Hi @Pierre1 ,

Actually, you don't provide this infromation in the code. You specify this information when you create dlt pipeline.

If you do not select a catalog and target schema for a pipeline, tables are not published to Unity Catalog and can only be accessed by queries in the same pipeline.

For more information take a look on below documentation entry:
