Fetching Data by Calling SAP Functions Without Parameters

Application Scenario

Your data is stored in SAP. However, due to data security concerns or limited knowledge of underlying tables in SAP, you find it hard to connect to underlying SAP databases for data fetching.

You want to fetch data by calling the developed functions in the SAP system for further data development and processing.

Function Description

FineDataLink allows you to fetch data by calling developed functions in the SAP system.

For details about parameter-based data fetching, see Data Fetching via Parameter-Based SAP Function Calling.

Call the API function to fetch country data from the SAP system, get data whose LANDX value is USA through filtering, and write it into a database.
