Hi Sen,
please refer to this documentation http://help.sap.com/saphelp_erp60_sp/helpdata/en/ad/d64842d59fb430e10000000a155106/content.htm?frameset=/en/d5/581ee8d56f1247bf34cfcd66d16d81/frameset.htm
for configuring extended notification with UWL. The result will be that the links in emails will forward the user to the UWL rather than the SAP GUI.
Best regards,
Sergei
