Consumables life cycle Consumables are assets that are not tracked individually, but as a group of the same model. The group of consumables has one or more of the following traits. Same location Same state Consumed by the same asset, typically as accessories or parts Some common consumable assets include computer mice, computer keyboards, and pencils. The base ServiceNow system includes the Consumable model category. The first step in working with models is to create a model within the model category for an individual consumable asset. Items such as keyboards and computer mice are often tracked as consumables. Consumables cannot be pre-allocated. Consumable assets are stored in the Consumable [alm_consumable] table. Consumables follow a slightly different life cycle from other assets. Stages of consumables The consumable life cycle stages are as follows.

The Consumables list contains two records for the consumable in the specific stockroom: one with a state and substate of In Stock and Available (if you did not consume the entire quantity), and one with a state of Consumed. If a consumable is not in the process of being transferred to a different stockroom and information in the data record is the same, similar records are merged automatically. After a consumable is consumed, the record remains in the system for reporting purposes.
