Hi @dinbaral . Assuming you download the data from schema 1 you could upload it as a dataset so you can then use in schema 2. That I think is the only way to do it.
I don’t think it is possible to link to schema 1 from schema 2 as that would necessitate it triggering and caching a generation of schema 1 in order to populate the field in schema 2. Happy to be proved wrong if someone knows better.
