The Synchronization Server can process updates from many sources at once. To ensure updates to the same IDT record are performed in the desired order sequence numbers are used. The Synchronization Server conforms to the same format for sequence numbers as NSA transaction table. That is a 32 byte string. This means that string comparison are used for ordering purposes. If using numbers they should be right justified, zero filled. We recommend using a single pool of sequence numbers for every IDT.
