How can I set the background color of WebDynpro?
In the application parameter give wd_theme as parameter and give the path of standard theme.That standard theme will be mime repository.The path may be like this sap/mime/tradeshow
Then run your application it will display the views in tradeshow
If you want to customize the standard theme just refer the wiki
I did the customization of theme editor and called it into R/3
it is possible.
