SAP S/4HANA In-App Extensibility with Real Time Business Scenario : Standard API Extensions and Integrations with Third Party Systems

[mohit_bansal3]

One of the most common Business requirement  in various SAP Projects is real time integration with commonly  used Business Context data with Third Party Systems such as:

• Product Master


• Sales Order


• Business Partner etc..

And common requirement in almost every integration scenario is posting / reading of data in above Business context along with few CUSTOM fields.

While working in S/4HANA Projects, Always first design approach came in mind why not to use:

"Standard S/4HANA API with In-App Extensibility”  &  " Every time It really worked like a Charm"

“Complete technical Solution were ready for testing in just couple days, Many thanks to S/4HANA with  In-App Extensibility and of course API Hub “ 😊

Bye Bye, Complex development and Let’s utilize power of S/4HANA with In-App extensibility and speed up our development  with standard API and integrate with any third party system😊

Business Requirement

Business wants to create Product, Sales Order data  in SAP S/4HANA  system and call will be made from third party system.

An example perspective, Product creation Standard S/4HANA with below custom Fields 

 

Development Architecture and Technical Solution

High Level Development Flow

Here is the typical Development Steps

• Identity the Business Context i.e., Material Master, Customer, Sales Order


• Check for Standard API in API Hub


• Extend Standard API with Fiori Extensibility Cockpit


• Added Custom fields via Custom Fields and Logic App


• API ready to consume by CPI with custom fields


• Fields are added in API CDS & BAPI and ready for consumption 😊

Let's build step by step complete technical solution 

 

Step1 : Identify the "Right Business Context and Right API"

As, We want to extend the Product then Business Context is Product and API is A_Product

• Visit the API HUB, select product S/4HANA and find the API


• Check the relevant API and find the respective end points for document posting, for example product creation


• Register the API in S/4HANA  /  Gateway System

 

Step 2 :  API Extension using the S/4HANA Extensibility cockpit

S/4HANA Extensibility Cockpit

Step3: Create Custom fields via "Custom Field and Logic"

'

Steps 4: Expose the custom fields for API( CDS A_Product) and BAPI for Product create.

Custom Fields are exposed for API and BAPI

 

Push “Publish” in the bottom-right of the screen.

 

 

 

Step5:

Cool. We are done.....Let's do the testing with POSTMAN  and create Product and custom fields are available

 

I have also quickly created the Fiori App consuming the "EXTENDED API END Point"  A_Product , just to show case how easy to create Fiori Elements based on the top of extended API..

Again Bye bye, Complex  technical development and Let’s utilize power of S/4HANA with In-App Extensibility  and speed up our development  with standard API and integrate with any third party system😊
