Hi Juergen and Sathish,
Thanks for the info, it turned out I forgot to create GI-ZONE in 9020. But I'm still wondering why there is no detailed log in SLG1 even after activating WT application log. Whre is the button you mentioned on the top of the screen? Is it from dropdown menu 'goto'? I checked there, still no detailed info.
Regards,
Jason
