The total payments are %1. The cost basis is %2. The amounts must be equal (8015,1)?

I am creating a leased asset with lease term as 4 and estimated life as 8.And i select payment scheduled id as quarterly payment schedule.

I want to create the lease for lease type operating.But when i am trying to save the page i'm getting a error showing "The total payments are 1000. The cost basis is 1333.333333333333333333333333333330.  The amounts must be equal. (8015,1) "."The total payments are %1. The cost basis is %2.  The amounts must be equal."

Any body any idea please suggest.
