Hi,

While saving an Asset Mastter record the system is throughing me a warning message as " Different ord.dep.start date in depreciation area 15.Check"

Message no. AA186

The ordinary depreciation start date you entered is different to the ordinary depreciation start date 01.10.2008 determined by the system in depreciation area 1..

Can any one help me out how to resolve this issue.
