demo services available in ES5 demo system

[MartinMaruskin]

Hi,

I'm working with demo system ES5 of SAP NW Gateway. I obtained an account to that system via page https://register.sapdevcenter.com/SUPSignForms/
What is strange to me is that I do not see any demo services available in SAP Gateway Service Builder (tcode SEGW).
Does anybody have an idea how to try out any service in there?
thanks

Have you tried if you see the services at: https://sapes5.sapdevcenter.com/sap/opu/odata/IWFND/CATALOGSERVICE;v=2/ServiceCollection?$format=jso... ?

hi Gregor,

Thanks, yes CATALOGSERVICE is working for me. However, my issue is how to see services in tcode SEGW while logged into ES5 system via webgui. When I attempt to go into that tcode I see none projects (see pic). Am I just not authorized to see any service in the tcode? If so what is a purpose of it? In my case, I'm interested in a definition of the services, code behind them etc.

cheers

I do not even have authorization to start the transaction. I would suggest to give https://github.com/hschaefer123/odataexplorer a try. Configure the ES5 system as a destination in SCP and deploy it as a HTML5 app.

ok thanks, based on this I assume the SAP Gateway demo systems such as ES5 mostly serves a purpose of being consumed in other apps.

Anyhow, thank you very much for your help!

Can you perhaps elaborate about your intended use case?

I wanted to explore existing Gateway services that are delivered with the system like LORD_ODATA_ORDER. I wanted to see how classes/methods retrieving data in the background are coded etc. Basically for this would need an access to SEGW tcode (which I have) and also be able to display projects/services etc. Unfortunately, match code search in the SEGW doesn't display any projects. I assume this is due to authorization setup.

I guess LORD_ODATA_ORDER is a OData Service provided in SAP CRM or SAP ERP. So the ES5 System which is a pure NetWeaver ABAP without any Business Suite content will not help you. If you don't have access to a corporate system you might use https://cal.sap.com/ to spin up your own system. There is also a SAP CRM 7.0 EhP4 available.

Thanks Gregor. I checked and yes the LORD_ODATA_ORDER service is delivered via dev package ERP_SD_ODATA_SLS (OData Services for Sale)so this is definitely delivered within application packages like ERP.

Now perhaps an additional question. The NW Gateway has standard "example" kind of thing service called GWSAMPLE_BASIC. Shoudn't this service be visible in the SEGW?

thanks

On the ES5 system it is an authorization issue that you can't open /IWBEP/GWSAMPLE_BASIC in SEGW. So perhaps also the NetWeaver ABAP Developer edition that you can download from https://tools.hana.ondemand.com/#abap might be an option.
