient1 = {
            request: function (url, data, callback, exheaders, exoptions) {
                axios({
                    method: 'POST',
                    url: url,
                    data: data,
                    headers: exheaders
                }).then((result) => {
                    callback(null, result, result.data);
                }).catch((e) => {
                    callback(e);
                });
            }
        }

        var options = {
            httpClient:httpClient1,
            forceSoap12Headers: true
          };

    soap.createClient('./external/JOURNALENTRYBULKCHANGEREQUEST_.wsdl',options,function(err,client){
        if(err){
            console.log('soap client creation failed');
            console.log(err);
            res.status(500).send( err.toString())}
            else{

    client.setEndpoint(url);
   
    var sid =short.generate();
    var id = uuid.v1();
    var date1 =new Date().toISOString();
   
    var args = {'MessageHeader':{'ID':sid,'UUID':id,'CreationDateTime':date1},'JournalEntryHeader':{'MessageHeader':{'ID':sid,'CreationDateTime':date1},'HeaderKey':{'AccountingDocument':'5100000050','CompanyCode':'1310','FiscalYear':'2022'},'DocumentHeaderTextChange':{'DocumentHeaderText':'hello1','FieldValueChangeIsRequested':true}},'JournalEntryDebtorCreditorItem':{'MessageHeader':{'ID':sid,'CreationDateTime':date1},'ItemKey':{'AccountingDocument':'5100000050','CompanyCode':'1310','FiscalYear':'2022','AccountingDocumentItemID':'1'},'PaymentBlockingReasonCodeChange':{'PaymentBlockingReasonCode':'A','FieldValueChangeIsRequested':true}}};

    client.addSoapHeader({MessageID:id},'http://www.w3.org/2005/08/addressing','wsa','http://www.w3.org/2005/08/addressing');
    
    client.JournalEntryBulkChangeRequest_In(args,function(err,result){
    if(err){
        console.log('soap call failed');
        console.log(err);
        res.status(500).send(err.toString());}else{res.status(200).send('Journal Entry sent successfully!');}
   });}
  
    });
  
  } else {
        res.status(403).send('Forbidden');}}
    
app.get('/srv/grir',invoiceblock);

app.get('/srv', function (req, res) {
    if (req.authInfo.checkScope('$XSAPPNAME.User')) {
        res.status(200).send('mtasoap2');
    } else {
        res.status(403).send('Forbidden');
    }
});

const port = process.env.PORT || 5001;
app.listen(port, function () {
    console.info('Listening on http://localhost:' + port);
});

The following is the code for package.json

{
  "name": "mtasoap2-srv",
  "engines": {
    "node": "14.x"
  },
  "dependencies": {
    "@sap-cloud-sdk/core": "1.54.2",
    "@sap/cloud-sdk-vdm-sales-order-service": "2.0.0",
    "@sap/xsenv": "3.2.2",
    "@sap/xssec": "3.2.13",
    "body-parser": "1.20.0",

    "soap": "^0.43.0",
    "uuid": "^8.3.2"
  },
  "scripts": {
    "start": "node server.js"
