Batch number

Last updated: July 20, 2023

An identifier, which, together with an item prime identifier (part/item number), identifies a quantity of the same item that has been processed as one group i.e. fabricated).

Batch quantities are always associated with batch numbers, which are allocated to maintain records against the item number/batch combination. This can include:

Object baseline,
Build history, and
Waivers, deviations and modifications.

Items identified in batches are managed in the same way as serialized items. A batch number is typically allocated to a quantity of the same item for which:

There is no need to maintain records per individual item,
It is impractical to maintain records per individual item, or
When the item cannot be distinguished as a set of individuals (e.g. a volume of a liquid chemical).
