# Table Selection

> Use all scanned tables or pick specific ones — for loading and for modeling.

Every source carries a table selection, chosen from what its schema scan discovered.

## Selection modes

* **Use all scanned tables** (the checkbox on the source's Config tab): Platinur loads every
  table the scan found.
* **Selected tables**: uncheck *Use all scanned tables* and pick. Unchecking starts from
  **nothing selected** — you choose exactly the tables you want, from zero.

The table list always shows **all** discovered tables; unselected ones are merely unchecked,
never hidden — so you can always see what you chose to leave out.

## Where selection matters

* **Integrations**: controls which tables are loaded from a configured source, and which
  tables carry per-table cursors and primary keys for
  [Append and Merge refreshes](/sources/load-modes).
* **Models → Build**: controls which source schemas and tables are modeled into dbt.
* **Assistant context**: keeps generated changes focused on approved source tables.

## Recommended practice

Start with selected tables. It keeps the first build smaller, improves review quality, and
avoids modeling unrelated operational tables. Adding tables later is an additive model
update, not a rebuild.
