Asset at Year End Closing Error

Hi Team,

My company new fiscal year starting 01.01.2017 have done these and error

1- AJRW - New fiscal year = 2017

Error - Fiscal year change in co code possible only after year end closing 2015

2- AJAB - Fiscal year to close = 2015

Error - Depreciation not posted completely

3- OAAQ - 2014

I have some assets depreciation which the run should take place in YR 2015 period 12 but it didn't happen and we have run it using unplanned depreciation in YR 2016 period 6 for the YR 2015 period 12 depreciation for certain assets.

How am I suppose to make it success to year 2015?

Thank you.
