Hi,

Refer below explanations from e-learning. 

Change Net Value

Explanation

This activity is used to set options for the change in net value.

Prerequisites

Before you can set options for the change in net value, the following must have been completed:

1. The object(s) must be fully depreciated up to and including the date for the change . This means that a change can only take place if the event date is at the end of a period. (Note: This prerequisite is not necessary if the object type of the object for which this activity is performed is Non Depreciable.)

2. System Effects

   As a result of this activity, options for the change in net value is set and the window Change Net Value - Progress is opened and the selected  object(s) is ready for change of value.

   Procedure

3. Open the Change Object Value window and query for the object(s) for which you want to change the net value.
4. Select the record(s) that you queried for, right-click and click Change Net Value.
5. Enter appropriate value in the Voucher Date, User Group and Voucher Type fields. The default values are displayed.
6. The Recalculate value gives an opportunity to insert a default value for selected object/objects. This could be done by percentage or amount. Select Percent or Amount as base for recalculation of acquisition value.
7. Use the List of Values to enter a value in the Depreciation Reason field.
8. For default values enter an quantity in Value. If Percentage is selected, this field holds percentage, and if Amount is selected the field holds amount. For percentage: -10 = 10% reduction and 10 = 10% increase. The base for calculating is Acquisition Value. .
9. Enter the event date. The object must be fully depreciated up to and including the event date. This means that a change can only take place if the event date is the last date of a period.
10. Enter the retroactive date; the date to which the transaction affected. Event date is the default value.
11. Click OK.
