Tutorial: Extending Custom Business Object with Business Rules Logic in S/4HANA Cloud using SAP Cloud Platform Business Rules
Introduction
SAP ERP is used by most of the customers and it is extended and amended based on the specific need and requirements of their organization. Extension could be simple or complex depending upon the requirement, can span across few applications, can be new piece of ABAP code or modification of existing standard code. There have been new extension strategies with SAP S/4HANA. It is majorly separated as (a) In-App extensions and (b) Side-by-Side extensions.
As part of in-app extension (which is available only for SAP S/4HANA Cloud versions), all the extensions exist in the same S/4HANA system and there is no need for any remote communication between the app and the extension. One of the extension point is Custom Business Objects. You can try out the tutorials that are nicely compiled in this blog series from Ulrike Liebherr.
Side-by-side extensions are achieved using SAP Cloud Platform services. If customers are not able to accomplish their need from in-app extensions, then this is an alternate approach. Among various available extension scenarios, extension of business logic is one of them as there is always a constant need and demand to extend standard business logic to cater to ever changing policies which are very specific to organizations. Using SAP Cloud Platform Business Rules, customers can extend their business logic independent of the S/4HANA in a centrally managed repository and common entity model and lifecycle approach, with capabilities to communicate and deploy directly to S/4HANA system.
note: This extension is available from 1811 release of SAP S/4HANA Cloud
