Summary :
When attempting a partial retirement of a fixed asset with period weighting at the end of its useful life, error AA641 "Net book value negative in area &" may occur. This error is triggered by the depreciation key formula, which uses the net book value and the remaining life. Since the periods are weighted, full depreciation may not have been achieved post-useful life, causing the system to reject partial retirement attempts. Solutions include adjusting the asset value date or revising the asset's planned or expired useful life in the master record via Transaction AS02 to circumvent this issue.
