You can extend the functionality of SAP Fiori X1 and X2 apps by enhancing some of the content layers. The criteria for determining whether or not you need to enhance a layer are described in the following table:
Content Layer |
When an Extension is Required |
Relevance |
---|---|---|
Business Suite |
The back-end logic and content required for the application enhancement does not exist in the Business Suite. |
Extensions in this layer are not covered here. Consult the app-specific documentation. |
Gateway |

Extensions in this layer are not covered here in detail. For more information, see Extending the SAP NetWeaver Gateway Layer. |
UI |
