Error while releasing Cover Contract Commitment for the next year

Hi, 

We are creating a new Cover Contract Commitment for the year 2015 ,  while releasing the commitment we are getting the error " Contract Commitment cannot be opened for invoicing because there are no payment forecast in the current fiscal year"

The contract commitment period for the year 2015 is open. As well as the period in GL and AP .

Please suggest is there any year end activity to be performed before creating commitment for the year 2015.

Thanks in advance
