Reduce Useful Life of Asset

Hi Experts,

My User has an Asset whose Depreciation Start Date is 01.01.2016 and Life Time is 5 Years.

The Asset end date is 31.12.2020. Now the business has realized asset end date should be 31.12.2019 ié 4 years of life time.

When i am changing the Useful life to 4 years in AS02 the system is still showing some planned depreciation in the year 2020 in AW01N.

My Depreciation key is LINI .

Since the Asset Life will be over in 2019 , the user is not ok with certain planned depreciation in 2020.

Kindly help me how should i resolve the issue. There is no smoothening in OAYR for my company code.

Regards

Jalaj
