SAP S/4HANA In-App and Side-by-Side Extensibility

Side-by-side extensibility with SAP Cloud Platform§ Integrate with SAP Cloud apps and third-party

solutions

SAP Cloud Platform: Extend reach. Integrate. IoT.

§ New standalone cloud apps(Internet of Things)

§ Extend core processes by beforeand after steps (for example,customer service or triggers fromsensor data)

§ Input from external users, mobility

In-app extensibility§ Variants of standard processes and business

logic (for example, micro-vertical solutions,localization)

§ Focus on company-owned businessdocuments (for example, legal compliance)

§ Analytics extensibility (for example, tailoredoperationalreporting for minimizedasset allocation)

1. Adapt UIsshow/hide/re-arrange/rename identifier of standard and custom fields

2. Create custom fieldsDefine custom fields and publish it for dedicated CDS views, APIs, UIsDDIC is automatically generated, CDS views and OData services areautomatically extended

3. Custom Analytics and FormsAssign defined custom fields for forms

4. Implement Custom Business Logic („BAdIs“)Implement business logic in ‘Restricted ABAP’; access custom fields,read other objects via CDS views; call external web-based services

Develop you extension in ABAP

• Define own data object structures(custom tables) and add businesslogic in ABAP.

• A Fiori UI can be automaticallygenerated and adapted with the WEBIDE

• Use business logic (e.g. BADIs) torun actions or validate the entries

• use your business object to createyour custom OData services(read/write)

• Maintain custom tile on Launchpad

• Associate to custom fields or othercustom business objects

Side-by-side Extensibility


A side-by-side extension is a customerdeveloped and operated application,running next to SAP S/4HANA

• De-coupled integration via APIs,events and replication services

• Lifecycle independent

• Separated application stacks

• Highly productive developmentenvironment with the SAP WebIDEand S/4HANA Cloud SDK

• Supports hybrid scenarios
