When you navigate to the union schema, search for an attribute, and click on it, you can see which dataset(s) contribute that attribute to the union schema. If multiple datasets contribute to the same attribute, all of them will be displayed.

However, when multiple datasets contribute to the same attribute, determining which dataset the attribute is currently referenced in the profile store can be a bit tricky. While it’s possible to identify this manually by querying the datasets, it’s unclear if there’s a more efficient way to find this information.

Union schema shows list of schema contributing to it, but the dataset name list are misleading. I have checked it also shows those list of dataset, which doesnt even have those fields. it could be a bug in the UI ? Or may be it assumes that just if the underlying shema has the field, then dataset might also have it ?

By the way I have tried these steps in past ,

- From union schema find the list of schema contributing to that field

- From dataset, find all those schema which are linked to it. using the filter on bottom left corner. This would be one schema filter at a time.

- Then query each of the dataset to see if they have a column for that attribute. Having a column indicates that dataset contributed toward the data ingestion for that field.
