Pipeline with more than one opportunities

Hi experts,

I have a requirement in SAP CRM 7.0 for  the pipeline performance analysis with different type of opportunities.

If I work with just one opportunity, i don't have any problema, but recently I created a different opportunity document,  with different sales phases, but when I try to see the Sales Pipeline Analysis, the report show all phases mixed (both documents).

Thanks a lot for yur help.
