如何给表维护视图创建选择画面
通常SAP系统中的表维护视图(sm30)把所有数据都显示在一个屏幕上，没有筛选，如下，左图是sm30,右图是SE11中的表数据显示。
如何要按条件进行筛选，要用到VIEW_RANGETAB_TO_SELLIST创建筛选条件内表，
例子程序如下：
简单介绍:
1, 先创建一个选择画面包含3个range ，s_id，s_name, s_place,
2, 调用VIEW_RANGETAB_TO_SELLIST创建sm30的筛选条件内表gt_seltab，三个条件之间是and关系。
3, 调用VIEW_MAINTENANCE_CALL显示表维护视图

运行结果：
选择画面输入筛选条件LONDON,
表维护视图只显示LONDON的数据。
以上。
