Vendor survey process

Hello,

I have two questions.

1: What steps do I need to take to be able to fill in a questionnaire at the moment a receipt confirmation is entered in SRM (5.0).

2: We would like to send surveys to suppliers. My understanding of the process is that this needs to be done via transaction BBP_EVAL_SURVEY. The supplier than receives an E-mail with a link where he can fill in the survey. When he fills the survey, what happens with the data? Is it (or can it be) moved to Business Warehouse or is it stored elsewhere?
