Field help (STRADJDAT) 

This field is used to enter the start date for the variance adjustment on the depreciation total following a depreciation method change that has a retro-active effect.
It can be entered only when the variance management method has the value "Adjustment for the variance by plan". In this case, it is loaded by default, with the effective date for method change.
The entry date must be greater than or equal to the start date of the current fiscal year of the plan context.
