Auf dieser Seite

Overview of the order in which the API rules assigned to a BO run, depending on the action.

Create

  1. StateChangeRule to the initial status (only with a status model)
  2. InsertRule (parent BO) → mandatory-field check
  3. InsertRule of subform BOs (only with own status model) → mandatory-field check
  4. StateChangeFinalRule (initial status)
  5. InsertFinalRule of subform BOs, then of the parent BO

Edit

UpdateRule (main BO) → mandatory checks main/subform → UpdateFinalRule (main BO).

Delete

Subform records are deleted along with the parent (from Nuclos 4.38 only with delete cascade on the reference attribute); DeleteRules run for subform BOs only with their own status model.
