advanced reporting help

Good day SSRS experts,

I am looking for guidance to create drill down reports. I am converting from Crystal to SSRS. It has multiple headers, group headers, 2 details panel and group footer. 

I can create a simple report using wizard (running a query and displaying all columns). I can't wrap my brain around following

• Each item line with contract (group by)
• Summary of each contract
• If a new contract is coming at end of the page. Must display at new page (Where I can find this settings).

Could you please guide how I can achieve above functionality. 

Thanks

Raj
