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.

Subject: Custom Session Fields - Ramifications of Deleting
Hi Cvent Community
We use custom fields for sessions and have found it very helpful. My question is if we go into the admin side of the account custom fields and delete a field that we used last year, will that field still show up on any reports we pull in the future for the events last year.
For some reason I thought if you delete the custom field, it does not ever appear on historical report again.
Thanks in advance for your time.
