Dear all,

 

I am pretty sure that browsers like Chrome and Firefox can render SAPUI5 mobile pages. However when we try to test our SAP UI5 mobile application from one of these browser we receive an image with that message printed on it.

Is there a way to get around this problem?

Hello All,

 

I've created the Gateway OData projects using Gateway service builder tool.Now the issue is when some other user try to open these projects or to be precise try to search these projects using F4 help,It doesn't populate the list and says "there are no entries".

 

When I search the projects,F4 Help displays only those projects which i have created.

 

Is this an authorization/roles issue or some settings required in gateway builder tool.

 

Any help would be appreciated.

HTTP 'PUT' request for Netweaver Gateway Service (OData) using JSON format

Hi there,

 

I am trying to update data using the update method of a Netweaver Gateway (OData) Service from SAPUI5 or the Gateway Client (that shouldn't matter).

 

So far I can only get a valid HTTP Response if I am using XML as the request body data.

 

Is it possible to use an HTTP request with a request body data using a JSON string instead of the XML string? If this can be done, what do I have to do before using the 'update()' method of an ODataModel object.

 

Best Regards

Patrick

OData JSON missing "innererror" object

Hi,

 

Does anyone know why the $format=json OData responses from Gateway omit the "innererror" object when messages are returned?  I am returning 4 messages from Gateway and all four can be seen in the atom+xml response, along with the lead message, but with JSON I only get the lead message.

 

I'm running GW 2 SP04.  Is this fixed in a later support package?

 

Many thanks,

GW Function Imports

Hi all,

 

So I have been trying to implement a function import for a certain GW service.

I followed SAP's guide to create my function import

http://help.sap.com/saphelp_gateway20sp06/helpdata/en/56/d0cc05b564411e841141f68294e29f/frameset.htm

 

And used OData's URI convention to try and call the function import

http://www.odata.org/documentation/uri-conventions

 

But no success at all, everytime I try this, I get a Bad Request as a response saying the resource could not be found.

Am I missing something? Is there any place I need to implement this function import further?

I was already wondering what the function would do without me having to program anything...

 

Thanks for the help.

Gateway Costing and license issues

Hi

 

I'm sure this has been mentioned / blogged before, but i've tried searching and can't find the document anywhere.

 

I'm sure there was a change in SAP Gateway license last year to that any existing user licences were covered by the deployment of gateway

 

So for example if i wanted to download gateway install it on one of our test systems this would be free ?

 

So long as any users already had SAP licences ? 

 

I'd quite like to have a go at setting up the following application.

 

http://scn.sap.com/community/netweaver-gateway/blog/2013/01/09/developing-the-sap-workflow-app-for-ios-setting-the-wheels-in-motion

 

But i'm not sure of the costs of downloading and installing gateway at the moment

 

If anyone from SAP could advise that would be much appreciated

 

Many Thanks

Hi Experts

 

I created a service and got my GetEntitySet and GetEntity created and tested using the Gateway Client interface.

 

Now I want to create and test my Create/Update/Delete methods.

 

In Gateway Client I want to create a POST HTTP request, but I haven't been able to find any information on the format of the request and how to code my method in ABAP.

 

Please anyone if you will please enlighten me on this

 

Tried to read a lot of other posts on the forums, but haven't been able to figure out what the format should be.

 

Best regards.
