# Depreciation by CMDB Item Type

For example, you might create a depreciation schedule called **IT hardware write-downs**. You can link this to the desktop, server and laptop CMDB item types. However, you would apply a different depreciation method to servers than you would to desktops and laptops, because they depreciate in a different way. When the **IT hardware write-downs** schedule is run, ASM Core applies the chosen methods to each separate CMDB item type.

You can create as many depreciation schedules as you wish and can link any of these to any CMDB item types. They can be linked in a many-to-many structure, so that one CMDB item type can be linked to several depreciation schedules and one schedule can be linked to multiple CMDB item types. When you link schedules to CMDB item types, you can also specify which depreciation methods to use from the Depreciation Method screen for each CMDB item type.

#### To configure depreciation, you will need to carry out the following:

1. **Define your CMDB Items.**
2. Create one or more depreciation schedules.
3. Define the parameters for one or more methods of depreciation.
4. Link the schedules and methods to CMDB Item Types.
5. Create and define your batch run parameters for each depreciation schedule. This executes the depreciation calculation against the CMDB Items.
6. View a log of all the batch runs.
