Retraining a Field or Table ID model is not necessary if one, or some combination, of the following properties were changed in an existing field’s settings:
Field name
Output name
Supervision

Identification Supervision
Field ID models
Field ID models do not need to be retrained if any of the following layout changes are made:
Removing fields
Changing data types
Adding new fields or toggling existing fields’ Multiline setting
If you use existing training data to retrain a model with new fields or fields whose Multiline setting is updated, those fields are not included in the training. Those fields are unsupported until you retrain the model with enough documents that include annotations of the new or updated fields.
Table ID models
Table ID models do not need to be retrained if any of the following layout changes are made:
Removing fields
Changing data types
On the other hand, Table ID models will need to be retrained after the following layout changes:
Adding new fields
Toggling the Multiline setting
