Hi! Another thing I noticed is that when the data sources are imported, the tableau hierarchies are also imported. However, it comes without the respective links.

Hi @brainy-wall-41694! I’m guessing

dm_custo_operacional

is a Data Source, and

Chave do Documneto

is a nested array within the dataset…?

Yes,

dm_custo_operacional

is a data source.

Chave Documento

is what tableau calls a hierarchy. Are database fields arranged in a specific order that facilitates drill down/drill-up.

Wonderful — thank youuuu!
