Back date the in service date of an asset GL date Functionality in R12

Hello 

We setup an asset in 11i in Feb-12 with an in-service date of 01-Jan-2012.  In 11i, when FA is closed jan-11 and the accounting is pushed through, the two months of depreciation gets posted in Feb-11 and transfer data to GL In 11i.

When we ran the close process and the accounting in R12, it didn’t complete the accounting for this new asset and showing error The GL date 01-JAN-2012 is not in an open or a future enterable period.  Please select a valid GL date or open the period.

We want to know any process or functionality change in R12 relating to above situation.
