You can now trace where each value in a Dimension came from, directly on the dimension page.

A new Dataset sources column shows, for every value, which dataset (or datasets) introduced it. Before you clean up or debug a Dimension, you can always tell where a value originated.

• When a value is fed by more than one dataset, all of them appear on the same row.
• If an unexpected or unassigned value shows up, you can see at a glance which dataset brought it in.
• Filter the Dataset sources column by one or more datasets to focus on a single source, or select Other sources to surface values that weren't introduced by any dataset.
