Make DEAR POS Receipt Number unique even when offline

started a topic 6 months ago

DEAR POS takes the next receipt number from the server, but if POS is offline it uses/repeats the last number until it goes online again.  This is not very 'unique'. It diminishes the value of the of the reference number and risks the wrong order being accessed.

We have a travelling salesperson who regularly visits remote areas where there is no network coverage so this duplicated reference issue occurs often.
