Exploring the APIs From the SAP Gateway Demo System

In the last article, I introduced common APIs used in SAP Integrations. Today's article is task based. In this task, I explored the APIs From the SAP Gateway Demo System.

Aim of Hand-on?

To understand the OData model

Business Scenario

In this exercise, I examine the GWSAMPLE_BASIC service. This sample service is based on the Enterprise Procurement Model (EPM). I want to use the APIs directly to find the customerID and the associate address data for the productID HT-1000.

Task Flow

In this exercise, I performed the following tasks:

1. Checked if the productID HT-1000 is available.
2. Got the Sales Order IDs to the productID HT-1000.
3. Found the respective customer for each order of the productID HT-1000.

Prerequisites

?Access to the SAP Demo Gateway system ES5.

Outcome After This Exercise

I checked whether OData APIs can be called up and that technical data, for example, the productID HT-1000, is available.
