Costing and mass
Cost and mass fields help planning review, but they stay bounded by the current workspace’s pricing access and configuration.
Costing source
Workspace costing uses the current costing profile and server-backed permissions where required. The interface should never invent supplier prices or mass values when those fields are unavailable or outside the approved scope.
Visibility and scope
If costing or mass are hidden, treat that as a policy or data-availability boundary rather than a rendering failure. The rest of the planning workflow can still remain usable without exposing protected commercial fields.
