ROS Error while clicking on Pre-select Supplier link

Dear Experts,

We are using SRM 7.0 EHP2.I am facing problems in ROS. When I am clicking on “Pre-select Supplier” link then I am getting following EP error in trace file.

[EXCEPTION]
com.sapportals.portal.prt.runtime.PortalRuntimeException: Exception in
SAP Application Integrator occurred: Unknown system alias.
System Alias: \#39;SAP_SUS&\#39;,
User:              \#39;SRMADMIN&\#39;,
Reason: System Alias is not defined or permission denied for this user

We are having 2 different clients for SRM and ROS client

Following Logical System has defined

PH2CLNT500 – SRM Client

PH2CLNT700 – ROS Client

Following entries defined in SRM Client for “Define System Landscape”

Log. System     RFC            Sys. Type   RFC     Local   FI Valid     CI Connect  SLD Name   RFC Dialog       Sys.Alias

I had defined following configuration in ROS Client for “Define System Landscape”

Log. System     RFC            Sys. Type   RFC     Local   FI Valid     CI Connect  SLD Name   RFC Dialog       Sys.Alias

Kindly noted that i had defined EBP_SUS Sys. Type in ROS Client.

Kindly suggest me whether my settings are correct or not?

Thanks & Regards,
