Hi Renee,
If you delete an account-level custom field, it will no longer be available as a column in any new or rerun reports, even when you filter those reports to last year's events. Any reports you've already exported and saved (for example, Excel files from last year) will still show the field, but future runs of those reports in Cvent won't.
Best practice if you might ever need that historical data again is to not delete the custom field. Instead, make it unusable going forward by renaming it to "ZZZ – Do Not Use – Retired 2025") so it's hidden operationally but still available for historical reporting.
Custom fields are meant to be used across multiple events, and multiple years. If you need something specifically just for one event, a Registration Question may serve you better.
