Introduction

This Data Exchange Set (DEX) 1 - Product Breakdown for Support - utilizes ISO/DIS 10303-239:2004 Product data representation and exchange: Application protocol: Product life cycle support (hearafter referred to as PLCS or AP239).

This supports the initiation and progressive development of the Product Breakdown for Support for a particular product, whose design (product structure) is evolving over the product's life cycle.

The viewpoint of the product structure, and hence the Product Breakdown for Support, could be at any point in the product's life cycle. This may be from the design baseline (as-designed view) through to a product baseline (as-designed / as-built / as-maintained view).

The DEX allows you to update the product structure using new versions of exchange data. The DEX also provides the capability to create and populate 'placeholders' within a structure to hold or point to reference data.
