如何在选择画面中创建动态的select-options
作者：互联网
1, 用到的函数，类方法
下面介绍一个能根据所选表字段自动创建动态select-options的例子代码，代码中用到了以下函数和类方法：
1， FREE_SELECTIONS_INIT：初始化动态选择画面
2， FREE_SELECTIONS_DIALOG：弹出生成动态select-options的字段选择窗口
3， FREE_SELECTIONS_WHERE_2_EX：转换数据格式，RSDS_TWHERE ==> RSDS_TEXPR
4， cl_alv_table_create=>create_dynamic_table ：创建动态内表
2, 例子代码
完整代码如下：感兴趣可以自己debug看看。

代码中用到了两个status：
1，DIALOG
2，13317
另外还要创建两个屏幕，200和300，
1，screen 0200
代码：
| 1 2 3 4 | PROCESS BEFORE OUTPUT. **--Set PF-STATUS MODULE STATUS_0200. PROCESS AFTER INPUT. |
2，Screen 0300
代码：
| 1 2 3 4 5 6 7 8 | PROCESS BEFORE OUTPUT. **--Set PF-STATUS MODULE STATUS_0300. **--Display data using custom controller MODULE DISPLAY_DATA. PROCESS AFTER INPUT. **--Handle button clicks MODULE USER_COMMAND_0300. |
3, 运行方法
运行如下：
输入表名后，点击options按钮选择动态select-options用到的字段，
然后进入下一屏，可以填入select-options的条件，也可以点击上面New field selection按钮添加或删除select-opions的字段。
最后，返回到初始选择画面，运行出结果，
以上。
