Hello Tarak,
You would followed the below methods to settle a CWIP to Final asset.
1. AIAB and AIBU
2. KO88
3. CJ88
Check the settlement date and month and do the settlement reversal on the same date and month. So that, there will no depreciation posted.
1. AIBU - Menu bar -> Environment -> Reverse
2. KO88 -> Menu bar -> Settlement -> Reverse
3. CJ88 -> Menu bar -> Settlement -> Reverse
Make sure, the settlement period and dates are the same of initial settlement.
Hope this helps
