fmBatchUpdates - View Batch (Bridge) Data
In case you're using PHP-MySQL Bridge to work with your store DB, here you'll find the data, that hasn't been posted to your store yet. You can check logs of the changes you've made since last time you've posted changes to the live store.
At this page you can make the changes to the future data modifications. So when you post data, it will be posted with the changes you've made.
Please note, that any modifications done, using View batch (Bridge) data section won't be displayed at your current (local) DB till the time you get data from the web again.
