Connect ABAP Backend to HCP via HCP OData provisioning

Following up on my article about the connection of a native HANA backend to HCP we will now have a look at the process about connecting an ABAP backend.

Motivation:

Previously you needed to set up an ABAP Frontend Server (Netweaver Gateway) to provide on OData service. The ERP Backend needs the IW_BEP component used for the development of the service. And via IW_FND on the Gateway system the service was made available.

With HCP OData provisioning you don’t need to set up a Frontend Server on premise any more. So this saves you one system in your landscape.
Here I will show how to connect the ABAB backend to the HCP without Frontend Server.
You still need the IW_BEP component and the development for the OData Service.

Disclaimer: This is for demo purposes only, security topics are not discussed here.

Prerequisites:

• You have activated you HCP account. (you can get a free trial via hanatrial.ondemand.com )
• The backend development has been done, or you use a ready made demo serivice.
• You have enable the OData provisioning service in your “Services” Menu.
• You have your Hana Cloud Connector set up and running as described in my previous post.

Lets Start:

We start by accessing the ERP Backend system.
in transaction SICF we check if the iwbep node is activated:

Right click and test the service to check if the activation was successful.

Also keep the URL in your notes:

http://<server>:<port>/sap/iwbep?sap-client=100

We switch to the Cloud Connector Admin Console

We add a new connection:

• Http
• Server and port of the ABAP system (from above)
• Virtual server (s4hanahost:8000 in my example)
• -no principal

Then we add a new resource:

• /sap/iwbep/

We also allow all sub path to be able to include more services.

Now we switch to the HCP Admin console:

We select Service->Odata Provisioning – Configure Odata provisioning

Here we define the Destination

The URL is:

http://s4hanahost:8000/sap/iwbep/ (according to the virtual host we have created)

The user is the ABAP Backend user

Additional property is the sap-client id

You may also need to configure the Roles for your user:

Then we switch to the actual Odata provisioning service in the HCP Cockpit:

The service is now registered:

From now on we can call it via the link “Open Service Document”

Based on this OData Service you can now create a UI5 Application as described in my previous post.

I hope you find this helpful.
