Freeze and unfreeze data
As a data manager or CRA, you can prevent site users from editing case form data, to use it in data extracts and analysis. You can freeze data at a visit, form, and question level. Site users can only update a question after you unfreeze it.
You can freeze data for both complete and incomplete visits. All question types can be frozen, including instances of a repeating form, coding questions, and individual questions in question groups.
When it comes to repeating forms, you can only freeze data in a repeating form instance when that form instance is completed.
If you or another user at a sponsor organization raises a query against a frozen question, that question remains frozen and the query can be answered by a site user. You can only unfreeze data at a question level, one by one.
