ABAP dialog按钮置灰

要将ABAP dialog中的按钮置灰，可以使用以下代码：

在AT SELECTION-SCREEN OUTPUT事件中：

DATA: l_button TYPE REF TO cl_gui_button.
l_button = cl_gui_alv_grid=>mc_button.
l_button->set_enabled( abap_false ).

这将使按钮不可用。如果要使按钮重新可用，则可以使用以下代码：

l_button->set_enabled( abap_true ).

请注意，这只适用于SAP GUI中的ABAP dialog，而不适用于Web Dynpro ABAP或SAP Fiori应用程序。
