今天我使用SAP ABAP development tools进行开发时，遇到下面的错误消息：
request to the ABAP back-end could not be processed, because your client installation ofBAP Development Tools is out of date.
Do you wish to update the client installation now?
点了Update Now后没有响应。于是Google了一番，发现关于ABAP Development Tools的下载和更新，应该到SAP这个官网链接上进行：
https://tools.hana.ondemand.com/#abap
里面有详细的说明。
