Thanks GSR,
But I have done the migration to New Process, in a most simplest way.
A. Asset Accounting FY Closure for 2013. (TCODE - AJAB)*
(note : check for any unplanned reqd. to be posted, due to change in process.. Review & rectify the same. Take Asset History Sheet AR02 & Depreciation Report AR03.)
(My client has almost 70% asset, uploaded through Legacy Data Transfer, where it was difficult to change the Depreciation Key.. Hence A Process was adapted.
B. For all the Legacy, The Capitalization Date & Dep. Start Date modified to 01-04-2014 & Depreciation Key was updated to "LINR", useful life modified & saved the Master Record (Can be done through BDC / LSMW) along with Dep. Life Updated to YEAR & DAYS FROM old YEAR & MONTHS, (Asset Master Data Depreciation Area)
Once the Dep Key was updated to "LINR", restored the Cap.Date & Dep. Start date.
Checked for Correct Useful Life updated in Asset Master Dep Area (Report AR03). Checked the Correct, Depreciated Life also.
C. Once this was done completely, checked for the reports. Did the test Run. Reviewed the Dep Run ... the Values found to be absolutely matching as per the requirements of the Law, with a marginal variation in few assets (due to rounding off issue in SAP)
D. The Results were a success.
A Simple Process of Close the Previous Asset Accounting Period, Update New Useful Life as per New Companies Act 2013, Modify the Depreciation Key to "LINR", check the Dep. Posted Period. & the process is done successfully.
