## Fields

**`name`**: `String!`

**`isCommentRequired`**: `Boolean!`

Whether a comment has to be given when a document is cancelled with this reason.

---

**`isSystem`**: `Boolean!`

Whether Wawi created the reason itself during setup. System reasons cannot be changed or deleted, because Wawi relies on them, for example as the fallback when a cancellation comes in without a reason.
