PMP Application - Is experience needed in each process area (not the process group)

Should we have experience in each process area given in the application.
Initiating has 5 processes so should we have experience in all these 5 processes, when I combine all my PM experience.
Or can I have ’0′ experience in one process area throughout my complete application say like in 'creating project charter'.

 As per my understanding, you surely do not 'need' experience from every process area.

I agree with rahultoraskar above.You are not required to have experience in every process area but  I think experience in the 5 domains is required.I personally had 0 hrs for creating project charter in all my  projects on my application.My application was approved with no audit. 

thanks for the reply rahultoraskar  and Have2passfirsttry.
