Lineage & Impact Analysis

As of 2026-05-29

Lineage answers "where did this number come from?" (backward); impact analysis answers "what breaks if I change this?" (forward). SAP Datasphere's Impact and Lineage Analysis renders both as dependency graphs. Object-level is baseline; column-level is the standard regulators (BCBS 239) and GxP pharma need — pick granularity by compliance demand. Impact analysis is the change-safety primitive feeding change management (M084) and cutover (M075). Active metadata (derived live from model definitions) beats a stale spreadsheet diagram and is the foundation a catalog (M080) builds on. Honest limit: logic outside the platform is a lineage gap — surface it (§0i). Credibly promising "every number traces" is the senior-rate differentiator.
