Budget Report

Hi All, Thanks in advance for your help! I am using the MSP 2007 and want to get a Budget Report using template reports, "Budget" under "Cost Reports". The problem is if you pick "Period:Week" or any other period other than "Entire Project" budget of those activities that go more than the specified period is shown similar in each period rather than uniformly split it between the periods. The cost accrual is defined to be "prorated". There is no problem to get "Cash Flow" report or even "Budget Report" selecting "Entire Project" period. I am looking forward to getting your help. Thanks, Mike
