# Is it possible to reverse or undo the update?

Yes, it is possible but limited to stock and price. This can be achieved by [downloading the change logs](https://help.stock-sync.com/en/article/how-to-check-stock-sync-change-log-not-in-feed-and-not-in-store-jts3sc/?bust=1735792213836) and setting up another update feed to refresh the "Before Qty" column. Only the quantity and price can be updated before changes, other fields cannot be modified.


1. Download the latest change log from the feed detail page.
