Thanks for your reply ..
I would be using this custom theme for many ITS services.
Shall I create new theme under "WEBGUI", example, Topic HR ? Rather creating "Theme" and "MIME" separately, I have copied "Topic SL" into "Topic HR", is that correct ? I have to copy one of existing theme and then do modifications.
What next and how to change theming ?
One more question ..
/sap/bc/gui/sap/its/webgui/!?~transaction=ZXYZ&~theme=sap_corbu ... shows the service in "Corbu" theme and path of css appears as "/sap/public/icmandir/its/ls/themes/sap_corbu/ls/ls_ie6.css", in similar way how do i create a theme called "cust_theme" ??
Thanks
