Every project has metadata that doesn't fit into predefined fields. Cost centres, risk ratings, compliance classifications, custom priority schemes — these vary by organisation and even by project. Raytio PPM handles this through categories and custom attributes, a structured extension mechanism that lets you add typed fields to work items without changing the schema.
The extensible fields system lets you attach typed custom attributes to any platform entity — without writing code or changing the schema. Tenant administrators define the fields they need, assign them to specific entity types, and start recording values immediately.
This guide walks through creating categories, defining attributes, assigning them to entity types, recording values, and querying extensible field data. It uses a DCM (Device Control Management) vending machine as the example entity.
