选择默认为今天日期的选项？

Question

我试图在选择日期中将今天的日期显示为默认值。

INITIALIZATION.
select-OPTIONS: so_date FOR sy-datlo.
START-OF-SELECTION.
so_date-sign = 'I'.
so_date-option = 'BT'.
so_date-low = sy-datum.
so_date-high = sy-datum.
APPEND so_date.

这不是工作虽然。什么好主意吗?

Answer 1

必须在START-OF_SELECTION:

select-OPTIONS: so_date FOR sy-datlo.
INITIALIZATION.
  so_date-sign = 'I'.
  so_date-option = 'EQ'.
  so_date-low = sy-datum.
  CLEAR so_date-high.
  APPEND so_date.

你有没有试过简单的版本:

select-OPTIONS: so_date FOR sy-datlo default SY-DATUM.

我认为它应该工作(不能测试是实际的)。
