Question on BPFin BPC

Dear Experts,

I am new to SAP BPC.

I am Doing a project. I Need help.

I have Three users 1) Sr.Sales Manager 2) Sales Manager and 3) Sales Executive.

I have created a three BPF's for each user.

I am assigned a Sales infomation input schdule in Sales Executive's BPF.

Once the Sales Executive enter data in to Sales input schedule & this sales nput schedule should be approve by Sales Manager and same sales input schedule should be forward to Sr.Sales Manager for his approval.

How can we forward reports or input schedules from one user to another for approval and finally store in Database.

Please help me.

Thanks a lot in advance,
