Sales Assistant in Opportunity is Not working

Hi Experts

Little help pls

1. I created sales cycle and sales stage and assigned sales stages to sales cycle .

Where can I assign sales cycle to my opportunity type in IMG ?. is there any transaction code or IMG path ?.

2.Copied action profile 'opportunity sales assistant' and created Y_opportunity sales assistant and assigned this action profile to my opportunity type , also created action definition in action profile. Where and how I can link my newly created opportunity action profile to my sales cycle ?. So that I can choose activities in sales assistant in opportunity.

Thanks in Advance for your help
