Hi Ragavie,
Have you added the odata components? We have the UIX* components and the SR* components.
I would suggest to follow below link to get the details of app specific addons.
SAP Fiori - Add-on quick reference for transactional apps
Also, please follow the steps as described in the installation guide.

Configuring SAP Provided oData services

Hi All,
I saw that sap has many pre-delivered many oData services.
SAP NetWeaver Gateway Supported OData Channel Scenarios - SAP NetWeaver Gateway - SAP Library
Has anyone configured them and got to work?
I have a Hub Scenario and see that IW_CNT is a requirement for each of them. Configuration guide says that this is a component to be installed on the HUB server. Does it mean that DPC and MPC are going to be in the HUB for these scenarios? What if I want MPC DPC to be in backend ?
Any experience or comment is welcome.
Thanks
Krishna

Hi Krishna,
Atanu is right. You either need to deploy either IW_CNT on systems prior to 7.40 and IW_FNDGC on 7.40 systems in the Hub.
The services themselves are in maintenance mode and are not developed further. That's why they have been packed in 7.40 in a separate AddOn and are not shipped as part of the 7.40 standard.
This is because we (SAP) do not plan to ship content via SAP NetWeaver Gateway but rather are shipping services as part of complete solutions such as SAP Fiori.
Though the customer can use the services I would recommend to develop your own services instead (the BAPI's hat have been used are listed in the SAP Online Help).
Another option if no development is wished would be to have a look at the applications that we are shipping with SAP Fiori.

Andre

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,
Srinivas.

Hello @Nrisimhanadh_Yandamuri
Thanks for your reply..
I have got all the required authorization.. But still I am not able to hit the service.. Please let me know what could be the solution..
Thanks,
Srinivas.

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

UI5 Approval - Missing OData Service TASKPROCESSING

Hi Experts!
We are implementing SAPUI5 HR renewal Services with NW 7.4 and EHP7.
When we execute the approval applicaton, we are facing the following error message:
The error log shows that the TASKPROCESSING Service is missing:
I've checked already the following help-document:
http://help.sap.com/erp_hcm_ias_2013_02/helpdata/en/53/c46f8fc17a45088235db354b070a6e/frameset.htm
We activated all the business functions. But indeed, the oData Service /IWPGW/TASKPROCESSING is missing (or at least not activated yet).
When I try to add this Service via /IWFND/MAINT_SERVICE, there is no search result:
How can we add / activate this service?
Thanks in advance!

Please advise if you are using this on portal or NWBC?
Looks of it you are using the portal, did you assign the correct portal and backend UI5 role?
did you check the ping to the BPM webservice ? does it work?

Change system alias software version to /IWPGW/BWF
Now the service should run ,
Check in transaction /iwfnd/gw_client
Do GET on url - /sap/opu/odata/IWPGW/TASKPROCESSING/TaskCollection
The previous error should be gone
then send me the response and error log if exist.
If you see in this transaction a good response, then most likely the

OData Service Internal Server Error

Hello,
I developed SAP Netweaver Gateway Odata Service and I get "Internal Server Error" 500 on READ Operation. BAPI Itself does function well.
Where could be the problem?
Regards
Vladislav

Hi Vladislav,
You will get further information about the nature of the error by checking the error logs in the server(s), tcodes /iwbep/error_log and/or /iwfnd/error_log. If you have an embedded GW server, look in the /iwfnd logs.
You may find the list is blank until you use the 'Re-select' button and change the settings, so don't assume there are not errors to see!.
Make sure you have full trace access settings configured in views /IWFND/V_LOGV and /IWBEP/C_LOGV. These views are normally empty, there are two possible new entries that can be made and the possible values are on the F4 lists.
If this is a data translation error, you won't get a direct answer from the log but it can be used to pin down the nature of the exception.
If you can get this far, I can point you on to a technique for analysing the error during runtime - but it needs an error log result to be able to relate to.

Ron.

Getting error while quering the odata service

Hi Everyone,
I have used "Query Service(Method => EMPLOYEECOLLECTI_GET_ENTITYSET)" for update data to backend system and I have written logic in that method from the below link:
http://scn.sap.com/community/netweaver-gateway/blog/2014/03/06/let-s-code-crudq-and-function-import-operations-in-odata-service.
But when I test in SAP NW Gateway Client I am getting below error
Browser showing below output/error
Kindly help me on this
Regards,
Soumya

Hello Sowmya,
It cannot happen that GW is throwing EMPLOYEECOLLECTI_GET_ENTITYSET is not implemented even after you have written code in that method by redefining it.
I could see that you are raising an exception in the code shared by you here . i.e.,
RAISE EXCEPTION TYPE /iwbep/cx_mgw_not_impl_exc
    EXPORTING
      textid = /iwbep/cx_mgw_not_impl_exc=>method_not_implemented
      method = 'EMPLOYEECOLLECTI_GET_ENTITYSET'.
Please remove above code and return your response as below.
copy_data_to_ref( EXPORTING is_data = et_tab CHANGING cr_data = er_entityset )
where et_tab is your local table where you would have stored the results which you intend to send back to GW. i.e., et_entityset in your case
Activate DPC class and check.
This should resolve the issue

Ashwin

Access cloud for customer Odata Service from HCP

Hi
I have a UI(sapui5) which consumes ODATA Service from "cloud for customer" system.
I am using connectivity proxy servlet(using destinations) to avoid cross origin issue. when i deploy and access this UI from cloud, the response of the odata service is " HTTP status 500 javax.net.ssl.SSLPeerUnverifiedException: peer not authenticated".
I tried giving the http url and that says "502 bad gateway".
How to resolve SSL issue for cloud.?
Is there any other configuration that needs to be done to consume ODATA from "Cloud for customer" system
Regards
Priyal

Hi Priyal:
For the SSL handshake at the destination level either you would have to set the property "TrustAll=TRUE" or you have to create a JKS keystore which contains the Server Certificate for the Cloud for customer system and then upload this either via the Admin cockpit (at destination level) or deploy the same via the NEO console tool.
Best regards
Venki

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

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
http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/f0efbaca-45ba-3010-b7bb-8c1c5aa109ab?QuickLink=index&overridelayout=true&58475979909212
Other than setting up the Netweaver gateway, is it possible to achieve it through GWPA(eclipse plugin). I am using the kepler version of eclipse. Could you please share the documents related to this topic?

Hi Jitendra,
I have developed ios/android applications using SAP Mobile Platform SDK 3.0 SP06.
1) MAFLogin is successful
2) Store initialize is successful
Now I have to fetch subset of data from the database table based on some conditions.
Could you please help to clarify the below queries?
1) Is it possible using eclipse plugins?
2) Can we achieve this feature only through Functional import feature using SAP NetWeaver Gateway Service Builder?

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

Manage multi-table insert using OData Service
Where can I see logs of OData Service usage?
in aforesaid discussion they have said plz give path to xsa:<package path> but when i go to database trace config there is no option where i can give the path so please help...

In the database trace / trace configuration dialog: first be sure to check Show All Components. Then in the input box at the top of the dialog type xsa:<your package>. You can type just a partial package name as well and the search will find all matches.

when i trying to directly execute the same service using Google chrome it gives me data. But if the same service i was trying using the eclipse i got this message. Can u please tell how to create object for the oModel or is there any other thing that i have missed, One thing i was noticed here that automatically $metadata is appended in the service while calling and how we can overcome this problem.
