对于非选择屏幕的情况，RFC接口输入数据后，如何处理字符串模糊查询、日期区间查询、数字区间查询：

一、所有字符支持模糊查询，在SAP SQL中，使用 %S%来实现。

二、区间查询有3种情况：

1、没有值输入，程序需要填入最大上下限

BETWEEN  20200101  TO  99991231

2、输入单个值，如20240930，代码中在BETWEEN,TO两个字段填入

BETWEEN  20240930  TO  20240930

3、输入两个值，如20240901-20240930代码中在BETWEEN,TO两个字段填入

BETWEEN  20240901  TO  20240930

注意，在UI端要检查一下日期是否合法，数字区间要规范成0
