Balance carryforward Run & subledger- ByD

Hi gurus

I executed the Balance Carryforward Run to close 2014, and the accounts were correctly transferred to 2015, but for the AP accounts, in 2015 there's no assigment to the subledger accounts of every ID supplier.

The total amount appears as "Not Assigned" in Business partners column of the G/L Accounts- Line ítems report for 2015.

So, the Balance Carryforward is not able to transfer the subledger accounts?? Or do I need to execute another Closing cockpit activity for this??

Many thanks
