# Incremental Mechanism

> Choose and verify the safest low-cost refresh mechanism for an Oracle Fusion AIDP bronze, silver, or gold node. Use when asked whether a node can be incremental, why a node re-extracts or rebuilds in incremental mode, how to reduce refresh cost, or when authoring a new node needs a refresh-strategy decision. Inspects the node grain, sources, watermark, and merge keys; live-probes whether BICC honors the source PVO lineage cursor; then recommends native BICC incremental, a verified LUD delta, a period window, or replace. Does not seed, query business payloads for analysis, or change grain/keys.
