User Exits ​

abap2UI5 offers predefined user exits for tweaking the standard behavior. The interface Z2UI5_IF_UI5_EXIT exposes the user exits. To use them on your system, build a class that implements the interface and its methods. The abap2UI5 class Z2UI5_CL_UI5_USER_EXIT calls them dynamically. Put your class in a custom package — not in the abap2UI5 packages.

The interface exposes two exit methods:

  • set_config_http_get — called on the initial HTTP GET request (page load). Use it to set frontend properties like the UI5 theme, the UI5 version, or the inline CSS.
  • set_config_http_post — called on every later HTTP POST request (each roundtrip). Use it to set backend behavior like the draft expiration time.

Both methods take a cs_config changing parameter whose fields you can set as needed. The example below changes the theme and how long the backend keeps drafts:
