Hi Ravan,
After run AFAB in repeat mode for 2014, close the year 2014 in AJAB after that you can run depreciation for last period in repeat mode and from current period on wards run it in planned mode. Suppose if you have run depreciation for 2015, up to Feb month, then you can run Feb month in repeat mode and March month in planned mode. However, if you have not run any depreciation for 2015, then you can run from the start of month of 2015 in planned mode.
Regards,
Mukthar
