Client Requirement: stop depreciation for some of fixed asset for maybe 3 months,it means no depreciation posted to those fixed asset during the period of shutdown.
Go for shut down approach. But your depreciation key should allow shut down.
Check your depreciation key configuration
In asset master data - Go to time dependent terms,
Define the appropriate time interval for shutdown - Set the shutdown indicator
The system does not calculate the depreciation for the shut down period,
The useful life of the asset will increase to the extent of shutdown period.
When you remove the shutdown indicator, system automatically resumes the depreciation calculation.
