What it means
SSRM tree data keeps the hierarchy on the server. The grid asks for direct children of a route instead of flattening the whole tree in the browser.
Data Models guide
SSRM Tree Data data grid documentation
Use SSRM tree data when each record already belongs to a server-owned path.
When to use it
Use it for folders, org charts, nested work breakdowns, and any data model where parent-child structure is part of the record itself. Choose tree data over row grouping when the hierarchy already exists in the source data instead of being built interactively by the user.
Implementation notes
Tree-data SSRM routes address direct children for the current path, not the whole visible tree. Keep the server response aligned to the requested route so the grid can stitch child stores into the visible outline.
