Fiori Hub Setup - NetWeaver Gateway Missing Services

[ginwene_rueda]

Hi,

We are currently setting up a central hub deployment of Fiori applications.

We already have the prerequisites like trusted connection and SSO, etc. between the ERP and Gateway Server.

We already installed the necessary Fiori and UI components, and all supporting SAP Notes are already been applied.

Unfortunately, we still can't assign services from ERP to our Gateway service.

How can we link our ERP oData services to Gateway service?

Do we need to activate the services on ERP and how (opu node on SICF is not available)?

Thanks,

Gin

Hi Ginwene,

Please follow the steps mentioned in the Fiori installation guide. It explains everything step by step.

Yes. There is instruction in the section 2.4.1 Configure App-Specific Gateway Services.

+ Select the backend system alias

+ Copy and past the external service name from install guide. Section 2.5.1 Gateway Services for Applications

Hi Masa,

We already tried getting services from the ERP system, using the alias and external service name.

Unfortunately, even if the alias was already configured we still can't get the services:

And to support that our connection was already configured with trusted and SSO:

Hi Ginwene,

What is the result when you select the get Services button?

Any error? or Success response with no data?

Probably you have not followed the gateway installation guide.

Have you executed those steps?

Hi Masa,

When I execute the get services, I don't get any data. No errors or warnings.

Thanks,

Hi Ginwene,

I would do "/h" and debug. It is all ABAP code, so you can find the root cause.

or

You can test the FM /IWBEP/FM_MGW_GET_MDL_GROUPS with RFC destination which pints to the ERP backend.

Hi Ginwene,

I have exactly the same your issue.

Hi Marco,

The issue was solved by adding roles to our account. The issue was mainly related to backend roles on RFC. The connection was there, but there were some missing authorization on our part.

Hope this can help you.

Thanks,

Hi there,

you need to first activate the services in ERP via SPRO under the gateway tab.

Then you need to make sure you have created an Alias in GW that references ERP.

Once have done that navigate to /IWFND/Maint_service click add new service, select the Alias you created and you should then see your services referenced from ERP.

Hi Shaun,

As you can see, our ERP system doesn't have a Gateway Tab cause we have a central hub deployment setup.

I assume you want us to activate the services on SICF, but since this is a back-end side, the /sap/opu namespace is not available. Which is very similar to this thread:

We also verified that our service is installed, via SPRO under:

HI Ginwene,

Have you created a trusted RFC from GW to ERP?

Have you been through section 5A of the troubleshooting guide?

Hi Jeremy,

We can't debug the OData service yet, since when can't find the services when we try to add them from the ERP system.

When we try to get the services from the ERP system, the fiori services are not listed, even though we have configured the right system alias to which the service should come from.
