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.
PPM project and work item extensible fields are powered by the generic Foundation Extensible Fields (FND EFF) system. The same four-table model used across the platform — categories, attribute definitions, assignments, and values — handles custom fields for both PPMPROJECT and PPMWORK_ITEM entity types.
