Disable a data item from syncing
When you are adding a data item to Sync, the Enabled option is selected by default. As the name suggests, this option enables the item to be synced.
You might prefer to disable an item, so Sync temporarily removes it from the sync process. If this is the case, clear (uncheck) the Enabled checkbox, either when adding or editing the item, or on the Data Items tab.
Disabling an item doesn't delete the item; it just means that no new data for that item will be synced as long as it remains disabled. The Last Successful Sync date will not change.
To re-include that data item in the sync process, select the Enabled box.
