Assigning system to package

Hi all,

I have imported MSS package in my EP6.0 system.

I have created one system using dedicated server template for R3. Created alias and done user mapping. In system test connection I am able to connect to the system.

The problem is when I open the My staff page it says could not connect to R3 system. The error says could not connect to sap system SAP_r3_humanresources. This is not the alias that I have created. I have created STB as the alias I want to use.

How do I assign this system to the package.

Please guide me.

Thanks and regards,

Afroz
