Hi Subramanyam,
The service under default host -->sap/bc/webdynpro/sap/------you asked to to activate is already activated and when i test that service i get the below screen.
Also when i was scrolling i found many services deactivated and many lauchpad services also not activated.
such as apb_launchpad giving some error while testing i get below result .Is it related or i don't need to worry.
regards,
Prajakta
