选择选项中的多个排除值?

Question

我必须为材料组创建一个新的初始选择，并将排除的垫子组Z310和Z320设置为默认视图。但是，在需要时，用户应该能够包含Z320

selection-screen begin of block b4 with frame title text-b04.
select-options: s_matkl for t023-matkl default 'Z310'.
selection-screen end of block b4.
INITIALIZATION.
s_matkl-sign = 'E'.
s_matkl-option = 'EQ'.
s_matkl-high = 'Z310'.
s_matkl-low ='Z320'.
MODIFY s_matkl.

我尝试了上面的它不起作用。关于我如何做到这一点的任何建议？

提前感谢！

Answer 1

如果您使用的是较新版本，则以下内容更简洁一些：

DATA gv_matkl TYPE t023-matkl.
select-options: gt_matkl for gv_matkl.
INITIALIZATION.
gt_matkl[] = VALUE #(
( sign = 'E' option = 'EQ' low = 'Z310' )
( sign = 'E' option = 'EQ' low = 'Z320' )
).

Answer 2

试试这个：

data g_matkl like t023-matkl.
selection-screen begin of block b1 with frame title text-b01.
select-options: s_matkl for g_matkl.
selection-screen end of block b1.
INITIALIZATION.
s_matkl-sign = 'E'.
s_matkl-option = 'EQ'.
s_matkl-low = 'Z310'.
APPEND s_matkl. " <----------- 'APPEND' instead of 'MODIFY'
s_matkl-sign = 'E'.
s_matkl-option = 'EQ'.
s_matkl-low = 'Z320'.
APPEND s_matkl. " <----------- 'APPEND' instead of 'MODIFY'

需要时，用户应修改选择选项。
