The SKU can be included in the "Written off" list in three ways:

– Transfer from the "Faulty" list,

– directly from the equipment SKU card in the catalog. To do this, in the SKU card, click on the "edit" link next to the "Qty" field,

– From the working area of the catalog. To do this, select the checkbox opposite the SKU and click the trash can icon above the workspace. 

The Catalog provides for mass write-off of SKU. To do this, select the checkboxes in the list of SKUs in the working area of the catalog and click the trash can icon that appears on top. If the SKUs have already been used in projects, or have been in the catalog for a long time, then a message will appear that it is impossible to delete these SKUs, and they can only be written off. In the dialog box, you will be prompted to write off these SKUs or to write off and delete them. The "Delete" action is provided for newly created SKUs (for example, by mistake). You can also delete SKUs from the "Written off" list. This action releases the SKU number, and permanently deletes the history and log of the SKU.
