Supplier PreScreening in Webdynpro UI for SUS 7.0 EHP 1

Hi Experts,

I logged into the SUS Client in portal with the role as "SUS Purchaser" to see the Supplier Prescreening and to transfer the supplier into ERP System. But the UI hangs and when I check in the transaction SM66 - I get a infinite loop in one of the SAP standard program.

If I loginto the BSP Portal using the same user ID - there is no issue in logging in. Please advice on the problem.

Thank you.
