Those that are used to using conditional formatting in excel will find that an Alerter is the Business Objects equivalent. Conditional formatting allows the user to alter the display of a cell based on its value.
for example:
If cell value = Yes then colour text green
Alerters are a good way of drawing the attention to the consumer to a particular element or value – for example : overdue payment dates may be coloured RED
Alerters are also a great way of adding context or focus to a set of information – for example : a simple traffic light system so that the a state of an indicator can easily be identified.
if Value LESS THAN 0 then RED
if Value EQUAL TO 0 then AMBER
if Value GREATER THAN 0 then GREEN
