Snapshots
Overview
Snapshots is the searchable list page for named snapshot definitions. Use it to find a snapshot by name, update SQL, or description, review the available entries, open an existing snapshot for editing, create a new snapshot, or delete one that is no longer needed.
Function
The page combines a search filter with a read-only result grid. The search field narrows the list by snapshot name, update SQL, or description, and the clear-filter button reloads the full list.
Double-click a row to open the Snapshot page, where the snapshot name, description, and SQL expression can be maintained. Use New to start a new snapshot from the list, or Delete to remove the selected snapshot after confirmation.
Access
Open the list from the Snapshots node in the navigation tree or from the Snapshots command in the DWH toolbar. The navigation tree also provides Add snapshot, and each existing snapshot provides Edit snapshot.
