Supplier Creation via ROS Problem

Hi Gurus,

I'm trying to implement ROS scenario with SRM 7.01-SUS different clients. I've made appropriate settings for both SUS and SRM side. But i'm facing a problem while creating the supplier at SRM side(via manage business partner transaction) reference to approved supplier. System succesfully transfers the supplier via OPI but when i try to save the supplier, system gives an error message "Enter the logical system". I checked all obligatory fields in form and customizings but couldn't find an error. Is there anyone who knows the solution?

Regards,
