The data lineage function enabled by Data Services is directly integrated into the
BI workspace of the BI end-user. By right-clicking on a number, users can choose
to trace the origin of that figure back to where it comes from, how it was
computed, combined, enriched etc. This level of transparency boost trust in your
BI initiative and helps users make confident decisions since they have full
certainty of why a given figure is correct and what it really implies. There is also
Information steward that manages all your metadata and data governance.
