Role of SAP Gateway OS process in handling ODATA calls

[former_member245487]

Dear Team,

First of all, I am very new to the Gateway and ODATA services.

I would like to understand how the ODATA calls are handled by Netweaver systems from Firori launchpad application perspective.

In most of the guides, we never talks about the Gateway process, below is my understanding about the connection flow, Is this correct?

Fiori Launchpad (SAP UI5)  --> ICM --> Gateway service (OS processes) --> Gateway

ICM calls to Gateway registered programs is handled via Gateway services, right?

Thanks,

Razal

Hi Razal,

we never talk about the Gateway process because there is no Gateway (OS) process involved.

From the SAP Fiori Launchpad OData Services are called in the SAP Gateway Hub System (aka Frontend Server).

The app itself will also call an OData Service hosted in the SAP Gateway Hub.

After hitting the ICM the SAP Gateway Framework (in ABAP) will be called. Then there is an RFC cal to the SAP Business Suite Backend calling the SAP Gateway Backend Framework (IW_BEP).

Then finally your ABAP Classes in the SAP Backend are called that contain your Service implementation which finally retrieves same data from the underlying database.

Hope this helps.

Best Regards,

Andre
