When you press the Suspend button on the POS, the POS transactions and related lines are sent to the specified remote database.
Retrieve
When the cashier requests a list of suspended transactions from the remote database, only the headers are sent back to the local database.
After selecting a specific POS transaction from the list, the whole transaction is requested from the server. If successful, the transaction is deleted from the remote database. The transaction is now only available on the POS and can be finalized, suspended again, and so on.
Error Handling
If it is not possible to suspend the transaction to a remote database, the POS will suspend it locally.
If it is not possible to retrieve the transaction from the remote database, the POS displays an error. There can be two reasons for this:
The suspended transaction is stored in the remote database and cannot be retrieved. In this case the customer has no other option than to rescan the items.
The POS that suspended the transaction was unable to store it in the remote database. In this case the customer must return to the POS terminal where the transaction was last suspended to retrieve it.
