Hi Arumugam,
Yes, you correctly uploaded the balances. After that you need to upload the GL balances in OASV. However, you have to maintain the dep.last posted period as 12/2014 in OAYC for the co.code. After done these when you run the AFAB for period 1/2015, then system will post the depreciation for Apr
2015. Like that you have to run depreciation every month end.

Mukthar
