Hi
Refer note 29694. It offers a program using which you need to delete the Planned (but not posted) depreciation in 2015. Basically, it will make Actual Posted Dep = Planned Dep
For the Ord Dep Start Date which is 5 months earlier than what you want, it simply means you have charged the depreciation more. If your depreciation is based on Useful life, you should ideally change Dep Start Date in Asset Master, after closing the Year 2015 in AA. This should adjust the depreciation in subsequent months. I feel this should be done, rather than ABZU
