Central suspension service
The centrals suspension service handles all functionality related to suspending and recalling transactions in the POS through the Site service. All dialogs that are displayed during the suspensions and recalling are also in this service and can be customized.
If the connection to the Site service is interrupted or is down, the POS saves the information to a local database. The information can then be sent to the central location at a later time when the connection has been re-established. Information about how many sales have been suspended at the terminal can be viewed in the status bar of the POS.
The suspended transactions from all POS can be viewed centrally in the Site Manager but that functionality is handled by the Central suspension plugin in the Site Manager not this service.
Note!!! Some of the dialogs in this service use Dev express components and they cannot be opened in designer view in Visual Studio unless Dev express components v 15 has been installed.
Configurations
Some configurations are needed in the Site service profile. At least one suspension type has to also be created.
If the suspended transaction should be printed on a station printer using the hospitality functionality some additional configurations are needed in the hospitality part of LS One
