Creation of Odata Service

Hi Everyone,
I have created an Odata service which is related to Products. But while calling it from eclipse using NetWeaver Gateway no data is coming to the output.
Kindly help me in this matter that why no data is coming.
Regards,
Soumya

CAn you please try checking the same URL again in the browser ,(install a RestClient / JSON view extrension in chrome/firefox) to see if any data is being fetched
on the application side - please try disabling web security in chrome as per below
1)For Windows... create a Chrome shortcut on your desktop.
Right-clic > properties > Shortcut
Edit "target" path :
"C:\Program Files\Google\Chrome\Application\chrome.exe" --args --disable-web-security
or
2) type below command in Windows RUN
chrome.exe --user-data-dir="c:/temp/chromedev" --disable-web-security
and try running the same application again.

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:
Execution failed: HTTP status code is [401], expected [200]; response body is [<html><head><title>Logon Error Message</title><META http-equiv="Content-Type" content="text/html;charset=UTF-8"><style type="text/css">body { font-family:tahoma,helvetica,sans-serif;color:#333333;background-color:#FFFFFF; }td { font-family:tahoma,helvetica,sans-serif;font-size:70%;color:#333333; }h1 { font-family:tahoma,helvetica,sans-serif;font-size:160%;font-weight:bold;margin-top:15px;margin-bottom:3px;color:#003366; }h2 { font-family:verdana,helvetica,sans-serif;font-size:120%;font-style:italic;font-weight:bold;margin-top:6px;margin-bottom:6px;color:#999900; }p { font-family:tahoma,helvetica,sans-serif;color:#333333;margin-top:4px;margin-bottom:4px; }ul { font-family:tahoma,helvetica,sans-serif;color:#333333;list-style-type:square;margin-top:8px;margin-bottom:8px; }li { font-family:tahoma,helvetica,sans-serif;color:#33333;margin-top:4px; }.emphasize { color:#333333;background-color:#C8E3FF;padding:5px;}.note { color:#CC6600; }a { font-family:tahoma,helvetica,sans-serif;text-decoration:underline;color:#336699; }a:visited { color:#001166; }a:hover { text-decoration:none; }</style></head><body><table cellpadding="0" cellspacing="0" border="0" width="100%"><tr><td><h1>Anmeldung fehlgeschlagen</h1><br><h2>Was ist passiert ?</h2><p>Der Aufruf der URL http://10.5.1.150:8000/sap/opu/odata/sap/ZCM_TEST_V5_SRV/PayrqSet/ wurde aufgrund fehlerhafter Anmeldedaten abgebrochen.</p></td></tr><tr><td> </td></tr><tr><td class="emphasize"><strong>Hinweis</strong><br>Die Anmeldung wurde im System GWD ausgeführt.

Issues with ODATA service creation

Hi Gurus,
I am facing some issues with ODATA service creation. I have an analytic view which I want to consume via SAP UI5.
As per guides and blogs, I need to create 3 files, namely .xsaccess, .xsapp and .xsodata. I created these three files but at the same time .xsodata and .xsaccess got created at one more place. That place is my package which I checked out while creating the repository. Now when I try to activate my .xsaccess or .xsapp file, I get an error message - "The file name .xsaccess or .xsapp already exists and only 1 file is allowed per package"
for more info please revert.
Kindly help.
Best regards,
Chandan

Can we add multiple analytic views in one ODATA service?
Certainly. You just have multiple entities then. You can even create associations between them. Here is an example that uses a combination of CDS Views, Attribute Views, and Analytic Views:
service namespace "Wile.services" {
"Wile.data.models::AN_EPISODES" as "Episodes"
keys ("EPISODE_ID")
navigates ("ToACMEItems" as "ACMEItems",
            "ToCoyoteNames" as "CoyoteNames",

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:

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.
Regards,
Juergen

Error while creation of web service model in web dynpro

Hi,
I am getting following error "no services available or local server not accessible" while creation of web service model.
I have already created my web service nad deployed it. It was deployed successfully.
In the web service model creation wizard I am not able to see neither my web service nor any other standard service.

Are you using the deprecated Web Services model or the new adaptive web services model?
Take a look in this document: https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/b2bc0932-0d01-0010-6d8e-cff1b2f22bc7

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..

Iam getting the below error while accessing the data using odata service.
"Failed to load resource: the server responded with a status of 404 (Not found)"
"No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin "
i have tried all the solutions like changing the url pattern "proxy/htttp".
and disabled - security in chrome (Chrome is Updated version).
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.

Lars

Query relating to the creation of Managed Service Accounts

Hi Folks
I am studying for my 70-411 exam and have a query relating to the creation of Managed Service Accounts.
I have successfully created an MSA account named 'MSATest' on a DC using:
new-adserviceaccount -name msatest –dnshostname home-dc-01 -passthru
and
add-AdcomputerServiceAccount -identity home-ap-01 -serviceaccount msatest -passthru
However the guide that I am using now says that I now need to run: Install-ADServiceAccount on the host computer in the domain to install the MSA in order to make available it available for use by services.
So on my member server (home-ap-01) I have installed the Active Directory Module for powershell and ran:
PS C:\Users\administrator.PCECORP> Install-ADServiceAccount -Identity msatest
Install-ADServiceAccount : Cannot install service account. Error Message: 'An
unspecified error has occurred'.
At line:1 char:1
+ Install-ADServiceAccount -Identity msatest
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : WriteError: (msatest:String) [Install-ADServiceA
   ccount], ADException
    + FullyQualifiedErrorId : InstallADServiceAccount:PerformOperation:Install
   ServiceAcccountFailure,Microsoft.ActiveDirectory.Management.Commands.Insta
llADServiceAccount
PS C:\Users\administrator.PCECORP>
However this errors, Have I misunderstood the purpose of the Install-ADServiceAccount ? or am I doing something wrong?
Thanks in advance for you help.

Try using -RestrictToSingleComputer parameter when creating service account with New-ADServiceAccount.
Gleb.
Hi Gleb
Thank you for your help, it is appreciated. That did the trick.
All the best.

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

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);
