Answer 1

you can add a filter to restrict the rows being synched. Sync Framework however does not support dynamic filtering. Sync framework does synchronization based on incremental syncs of what has changed since the last sync.

for example, assuming you have a customer table and you let a user pick which customer to sync.

you will most likely store the customers that was picked for synching in another table, let's say SelectedCustomer which would store the user id. and the customer id.

when a user adds or removes a customer from his selection, you would update the SelectedCustomer. However, when you sync Customer table, you won't get anything not unless the specific customer record has been changed since the last sync. Even if a customer was added to a specific user, the actual customer record is not updated, no update, no change detected.
