## 5.5 Integrating SAP Solutions
You can integrate several systems and services as part of the common business scenario. To do that, you create a formation in the SAP BTP cockpit that includes all systems that the scenario requires.
A formation is a logical grouping of SAP systems that can be integrated as part of a business scenario. Formations allow you to combine SAP solution systems to simplify the connectivity setup and to provide a unified view of all components required for the implementation of your integration or extension scenario. To create a fully functional formation, you have to include SAP solution systems. You do this configuration once and you can change it anytime.
See Automating Integrations Using Formations [page 2075].

## Integrate SAP Systems with a Service in SAP BTP
There are formations dedicated to automate the integration between supported SAP systems and a service in SAP BTP. In this use case the topology is a star topology where the service is in the center and is communicating with every SAP system that is included in the formation. The formation type is related to the service. The SAP systems that are included do not communicate between each other.
These are the formations types following this use case:
- Integration with Joule . See Enabling Joule [page 2096].
- Eventing Between SAP Cloud Systems . See Enabling Events Exchange Between SAP Cloud Systems [page 2091].
- Integration with SAP Master Data Integration . See Enabling Integration with SAP Master Data Integration [page 2094].
## Integrate SAP Systems to Achieve an Extensibility Scenario
Automated configuration allows you to extend SAP solutions without affecting their core functions. It also provides a central repository for APIs and data, ensuring easy access to services for developing extensions.
These are the formations types following this use case:
- Side-by-Side Extensibility with Kyma . See Setting Up System Landscape for Kyma [page 2098].
- Integration with SAP Build . See Setting Up System Landscape for SAP Build [page 2099].
