This topic provides information about the elements in this window in Visma Net, such as fields, field values, buttons, and check boxes. In this window, you can create, edit, or delete depreciation books for fixed assets. Also, you use this window to select the posting book that updates the general ledger. All depreciable assets must be assigned to the posting book. You can also assign depreciable assets to multiple depreciation books, if needed. For more information about configuring fixed asset depreciation settings in Visma Net, see: [About depreciation of fixed assets](https://docs.vismasoftware.no/visma-net-erp/help/fixed-assets/manage-fixed-asset-depreciation/about-depreciation-of-fixed-assets/index.md) ## The window toolbar
Button Description
Calendar

Navigates to the Book calendars (FA206000) window where you can set up a calendar for the selected book.

You can set up a calendar for non-posting book only.
## The table This table displays all the depreciation books defined in the system and their properties.
Column Description
Book ID The identifier for the book, up to 10 characters.
Description A brief description of the book.
Update general ledger

A check box that indicates (if selected) that transactions recorded in this book are posted to the general ledger. The posting book uses the general ledger calendar structure.

Note

Only one book can be set up as the posting book.

For a non-posting book (with the Update general ledger check box cleared), you should set up a calendar structure in the Book calendars (FA206000) window (that opens if you click Calendar in the window toolbar).

Note

If a calendar structure has been already configured for a non-posting book in the Book calendars (FA206000) window, this book cannot be specified as the posting one. That is, the Update general ledger check box is not available for selection.
Mid period type

The rule defining the middle of the period to be used for averaging conventions.

The averaging convention, which determines how fixed assets will be depreciated for periods within which assets were acquired or disposed of, is selected on the Depreciation settings tab of the Fixed assets (FA303000) window. Financial periods can start from any date of a calendar month and last for one, two, or three months. Select one of the following options:

Fixed day
Used to set a particular date (which you specify in the Day in mid period column) as the last day of the first half of the period.
Number of days
Used when you specify the number of days (which you specify in the Day in mid period column) the system will add to the first date of the calendar month to calculate the last day of the first half of the period.
Day in mid period

The needed day to set the middle of a financial period. The option you have selected in the Day in mid period column determines how you specify the value in this column:

  • If you have selected Fixed day in the Mid period type column: Specify the particular date of a period as the last day of the first half of the period in this column. For example: If you specify 10 in this column, the 10th day of the period will be the last one in the first half of the period.
  • If you have selected Number of days in the Mid period type column: Specify the number of days the system will add to the first date of the calendar month to calculate the last day of the first half of the period. For example: If you specify 10 in this column with the Number of days option selected in the Mid period type column, for a financial period starting on the second day of a calendar month, the 12th day of the month will be the last one in the first half of the period.
First calendar year Read-only. The year that starts the book calendar.
Last calendar year The last year for generating the calendar of the book.
