Solution Highlights

Use standard/Custom SAP ABAP objects for data extraction prescribed by SAP. E.g. BAPI, PROXY, ALE IDOCS, ALV reporting etc. (SAP customers commonly use such objects to report and analyze data.)
Customers deploy ABAP objects in their environments and retrofit them to their configurations.
In this case, SAP objects are scheduled to push. And, extract data outside SAP according to a defined schedule (Customizable).
Data required for additional mandatory objects is also captured in the enhanced objects. The ASP system may not be available in the SAP currently.
The ASP API selects the SAP system’s extract file. The scheduling engine has automated controls for this procedure. This is available as part of the ASP integration layer.
There is no manual involvement throughout the entire process.
