I'm using SM59 RFC connection to do the communication between SAP system and external system. My URL is ：https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential≈pid=APPID&secret=APPSECRET. The ‘APPID’ and ‘APPSECRET’ is different every runtime. I wrote 'https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential' into the Host name. However, I have no idea of how to dynamically add the postfix. Do you have an idea?
Thank you in advance.
