Various framework extension points are available for list reports and object pages.
Make sure you have read the following information: Read Before Extending a Generated App.
Use app extensions with caution and only if you cannot produce the required behavior by other means, such as manifest settings or annotations. To correctly integrate your app extension coding with SAP Fiori elements, use only the extensionAPI of SAP Fiori elements. For more information, see Using the extensionAPI.
After you've created an app extension, its display (for example, control placing, CSS) and system behavior (for example, model and binding usage, busy handling) of the app extension lies within the application's responsibility. SAP Fiori elements provides support only for the official extensionAPI functions. Don't access or manipulate SAP Fiori elements' internal coding.
You can either use the extension wizard in the SAP Web IDE to create extensions or you can create them manually.
SAP Web IDE is no longer available via SAP Business Technology Platform trial accounts. Any references to SAP Web IDE in this documentation are only relevant for you if you have access to SAP Web IDE through a productive SAP BTP account. Please consider SAP Business Application Studio as an alternative. See App Development Using SAP Business Application Studio.
