QMS uses a Stock code library to define a catalogue of stock codes for use on a project. This library is used throughout QMS for validating stock code data entry in the various QMS elements, and for the allocation of stock code descriptions.

Use of a stock code library minimizes one of the main sources of errors in the materials control process, the mistyping of stock codes and their descriptions.

The Stock code library can be created manually, sourced from another project, or imported electronically from an external application.
