ABAP 刷新屏幕

1、用方法CL_GUI_CFW

cl_gui_cfw=>set_new_ok_code( 'p_ucomm' ).    "p_ucomm = 'REFRESH'

2、用函数SAPGUI_SET_FUNCTIONCODE

  CALL FUNCTION 'SAPGUI_SET_FUNCTIONCODE'EXPORTINGfunctioncode = '='EXCEPTIONSfunction_not_supported = 1OTHERS = 2.

两者皆可做到在PBO中刷新屏幕字段数据，用于单（双）击ALV数据后更新屏幕字段数据。

如果在PAI刷新屏幕也可用DYNP_VALUES_READ, DYNP_VALUES_UPDATE来刷新屏幕字段

*  DATA: lt_dynpupdate TYPE TABLE OF dynpread,
*        ls_dynpupdate LIKE LINE OF lt_dynpupdate." 设置需要更新的字段及其值
*  ls_dynpupdate-fieldname = 'ZXXXX'. " 字段名
*  ls_dynpupdate-fieldvalue = zxxxx. " 新值
*  APPEND ls_dynpupdate TO lt_dynpupdate." 调用函数模块更新屏幕
*  CALL FUNCTION 'DYNP_VALUES_UPDATE'
*    EXPORTING
*      dyname     = sy-cprog " 当前程序名
*      dynumb     = sy-dynnr " 当前屏幕号
*    TABLES
*      dynpfields = lt_dynpupdate
*    EXCEPTIONS
*      OTHERS     = 1.
