How does GoZync handle deleted records?
Records deleted on the hosted side are deleted from the mobile device the next time the mobile device pulls that table or executes a round-trip sync.
Records deleted on the mobile side are not passed to the host as deletion instructions. If you want to be able to delete records on mobile and have those records deleted from the host, tag the mobile record with a "deleted" flag instead. Then include the field in your Zync layout and delete the record on the host using a server-side script.
(Having been deleted on the host / server, the record will then actually be deleted from the mobile device next time it pulls records.)
Deleting records that don't (no longer) belong to me
A record doesn't actually have to be deleted from the host / server to be deleted from the user's mobile device: the record would also be removed from the user's device if it no longer "belongs" to that user.
For example, let's say that you've scripted GoZync to only pull down your orders that are marked "Ready". And that when you push those records back to the server, you're using our Custom Field Mapping script to mark the record "Completed."
Well, next time that mobile user pulls down records, they'll also pull a list of all the orders they are supposed to have on the device: any records not on that list (because they were deleted from the host or because they are no longer "ready") will be deleted from the user's device. This makes it very easy to craft workflows where the user only has the records they need: you build a found set of records appropriate for that user, and GoZync does the rest.
Now this means that you may want to prevent users from pulling down new records if they have unzynced records on their device, but you don't have to. In the round trip syncs, for example, GoZync pushes changes before pulling them.
Here is an example of how deletes can really help with your workflow.
Turning Off Deletion
If you want to manage the deletion of mobile records yourself, you can turn off GoZync's management of it. Simply add an "Exit Script" line at the beginning of the script "Delete Records Not In This List ( $IDsToKeep )" in GoZyncMobile.
