You can’t edit Net Book Value (NBV) directly. The Net Book Value (NBV) is a calculated. You can force amounts by entering a Beginning Accum amount (NBV = Acqusition Value - Beginning Accum).

 

Using the Beginning fields you can force the desired depreciation numbers. Any values keyed into the Beginning fields will automatically pull into the correct Current Depreciation fields.

• Beginning Date: Enter the month-end date depreciation you want the calculation to reflect. This will always be the end of a period. The system will resume calculating, if possible, in the next period after the Beginning Date
• Beginning YTD: Enter the current year to Date (YTD) Depreciation desired on the asset. This is the depreciation calculated in the Fiscal Year containing the Beginning Date
• Beginning Accum: Enter the Current Accumulated Depreciation from the Placed-In Service date to the Beginning Date

Important Notes:

• Reports show entered amounts in Current Accum and Current YTD. Depreciation This Run excludes those amounts. Create a journal entry to adjust the GL
• To force depreciation on assets with remaining life, change the Depreciation Method to RV. RV calculates the remaining value over the remaining life. This will ensure the assets will fully depreciate without a remaining Net Book Value. RV will negate any 168k Allowance for assets using a bonus method, such as MA or SB 
• Changing assets with existing Beginning information will overwrite previous Beginning information
• You can’t change Beginning Information on a Child of a Transfer. See Beginning Date is the only option when changing Critical Fields
• Assets won't appear on the Depreciation Expense report when you run depreciation before the Beginning Date. The asset continues calculating depreciation, if it has remaining life, beginning the month after the entered Beginning Date.
