Hi,

I want to provide a hyperlink on my search results..So followed the below steps..for Sales Order, th ehyperlink should open VA03 from ECC system

1. configured a Field for USer profiles for SO_NO (Sales Order)  and changed Drill down type to 'S Drill Down to SAP system'

2. Assign  Link to confiugre Field

     a. Assign Business objects - YSV_SO_NO  - BUS2032(Objetc Type), Display (MEthod) and Applciation Object (Logical System)

But when i click on the hyperlink on portal I get the error "Target SAP system not found  Please check the customizing for the link and the customizing for the RFC connection"

Please let me know what else i need to check.. Although the RFC conenction are  all set correctly..
