选择画面中有两个radio button，点击不同的radio button,显示不同的选择条件，并且做必输项检查，如下：
选择download，显示plant和sales Document两个条件
选择Upload，显示File name，
实现代码，
注意：屏幕字段必输属性设置时，要赋值2(screen-required = ‘2’.)，这样仅仅是外观显示有勾，当触发单选按钮的USER-COMMAND sel时，不触发系统的必输项检查。
REQUIRED各个值含义如下：
REQUIRED：控制文本框、下拉列表屏幕元素的必输性，使用此属性后会忽略OBLIGATORY选项。取值如下：
0：不必输，框中前面也没有钩
1：必输，框中前面有钩，系统会自动检验是否已输入，相当于OBLIGATORY选项
2：不必输，但框中前面有钩，系统不会检查是否已输入，此时需要手动检验
