After adding the destination, to reflect it in Web IDE you have to refresh Web IDE.
Given below is one of my gateway configuration (trial available through SCN). It might help you.

SEGW : Copy Project vs Redefine(OData Service)

Dear Friends,
This is regarding the differences between various modeling approaches in SEGW
1. An Existing Project ( and Technical Service , say, Parent 1.0 ) is live
2. A new Project ( and Technical Service , say, Child 1.0) is to be implemented.
What is the real difference between
(A) ... copying the existing project "Parent" to "Child" and publishing the Technical service as "Child 1.0"
(B) ...copying the existing project "Parent" to "Child" and publishing the Technical service as "Parent 2.0"
(C) ...Redefining the "Parent 1.0" in a new project "Child" and "Overwrite Base/Extend the Service" ...which publishes the Technical Service as "Parent 1.0"
(D) ...Redefining the "Parent 1.0" in a new project "Child" ..without "Overwrite Base/Extend the Service" .. and publish the Technical Service as "Child 1.0"
In other words, what really is the idea of "Redefine >OData Service (GW)" ...( with / without "Overwrite Base/Extend the Service" )
Many thanks for your patience
Suresh

Hi Suresh,
by copying the project you create a complete independent new project, which does not have any relation to the original project. The runtime objects (model provider classes and data provider classes) are independent from those of the first project.
By redefining the project you can select which entities and which associations you want to use in your child project. Those redefined objects can't be changed in the child project, you only can redefine names and labels. On the other hand if you change any of the redefined object attributes in the parent project the changes will also be available in the child project.
And the data provider class of the child project inherits from the one of the parent project.
So you have a real parent-child relationship.
Redefining with option "Extend" means to add objects of the parent project, which haven't been redefined before.
Redefining with option "Overwrite" means to redo the redefinition. All redefinitions done earlier will be overwritten. Objects which had been redefined before, but are not selected in the new redefinition will be deleted from the child project.
Hope that makes it a little bit clearer.

Juergen

Error while running an Odata service in Advanced Rest Client

Hi Experts,
We have created one simple OData model (using Integration gateway) with datasource as SOAP web service. We are able to test the SOAP Web service in STORM tool and getting desired response. But when we run the converted OData URL in Advanced REST Client we are getting the following exceptions/errors.
Could not send message
Also, while looking at SMP3 server log, we came across below error logs:

Error while consuming Odata service from Gateway client i.e /iwfnd/gw_client

Hello Experts.
I am facing below an error while consuming the Odata service from GW client... The error is "No service found for the namespace /IWFND/,name ZTEST_STOREROOM_SRV,version 001". Even i have tried to deep dive in /IWFND/Error_log but no use..
Actually what I was doing :- My aim is to connect multiple back end systems in the same server with the help of Aliasing concept.. I have created multiple aliases and added in the /IWFND/MAINT_Service transaction.. but i am not getting how to consume the service..
I have followed the solution upto some extent in the link => Multiple Origin Composition - SAP NetWeaver Gateway Foundation (SAP_GWFND) - SAP Library
Can you please let me know how to resolve this.. Also please let me know, the syntax for the URI...
Your help is highly appreciated..
Please find the screenshot attached.
Thanks,

i tried with IE still got the same problem.
And installed all the required software in eclipse
While installing GWPA plugin i got the following error.
let me know if any one have idea.
Thanks in advance.

Sorry mate, but YOU have to know what you want here.
I gave you an easy to follow set of steps.
As you don't seam to mind the outcome, just might just use them...

We had this discussion before...

Yes, you do have the SAPR3 user.
But you don't seem to like to read documentation or learn about how the tools work or anything like that.
Therefore I gave you s simple way to reach your goal.
Of course it's possible to reuse the user.
But then you would have to deal with already existing tables, already existing data etc.
You don't seem to be able to do that. So, the easy steps might be better suited for your needs.

Anyone been able to get the sap.ca.ui.FileUpload control working with a Gateway OData service?

Hi,
I have been trying to get the sap.ca.ui.FileUpload control working with an OData Gateway service, specifically /IWPGW/TASKPROCESSING which is the service used by both Fiori Approve Requests and the Unified Inbox.
I have looked at the sample application in the Explored at SAPUI5 Explored
I have managed to replicate that and get it to work, but as soon as I switch it from a JSONModel to an ODataModel I get javascript errors from within the setModel method of the control. I have redefined that method and corrected the errors, which enables me to get a bit further, but then I hit more errors, and other strange behaviour.
Either I am doing something completely wrong, or to me it appears as if this control is still extremely buggy and maybe either not designed to work with an ODataModel, or just hasn't been tested using an ODataModel. I'm hoping it is my mistake.
So has anybody out there successfully managed to use this control connecting it to a Gateway OData service? If so please share your experience.
Thanks,
Brad

Hi Pauline,
Same issue I had, I switched to using a sap.m.list and handling the press as follows:
attachmentsList.bindItems(workItemPath + "/Attachments", new sap.m.StandardListItem({
                           type: sap.m.ListType.Active,
                           title: "{FileName}",
                           description: "{CreatedByName}",
                           icon: "sap-icon://doc-attachment",
//                         counter: "{FileSize}",
                      info: {path : "CreatedAt", formatter: dateTimeFormatter},
                      tap: function(oEvent){
                            var oContext = oEvent.getSource().getBindingContext();
                            var media_src = oContext.getProperty().__metadata.media_src;
                            sap.m.URLHelper.redirect(media_src, true);
                    }), new sap.ui.model.Sorter("CreatedAt", true));
So sap.m.URLHelper.redirect(media_src, true); is what loads the attachment.
See the full function handler:
function(oEvent){
function(oEvent){
              var oContext = oEvent.getSource().getBindingContext();
              var media_src = oContext.getProperty().__metadata.media_src;
        sap.m.URLHelper.redirect(media_src, true);
This should be enough if you only want to list and display the attachments, then you don't really need the FileUploader control as that is more advanced and handles upload, display, change and deletion of files.
I only needed to upload and display files, so I used a list to display it and created a separate upload button using the sap.ui.unified.FileUploader control.
Hope that helps.
Cheers,
Brad

Consume OData service in SUP 2.1.3

Hello,
How to consume of OData service in SUP 2.1.3 for creating MBO for HWC?
Our OData service is having mandatory filters which needs to be passed.
http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/Entity_Set_Name/?$filter=Filter1 eq 'value1'and Filter2 eq 'value2'
So, while creating XSD from XML should we need to use the above URL or http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/?$format=xml
If we are using http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/?$format=xml and convert it in XSD then we are not able to see FEED in the MBO creation.
Also, if we are using http://xxx:8000/sap/opu/odata/sap/Z_TEST_V2_SRV/Entity_Set_Name/?$filter=Filter1 eq 'value1'and Filter2 eq 'value2' and convert it into XSD then we are able to see the FEED in MBO creation but while choosing the fields it is throwing us java.lang.nullpointer exception.
Can anyone explain us the solution for the problem?
Regards,
Rahul

Is there a particular reason why SUP 2.1.3 is used and not the latest 2.3.4? It is recommended to move to the most recent version if possible/new project.
For HWC consuming OData service, you can connect directly from your JavaScript without using MBOs. Please take a look at this link:
Develop OData-based Hybrid Apps

Binding to Odata Service with Input Parameters from HANA

Hello,
I'm developing a UI5 application that consumes a SAP HANA OData service to search a database (using fuzzy search). This service receives an Input Parameter, used to query the database.
So every time the user searches for something I build a new binding path and refresh the model to show the search results in the sap.m.List.
The Model:
var hanaModel = new sap.ui.model.odata.ODataModel("…/services/seed.xsodata");
this.setModel(hanaModel);
The search event handler from sap.m.SearchField:
var listBinding = this.getView().byId("list").getBinding("items");
listBinding.sPath = "/FoodstuffByNameValuesParameters(P_NAME='" + searchString + "')/Results";
this.getView().getModel().refresh();
My question is if this is the correct approach to create the model and bind the list when we have a service with an Input Parameter, or if there is a better way to do it.
(This approach is actually working).
Regards,
Paulo

i would do
var filter = [];
var selectFilter = new sap.ui.model.Filter("name", sap.ui.model.FilterOperator.Contains, sVal);
filter.push(selectFilter);
listBinding .filter(filter);

SUP 2.1.3 MBO creation using ODATA service

Hi All,
I am using SUP 2.1.3 and trying to consume OData service created using SEGW transaction on gateway. following an older document i moved ahead by creating XSD files from the XML file.
But,after uploading the XSD file , i chose the root element as 'feed' .
After this , one XSLT file is generated automatically.
But , when I click the XSLT file to edit , it shows error saying 'java.lang.NullPointerException' .
I have to follow the methodology of creating MBO's using OData service and then deploying it on server.
Please help me to move ahead with ODATA service in SUP 2.1.3 version.
Appreciate your quick help and assistance on this.
Regards
Rahul

Hi
If i ignore the Null exception error and move ahead with the XSLT format and preview the data source i receive the below error:

Query options for OData service

Hi,
I am able to create an OData service and using SDK, I am able to read the data from the connected database. Now I have to fetch data based on queries. I mean from the database table I have to fetch subset of data based on conditions. I have checked the documnetations

How to use Alias name in OData service in SAP HANA

Hi,
     I need to change one column name with alias of another name in odata service definition or odata url running in rest client. I am trying to give alias name with as key in the service definition like sql query.
ex:
There is one table with column name of PRODUCT_ID. I exporting that table via odata service to SAP UI. In the UI i dont want the product id column as PRODUCT_ID. It should be ike "Prodcut". Like we are using in SQL example
select "PRODUCT_ID" as "Product" from "producttab";
But i can't use as key for alias name. So i am getting syntax error.
I have tried in rest client also ie executing odata file in rest based service. But i got error only.
If anyone knows about this alias name in odata service, Please help me to resolve this issue..

Hi Thomas
     Thanks for your reply.
     Actually in odata service definition i am using attribute and calculation views only. But in some case from the model view itself i need to use some alias names to the UI through odata service.
     For example in attribute view i have some columns with name col1,col2... I am getting those columns in UI using odata service, for particular col2 column i need to change column name as product. And i am using the same view as source of another odata service in that service i need to change that column name as productname.
     In that case i need alias name usage. So that only i am searching alias keyword in odata service.
     Is there any possibility to use alias names in odata service.

Odata Service For Employee Information

Hi Everyone,
I want to call the odata service related to employee profile. But unable to find that service in my sap system.
Can anybody tell me the name of the odata service which need to call from the gateway or from where I will get the name of the odata service related to employee information?
Regards,
Soumya

Hi Soumya,
getting bad request means your URI is not correct. try with
http://<hostname>:<port>/sap/opu/sdata/iwcnt/employee/EmployeeCollection
let me know if you get any specific error with above query.
how can I connect to the HR system with GW? Is that can be done by using GW?
it depends if you will be getting employee details from SAP HR system which is separate from SAP NW GW or part of it. ie. based on your deployment scenarios(http://help.sap.com/saphelp_nw74/helpdata/en/3e/b1ea508f88bb7ee10000000a445394/content.htm ) and accordingly confuguration should be in place

Using WCF Odata service as SSRS data source

Hi,
We are evaluating Odata service as data source for SSRS, Idea is to use these reports in sharepoint 2010. I am not sure how to do it.
Now, I am getting a basic doubt that whether Odata can be used as SSRS data source. Please clarify my doubt. If this is possible please help me with some samples.
Thanks in advance.
Santosh

Hi Santosh,
Thanks for your post.
I am not familiar with WCF Odata service, so I would suggest you to refer to the article
Data Sources Supported by Reporting Services (SSRS),
to verify whether the predefine data sources could fit your needs, if there is no one available to use for you,
I would suggest you to implement a custom data processing extensions according to your own needs, you can refer to
Implementing a Data Processing Extension
to learn how to implement a data processing extensions.

Consume oData service in WebDynpro ABAP

Hi All,
Is it possible to consume a oData service from one SAP system in to another system (assume in a report program or WebDynpro application)?
If yes, can you please guide me?
Thanks in advance....
-Chandra

Hello Chandra,
Do u have a scenario/requirement where u want to consume a GW Service from WebDynpro screens ?
Is it really required ? if at all you want to consume GW service from WebDynpro screens, i think using GW is not a correct solution.
There would be some other ways to consume your Back-end business logic from WebDynpro screens.
I don not know if we can call GW Service in a WebDynpro screens. Technically if its possible also then i think its not correct to do that.
In my opinion GW has to be used in combination with UI5 for light weight applications.

Ashwin
