The SKU of the consumable material differs from the SKU of the equipment. For Equipment, an SKU is a unique identification number of a specific material object. For example, you have a position "JBL SRX712 speaker system" in the amount of 12 pieces. So, in the Catalog GOLOVA you need to create 12 SKUs for this position. So, you will be able to track the movement and history of each individual object. 

For Consumables, this approach is excessive — you are unlikely to track the movement of each AA battery or work gloves or screws, etc. piece by piece. Therefore, you can create one SKU with a variable quantity for Consumables.

Example. 

You have two 200L barrels of glycerin in your warehouse. An SKU with a barcode is pasted on each barrel. Before the project, you pour 5L from one barrel into a canister. Here's how it will look in the Catalog. An item of the "consumable" type, which is called "Glycerin" with a unit of measurement in liters (l.). Two SKUs have been created inside this item, one for each barrel. In the card of the SKU, the quantity is set to 200. When shipping to the project, specify the number of 5. Upon completion of the project, the total number inside the SKU in the catalog will change and become 195, because it is assumed that you have used up consumables on the project.

By default, the system will create an SKU of consumables in the amount of one, in order to avoid errors and confusion. Once again: the SKU of the consumable is a common number for a group of objects. And the number of objects is set in the consumables card. 

Consumable SKU card

All tabs and fields of the Consumable Item menu are identical to the tabs and fields of the Equipment SKU card. An important difference is that in the SKU of the consumable, you can perform operations with the quantity.

Click on the "Edit" link next to the "quantity" field. In the dialog box that opens, select an action.

Buy — used to replenish balances. Here you can specify the quantity, date and cost of the purchase (this information will be saved in the history of the SKU of the consumable). After confirmation of the action, the total balance in the SKU will change.

Write off — used to reduce the total amount. Information about the decommissioned quantity will be displayed in the Decommissioned list in the top menu of the Catalog.

Move — the action is relevant when you have created several SKU of consumables. It is used to move the quantity (for example, you pour 10 liters of consumables from one barrel with SKU 001 to another barrel with SKU 002). After confirmation of the action, the quantity will change in two SKUs.

Sell — information about the sale will be displayed in the history of the SKU, as well as in the Sold list in the top menu of the Catalog.
