Undo and review the draft history

Use history to understand and correct a draft before releasing it. You need Model authoring. The model editor saves actions as steps; an installed release stays fixed.

  1. Expand Issues and history, or Issues, history and dry run with a workbook. Choose History. Steps appear newest first with their author, time and state: Applied, Undone or JSON edit. One step may include several related changes. A released-element change that affects stored data also shows Needs a migration, with the records, values and relationships that hold the element. A released key change needs a migration even when those counts are zero; integrations naming the key must change with it.
  2. Use Earlier steps to read older entries. No steps yet. means there is no saved step in this history. A document edit appears as JSON edit, rather than a list of visual actions.
  3. To reverse the latest step, choose Undo in the header. To reverse an older step, use its Undo action in History. Check the resulting model and Issues afterwards.
  4. If Undo the steps that depend on it too? appears, read every dependent step. Confirm only if all those reversals are wanted. Cancel keeps them. A field added later cannot stay attached to a type whose creation is being undone.
  5. Choose Redo to restore the available undone step. A new edit clears redo history. If the draft changes elsewhere, review its newer history before retrying.

Confirmation listing steps dependent on the step being undone

Undo changes the draft and takes the undone step’s part out of the proposed migration. Redo restores it; the install or Apply review reflects the steps that stand now. A migration mark records a step’s impact; activation checks the workspace’s current data again. See Migrations before installing marked steps.

Undo neither changes an installed release nor reverses published records. For concurrent edits, see Work on a draft with others.
