Create
Update
Delete
Prerequisites
- You have to installed the SAPUI5 Application Development Tool into your Eclipse
- UI Development Toolkit for HTML5 Version SAPUI5 1.16
Steps to be followed :-
- 1. Create the Project :
create a SAPUI5 MVC project in eclips
It shows like below mentioned in the picture :
- 2. Creating the view components and fetching the Bank data :
Add following code in to the bank.view.js
- sap.ui.jsview(“bankcrud.bank”, {
/** Specifies the Controller belonging to this View.
* In the case that it is not implemented, or that “null” is returned, this View does not have a Controller.
* @memberOf bankcrud.bank
*/
getControllerName : function() {
return “bankcrud.bank”;
},
/** Is initially called once after the Controller has been instantiated. It is the place where the UI is constructed.
* Since the Controller is given to this method, its event handlers can be attached right away.
* @memberOf bankcrud.bank
*/
createContent : function(oController) {
var layout = new sap.ui.commons.layout.MatrixLayout({
id : ‘matrix4’,
layoutFixed : false,
});
var appHeader = new sap.ui.commons.ApplicationHeader(‘appHeader’, {
logoText : “Bank Application”,
displayLogoff : false,
displayWelcome : true,
userName : “Welcome”
});
layout.createRow(appHeader);
var rPannel = new sap.ui.commons.Panel(‘rPannel’, {
text : “BankCollection List”,
});
var oTable = new sap.ui.table.DataTable({
id : “bankTableID”,
title: “Bank CRUD Application”,
width : “100%”,
visibleRowCount: 10,
selectionMode : sap.ui.table.SelectionMode.Single,
//setEditable : false,
rowSelectionChange : function(oEvent) {},
toolbar: new sap.ui.commons.Toolbar({
items: [
new sap.ui.commons.Button({
text: “Create”,
press: function() {
oController.Create();
}
}),
new sap.ui.commons.Button({
text: “Update”,
press: function() {
oController.Update();
}
}),
new sap.ui.commons.Button({
text: “Delete”,
press: function() {
oController.Delete();
}
}),
]
}
});
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : “Bank ID”
}),
template : new sap.ui.commons.TextField().bindProperty(“value”,
“bankID”),
sortProperty : “bankID”
}));
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : “Bank Country”
}),
template : new sap.ui.commons.TextField().bindProperty(“value”,
“bankCountry”),
sortProperty : “bankCountry”
}));
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : “Bank Name”
}),
template : new sap.ui.commons.TextField().bindProperty(“value”,
“bankName”),
sortProperty : “bankName”
}));
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : “Region”
}),
template : new sap.ui.commons.TextField().bindProperty(“value”,
“region”),
sortProperty : “region”
}));
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : “Street”
}),
template : new sap.ui.commons.TextField().bindProperty(“value”,
“street”),
sortProperty : “street”
}));
oTable.addColumn(new sap.ui.table.Column({
label : new sap.ui.commons.Label({
text : “City”
}),
template : new sap.ui.commons.TextField().bindProperty(“value”,
“city”),
sortProperty : “city”
}));
// Add table to the Panel
rPannel.addContent(oTable);
// Add panel to the Layout
layout.createRow(rPannel);
// Display Layout
this.addContent(layout);
}
});
Then bind the bank table in controller file. Add the following code in to the “onInit“ function
onInit: function() {
//Initialize the Model
var oModel = new sap.ui.model.odata.ODataModel( “http://domain_name/sap/opu/odata/sap/Z_TM_BANK_SRV“,false, “Username”, “Password”);
//Set the Model to the Table
var oTable = sap.ui.getCore().byId(“bankTableID”);
oTable.setModel(oModel);
// Filter the DATA
var FilterOperator = sap.ui.model.FilterOperator;
var filter = new sap.ui.model.Filter(“bankCountry”,FilterOperator.EQ, “AR”);
//Bind the Data to the Table
oTable.bindRows(“/BankCollection”, null, null,[ filter ]);
},
Output :
After binding the table :
Create Operation :
- 1. Add the button in view file (already created-in view file)
- 2. Create the function for create operation in controller file
Add the following code mentioned below :
Create: function() {
// Create a dialog to get the information of the bank to be created
var oDialog = new sap.ui.commons.Dialog(“Dialog”, {
modal: true,
closed: function(oControlEvent){
sap.ui.getCore().getElementById(‘Dialog’).destroy();
}
});
oDialog.setTitle(“New Bank Collection”);
// Create a layout to place the controls in the dialog
var oLayout = new sap.ui.commons.layout.MatrixLayout({
columns: 2,
width: “100%”
});
// Create text field for the bankCountry
var oTF = new sap.ui.commons.TextField(“tbankCountry”, {
tooltip: ‘Bank Country’,
editable: true,
width: ‘200px’,
required: true
});
var oLabel = new sap.ui.commons.Label(“lbankCountry”, {
text: ‘Bank Country’,
labelFor: oTF
});
// Create the first row
oLayout.createRow(oLabel, oTF);
// Create text field for the bankID
oTF = new sap.ui.commons.TextField(“tbankID”, {
tooltip: ‘Bank ID’,
editable: true,
required: true,
width: ‘200px’
});
oLabel = new sap.ui.commons.Label(“lbankID”, {

In this way we can create the desktop application in sapui5 with MVC structure and for the bacnkend data we have to consume the Nerweaver Gateway Service.In this application Odta Model is used.
Which service do you use?
Hi,
In this application I used Odata Model.
hi:shruti
Thank you for sharing, according to your article, the effect is a success.
But there is a problem, updating the data, the table of contents can not be refreshed. I must go to click browser refresh button to get the updated data
Is there any way you can update the complete data, and can refresh the contents of the table in time?
best regard!
document.location.reload(true);
$("<div>Returned data " + window.JSON.stringify(data) + "</div>").appendTo($("#MessageDiv"));
},
Hi Huang, Its possible.
Make sure you are using the above code inside function (data, request)
Best Regards

hi:Seyed
Thank you for your reply, the problem has been resolved
best regard
Well explanation shruti.
Thanks,
Syam
Thanks Syam..
Great article, really good level of detail, and helped me with my second steps in Eclipse development. I'm using JSON rather than oData, but the design and layout bits in Eclipse are the same. Thanks for your contribution, and it's a great example for others on SDN!
Thanks for the feedback Patrick
Hi Shruti, you don't happen to have the whole project saved, do you?
I'm still running into a few problems, if you do, would you mind sharing it?
Thanks and Regards
Alex
Hi Alexandre,
In the blog I mentioned whole project.It's working properly.Where you struck explain me in detail.
Regards
Shruti
Forget everything else, got pretty much everything to work, but the update part.
I'm getting :
Uncaught ReferenceError: selectedRow is not defined
any tips on that?
Thanks and Regards
Alex
HI Alexandre,
sorry for the late reply.
define the "selectedRow" as variable like below mentioned.
Regards
Shruti
Shruti - great write up and information. I have been trying the methods described, but if I scroll down on my table, select a row that was not on the original view and click the update button, I get an error that selectedRow does not exist.
It works great if I don't scroll down in the table. I am using Chrome (32) and I have also tested in Firefox (27). Is this a known issue or am I doing something strange?
Thank you.
I solved the update after scrolling problem. I removed the oTable.getRows()[i] statement and used getContextByIndex(i) instead.
//var selectedRow = oTable.getRows()[i];
var selectedRow = oTable.getContextByIndex(i);
var selectedID = selectedRow.getProperty('ID');
Could you tell me which type of file you store in Z_TM_BANK_SRV???
Hi Shruti,
thanks for the example. I get an error message in line "rowSelectionChange : function(oEvent) {}," in the view file. Eclipse tells me that a semicolon is missing. Do you have an idea for that?
Thanks.
Regards, Andreas
Hi Andreas,
What i mentioned it is correct only,there is no need of semicolon there. Could you please provide me the screenshot of that error ,to resolve the issue.
Regards
Shruti
Hi Shruti,
Thanks for your reply. Down below the coding of my view (I havent created the controller file so far). Also the image is attached that shows the first error message in the file followed by a couple of error messages.

Hi Shruti,
Thanks for your support. Now I don't have any error message anymore. I will use my own oData model and adjust the coding. But may I ask you one more question? What kind of file is Z_TM_BANK_SRV?
Thanks.
Regards, Andreas
Hi Andreas,
Z_TM_BANK_SRV is the netweaver gateway odata service.

Shruti
Hi Shruti,
Thanks.
Regards, Andreas
Hi Shruti,
Really very great work and useful info for beginners.
Thank you so much.
It would be even better if you shared your OData service details, like Entity Types & the DDIC/RFC FM you used.
Thanks again.
I am getting an error:
POST http://user:server/sap/opu/odata/sap/ZUI5_KSS_MAC_SRV/Employees 403 (Forbidden)
Hi Shruti,
Your article is really very good & easy to understand.
But i am getting error if i am running my app on firefox, error is "NetworkError: 403 Forbidden - ......".
Can you please tell what could be the reason..!!!
Hi Shruti,
Thanks for this article. Very informative. I would like to ask just one question. The application above uses Z_TM_BANK_SRV gateway service. Just wondering if we have to create our own BANK_SRV on our system or have you tried using SAP's demo of this gateway service in SAP Gateway Demo System.
Hi Melanie Saldua,
Thank you... I used SAP demo bank service only..
Hi shruti,
thank you for this great tutorial. Really well done.
The create and update functionnalities works fine for me but delete doesn't work.
Here is the error:
Do you have an idea why?
I'm using the SAP Netweaver Gateway Demo System.
Best,
Matt
PS: I've checked it with Postman and I have the following error message:
Method 'BANKCOLLECTION_DELETE_ENTITY' not implemented in data provider class
It seems we cann't do any delete action
Do you solved your problem? I ask, because I have the same issue.
Hello Shruti:
Could you please tell me the function module of demo bank ?
I want to build the odata service,but I don't find the function module.
Thank you very much.
lexian.
Hi,
Below of bank function modules
BAPI_BANK_GETLIST
BAPI_BANK_GETDETAIL
BAPI_BANK_CREATE
BAPI_BANK_CHANGE
BAPI_BANK_DELETE
Thanks,
Syam
Hi Syam,
Thank you for providing me with these modules.
I want to know which modules this blog use?
thank you .
Hi,
I am using the delete functionality in my application as stated above.
I want to display 'sap-message' in front end which is returned from SAP in HTTP Response header like this:
Code for Deletion:
OData.request({
requestUri: 'some url',
method: "DELETE",
headers: {
"X-Requested-With": "XMLHttpRequest",
"Content-Type": "application/atom+xml",
"DataServiceVersion": "2.0",
"X-CSRF-Token":csrfToken
}
},
function (data, response){
console.log(response);
}
);
The console.log returns:
It doesnt returns 'sap-message' field at all.
Can any one please tell what could be the reason?
Regards,
Meghna
Hi Meghna,
I am not sure whether you can catch the expected error via OData.request. I will look into it. Meanwhile, Please go through think link.
Deleting Entries
Entries are deleted by executing an HTTP DELETE request against a URI that points at the Entry. If the operation executed successfully servers should return 200 (OK) with no response body.
If the Entry has dependent Entries such as Entries Linked to it, it is up to the server whether deletion should be cascaded, the operation should fail because of the presence of dependent Entries, or if Links are left dangling after the Entry is deleted. This largely depends on the server, storage model and the actual application the OData service is a part of.
In the case of Media Link Entries, deleting the Media Link Entry also deletes the Media Resource.

Hello everyone:
I have created the view controller and run ok.
But now I have a problem about Odata Service in SEGW,Syam told me these function:
1 BAPI_BANK_GETLIST
2 BAPI_BANK_GETDETAIL
3 BAPI_BANK_CREATE
4 BAPI_BANK_CHANGE
5 BAPI_BANK_DELETE
I know we have to create a Z_TM_BANK_SRV gateway service in SEGW,
but I am confused is which function will be used or above all?
It would be better if someone shared your OData service details, like Entity Types & the DDIC/RFC FM you used.
thank you very much,
Best wishes for you.
lexian.
Most of the functionality you build with custom ajax requests (OData.request() functions) can be rewritten in a much easier way with the built-in functions such as read(), create(), update(), and remove() on the ODataModel (SAPUI5 SDK - Demo Kit)
Hello Shruti !!
Your tutorial must be very useful
But I am facing problem in the beginning after creating bank controller & bank view, i am not getting any error and not getting any result as well.
kindly tell me where am i wrong?
Service i am using is: https://sapes1.sapdevcenter.com/sap/opu/odata/sap/Z_BANK
Hi All,
I am trying for POST operation however I am getting error : Uncaught ReferenceError: OData is not defined
My Code is :
OData.request({
requestUri : "MYURL",
headers : {
Hedear Info
},
method : "POST",
data : connectiondata
}, onSuccess, onError);
Any suggestions on this ? Do I need to declare it somewhere first before use ? As per my understanding OData is default object. Correct me if I am wrong.
Thanks ,
Mahesh.
Hi ,
I added data.js to my index.htrnl file and its working now 🙂
Thanks ,
Mahesh.
Hi Mahesh,
I'm also getting the same error Uncaught ReferenceError: OData is not defined. how can I add the data.js file and what information that file should keep?. Please assist me.
Thanks,
Duraivenkatesh.R
Hello Venkatesh,
You need to download datajs-1.0.1.min.js file and put it inside your project folder( I kept it at this location for my project :logindemo/resources/utils/) . Then add that path inside your index.html as follows.
<script type="text/javascript" src="logindemo/resources/utils/datajs-1.0.1.min.js"></script>
Thanks ,
Mahesh.

proxy/http/ranak.com/emplist-web/emplist.svc
Is this correct? Please check it by opening in a separate tab.
Seyed Ismail.
Hi ,
This url is correct . I have displayed the records which is in this url . I cannot able to create new record in sap ui5 .
Thanks & Regards
Deepika
Hi,
Try with Normal URL inside OData.request , both GET as well as POST request.
http://ranak.com/emplist-web/emplist.svc
Normally, we use proxy when we create ODatamodel object. Also , check if your createentity method is getting invoked or not on the gateway side.
Thanks,
Mahesh.
Hi Sir ,
If i give the url which u have suggested , i am getting the following error .
Thanks & Regards
Deepika
Hello Deepika,
This is because you are trying to access the remote host service from your localhost.
In this case , you need to disable your web-security of browser.
http://stackoverflow.com/questions/24290149/creating-google-chrome-shortcut-with-disable-web-security
This is not needed when you deploy your application to gateway server.
Once you disable the web security , you wont get this error.
One more thing is , My name is not Sir , its Mahesh
Thanks,
Mahesh.
One simple method to get URL :
function getODataServiceURL() {
var sServiceURL = "Relative Path of your service";
if (window.location.host === 'localhost') {
return "http://hostname:port" + sServiceURL;
} else {
return sServiceURL;
}
}
Thanks ,
Mahesh.

Hi Shruthi,
Thanks for your sharing knowledge on CRUD operations with sample application.
It helps a lot like us to learn how to connect ecliplse to Odata.
At first I missed headers in the request tag and trying.
After seeing yours blog I got to know that I missed something.
Now, I have successfully connected and retrieving the data.

Hi Shruthi,
Thank you for the blog. My requirement is to perform the create functionality. When I submit the data I get the below error.
It is an immediate requirement. Hope you can provide some suggestions regarding it.
Thanks,

Hi All,
I have just started learning. I don't understand one thing. I have seen code for CRUD operations using Odata in this example follows different syntax and complex. I have seen Other different way which used by my colleague.
Could you please anybody tell the difference if any ?
Hey,
I have created my service and got the generated URL but while passing it in the controller I am not getting the table contents in the UI app. It would be really helpful if you could help me with it.
Thanks in advance
worst way to display the code in the blog !!
