User Exits

abap2UI5 offers predefined user exits for tweaking the standard behavior. The interface Z2UI5_IF_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_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 page title, UI5 theme, or UI5 version.
• 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 title, the theme, and how long the backend keeps drafts:

CLASS zcl_a2ui5_user_exit DEFINITION PUBLIC.

  PUBLIC SECTION.

ENDCLASS.

CLASS zcl_a2ui5_user_exit IMPLEMENTATION.

    cs_config-title = `my title`.
    cs_config-theme = `sap_belize`.

  ENDMETHOD.

  METHOD z2ui5_if_exit~set_config_http_post.

    cs_config-draft_exp_time_in_hours = 8.

  ENDMETHOD.

ENDCLASS.
