    <p>In my scenario, I have frameworks comprising of SAP Business Data(in json format), nodejs middle layer and a Browser front-end. I need to create a real-time application of pull the SAP business to the front-end, make edits and send the edited data back to the sap server.</p> <p>Now, to achieve this I am using <code>express</code> and <code>http</code> module. I am using express(post request) to connect to sap backend and retrieve data in json format and have embedded a http webserver, which is hosting the json data as an url used by the front-end.</p> <p>When the user, make edits in the front-end, I am able to get the response from the httpServer instance response, but the outer express post response is returning before I can delegate the httpResponse form the browser as the express post response.</p> <p>I am including a part of the code, or illustration :</p> <pre><code> app.post('/publish', auth, function (request, response) { json = JSON.stringify(request.body); //io.sockets.emit("SAP_Event", request.body); http.createServer(function(req,res){ //var f = 'index.html'; if(res.url == '/favicon.ico'){ // To handle non-existant favicon request by the http client res.writeHead(404,{'Content-Type' : 'text/plain'}); res.end('Couldn\'t locate the required resource'); return; } var headers = { 'Content-type' : 'application/json' , 'Access-Control-Allow-Origin' : '*', 'Access-Control-Allow-Headers' : 'X-Requested-With,GET,Content-Type'}; res.writeHead(200,headers); res.end(json); //*********************************** if(req.method === "POST") { var data = ""; req.on("data", function(chunk) { data += chunk; }); req.on("end", function() { jsonp = qs.parse(data); }); } //*********************************** }).listen(8080); response.send(jsonp); }); </code></pre> <p><strong>Note:</strong> json is the pulled json(sap -> frontend) jsonp is the pushed(modified) json (frontend -> frontend)</p> <p>I want response.send(jsonp) to send the modified json file, but its returning [] i.e its initial value, moreover I am getting the modified json, the next time restart the server program in sap.<br/>Please Help!!</p>

    1. COWhy are you creating http server within a route in express ?? If you want to fetch data from SAP business data you need to get that with `http.request`. But instead you are reading from a file so why do you need an http server ?

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
