User Exits

abap2UI5 contains predefined user exits which can be used to modify the standard behavior. The user exits are exposed by the interface Z2UI5_IF_EXIT. To use them in your system you have to create a new class which implements the interface and its methods. They're called dynamically by abap2UI5 class Z2UI5_CL_EXIT. You should not include your class into abap2UI5 packages but in any other custom package.

The interface provides two exit methods:

• set_config_http_get — called during the initial HTTP GET request (page load). Use it to customize frontend settings like the page title, UI5 theme, or UI5 version.
• set_config_http_post — called on every subsequent HTTP POST request (each roundtrip). Use it to configure backend behavior like the draft expiration time.

Both methods receive a cs_config changing parameter whose fields you can set as needed. The following example changes the title, theme and the time drafts are saved in the backend:
