[fmalv] 在对话框中使用alv显示明细

Twilight发表于 2014-08-12 16:31Twilight 最后回复于 2014-08-12 16:31 [复制链接] 4355 0

使用FM：REUSE_ALV_POPUP_TO_SELECT来实现这种对话框的选中效果。有时需要用函数REUSE_ALV_POPUP_TO_SELECT来显示一些数据，例如调用BAPI创建单据时，可以把错误信息用此函数展示出来。
alv中的对话框可以过配置FM的如下参数控制
i_screen_start_column = 10
i_screen_start_line   = 20
i_screen_end_column   = 100
i_screen_end_line     = 40
