For internal purposes, the application offers the option of sending messages (notifiers) to system users. These can be managed indirectly as a result of events arising when processing transactions as well as actively by starting the “Send Messages”.
If these notifiers are automatically managed by the system, normally pre-defined users (users of the transaction, for example) are given a display of problems that have arisen with respect to single transactions. Notifiers are displayed in a popup window.
