ENDFORM. "Set_pf_status
此FORM的作用是在标准的ALV工具栏上添加自定义的按钮
该名称必须和FUNCTION 参数I_CALLBACK_PF_STATUS_SET = 'SET_PF_STATUS'对应起来,即FORM的名称和变量名称要一样.
GUI STATUS 'ALV_PF_STATUS'是自己定义的,因为自定义后会把标准的ALV工具栏覆盖,所以还要把标准工具栏复制过来.
方法如下:
T-CODE :SE90 Program Library-- GUI Status
program name:SAPLKKBL GUI Status:STANDARD_FULLSCREEN 标准的ALV工具栏名称,F8运行,选择菜单栏GUI Status---COPY,最后输入你的程序名以及你自定义的GUI Status名,此例即为ALV_PF_STATUS,再添加按钮.
