I am using QB sync with a csv table stored in Dropbox. I am using the option to keep all records and add new, so that all records are preserved. However I would like to identify all records that have been deleted from the source csv table and mark them as inactive in QB. Newly added records and modified records can be identified based on the Date Modified and Date Created fields. However I have not found a way to identify records that were deleted from the source table versus records that are still in the source table but just not updated.
